The Nakamichi
RX-202, Auto-Reverse (the best way)
Stereo Cassette Tape Deck. Great deck for doing your tape
transfers if your tapes were recorded with no NR or with
Dolby B or C.
It's also quite 'fun' to operate. While I sold these when new as a
Nakamichi dealer back in the mid-late 1980's, I had forgotten how well
they function. The transport commands are VERY precise and quick. You
might think that if the tape has to come all the way out, flip a 180,
then re-load and go back into play mode might take a few seconds. You
might. However, in reality, I think it's less than and certainly seems
like no more than about 1 second! It's quite the 'head turner' when it
functions.
Nakamichi RX-202 Features include:
- 4 Motors (Capstan, Reel, 'Cam' {head control} and
UDAR chassis)
- 3-Mode, "UDAR" (Unidirectional Auto Reverse) for related 'cool
factor', check next feature
- Music-Sensing Circuit monitors playback and fast-forwards through
blank 'tail' of tape to provide less interrupted playback when
auto-reverse is engaged.
- Special, PR-2D R/P head separates the head into 2 parts so there's a
head for playback and separate Record head instead of having them
combined as they are in most "2 head" decks.
- Super-hard, Record / Playback heads - Super Hard,
High-Performance,
Laminated Sendust, semi-discrete,' R/P head w/ EXTREMELY
NARROW gap, allowing for 20-20,000Hz
performance - IC Logic / Touch tape transport with
motor driven 'cam control mechanism'
(From the original Nakamichi RX-202 brochure; "Microprocessor-controlled
silent tape transport ensures smooth operation and minimum flutter") - Selector for Normal (EX / I) &
CrO2 (SX / II) & ZX (IV Metal) Tape Types - Tape Type EQ selector for 120 or 70
μsec
tape
- Auto-Record Standby automatically rewinds the
tape, skips over the leader, records a 6-second bland header and
activates the "Record Standby Mode". Pressing twice during recording,
Auto Rec Standby instantly advances the tape to the end, switches to
Side-B, skips the leader, records a blank header and enters "Record
Standby". Pretty cool if you do a lot of recording. This is especially
handy if you start recording, the realize you screwed something up and
need to start again. WAY less buttons to push.
- Electronic "Master Fader" for professional, 2 or
4-Second (selectable) Fade-In and Fade-Out when recording -
LED "VU" signal level meters w/
37dB of range - 4 Digit,
digital tape counter - MPX filter (for filtering the 19kHz pilot tone out of FM
transmissions) - Dolby B & C NR
-
Variable
Output Level (one of our favorite features on a tape deck)
- 1/4" Headphone jack (follows Output level control so you can control
the volume without blasting your ears off) - Record level control with L & R balance - Memory Stop /
Play for counter -
Standard RCA
I/O's on rear panel
- Timer Play
/ Record (has the option to immediately engage "Play" or "Record" modes
when power is sent to deck either via the 'Power' button or the AC Power
cord via a switched outlet if the 'Power' button is already engaged)
- "WORLD AC POWER"™
allows unit to be operated on 50 or 60 Hz AC
and 100-240V. Currently set up for US / North
American AC power.

Did you know? 3-Heads vs 2-Heads;
'Normal / 2-head' decks have an erase head and a
'combination' playback / record head that serves
'double duty' depending on whether it was being sent a 'record signal' or
receiving a 'playback signal', thus the "2-heads". Most 'higher end' cassette
tape decks / recorders offered '3-Heads' for superior 'recording' performance.
The 'Third-head' was a separate playback head, positioned immediately after the
record head to allow 'almost instantaneous' (about a third second behind, as a
cassette shell only has 'so many openings') monitoring of the actual recorded
signal on the tape, as opposed to simply monitoring the 'input' signal to the
deck. However, the '3rd-head' 'generally' does nothing for playback of already
recorded tapes. There's some credence to the argument that playback heads can
have a closer 'gap' designed into them than record heads, so if you get a
'3-head' deck that has a playback head with a closer gap, then it would (could)
offer better playback performance. Possibly, if you check the specs (if
available) and find that is the case, the heads aren't worn and the balance of
the deck is of substantial quality. Many better 2-head decks offered playback
heads in the 18-20kHz. I get a lot of folks that are shopping for cassette
decks, with only the purpose of 'playing back' their old tapes, but thinking
they want a 'Three-Head Cassette Tape Deck' because they've
been 'told' that it would be better quality. Since the third head does
'little to potentially nothing' for playback (except it does
make doing final audio adjustments / fine biasing adjustments when servicing
MUCH easier), there's minimal reason to hold out
for that feature, nor to pay extra for it…unless you just want it,
or you ARE going to be 'recording' or it's coming along on a deck
that has other features you wish. Now if you are going to be
'recording' then I 'HIGHLY' recommend a deck with 'Tape Monitoring' via
the third head, thus "3-Heads"!

front panel (probably from a CD player or EQ sitting on top
at some point) that's only seen when viewed from above (See
photos above.) Great for transferring your no NR or Dolby NR encoded tape
collection to CD, Hard-drive or MP3. Built very well! Looks like
new, works and sounds great. Comes with an 'e-copy' / pdf of the
Nakamichi 481 owners manual and original Nakamichi 481 Brochure.

dbx NR
#...C082
Circa early 1984-86
Made in Japan

AC POWER"
™ for
sale
Initial 'pre-test' conditions; Fast Wind
typically sluggish / intermittent (almost
always due to idler tire issues). Play and Record actually
seem to have basic function and perform decently, but did exhibit some
flutter. Crack in Level meter plexi window (we sat on this deck for
about 6 years, before starting on it, waiting to come across another to
pull the window from and it never happened. I sold model deck when new,
and due to it's relatively higher price, not many were sold, so not many
are out there on the secondary market for parts. Thus finally, we
decided to go ahead and restore it with the window crack as it's such an
amazing deck both considering features and performance.
Addendum; following initial restoration, we found that when monitoring
playback for hours, that occasionally the speed would slow down for a
few moments randomly throughout the day. We had a Technics RS-68R that
had just come in that had head issues, so we pulled the transports and
swapped them, and discovered that the issue followed the transport (yes,
we checked the power supply, monitoring it when the motor slowed, but
observed no variation in the power supply Voltage or current). We then
pulled the motor and determined that it had too much drag at certain
points through it's rotation. We swapped the motor and that finally solved the
speed issue.
ü
Our technician has completely and EXTENSIVELY gone through and
'Certified' this unit which involves complete disassembly of
the transport (not an easy task on this table), cleaning inside
and out, DISASSEMBLING, cleaning and re-lubricating all internal
mechanisms and the balance of efforts listed below.

Both capstan flywheels removed.

Capstan's cleaned, burnished and re-lubed prior to re-install
(also had their belt surfaces cleaned and burnished as mentioned further
on. Both
rubber pinch rollers removed from arms and have been
resurfaced on drill press and chemically reconditioned.

During that process, we discovered that both pinch
roller arms had cracks in their axle mounts.

While those may have been
fine left alone, we went a head and changed them out from the other
transport which had 'crack free' arms.
Heads have been cleaned and de-magnetized as well as the entire
transport. Power supply tested for correct Voltage
and current to the motor. While the motor
issues likely caused some of the flutter issue, we also found a random
build-up of rubber debris on the drive pulley and the capstan flywheels,
that would contribute to that as well.

Main
capstan / flywheel belt replaced with modified
#FR10.0. New counter belt installed.
Following initial rerfurb, Main / Cap motor replaced
with another original / OEM motor due to faulty bearings in one
originally installed. All internal pots, switches and controls cleaned and tested for
noise-free function. Floor noise tested to -74dB. All fluorescent displays and LED's
working fine. Both spindles in perfect alignment. FF, REW, & Play
transport functions all test perfectly and controls positively
responsive. Eject door mechanism operates smoothly. Heads in good shape
as well, with many years of performance left in them.
ü
Speed adjusted to
99.70% accuracy with 1kHz factory calibration
tape (meaning 1kHz calibration tape plays back at 1003Hz +/-
1Hz {the service manual spec states +/- 15Hz
is acceptible BTW})
ü
Head alignment and azimuth at 125Hz, 1kHz and
factory 10kHz, Sony alignment tape and O-scope for peak performance
(this adjustment alone gained ~6-9dB output amplitude!)
for BOTH directions for 'peak performance' with
Oscilloscope
also w/ STL and TEAC
MTT-257H calibration / alignment tapes. Both channels now even output.
ü
Both Internal playback amplifier channels adjusted with Volt meter,
O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both
channels now even output.

ü
Meters adjusted to even zero with symmetric input with Volt meter,
O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both
channels now even output.
ü
Both Internal Record amplifier channels adjusted with Volt meter,
O-Scope and sine-wave generators and 'pink / white noise sources'. Both
channels now even output.
Azimuth verified for BOTH directions and remained consistent.
Playback meters zero with factory test
tone tape.
ü
Plays perfectly and after adjustment,
records AMAZINGLY well with 1kHz @
0 dB = 0dB! on High bias type
tapes. (Following the extensive restoration, we did
'test recordings' of a 'ddd' CD on Maxell 'XL-II' High Bias
with the following results;
w/ no NR; 1kHz @ 0dB; L=0dB & R=0dB
w/ Dolby B; 1kHz @ 0dB; L=0dB & R=0dB
w/ Dolby C; 1kHz @ 0dB; L=0dB & R=0dB
w/ dbx; 1kHz @ 0dB; L=+2dB & R=0dB
DDD Pre-Recorded CD material sounded fabulous on Maxell UDXL-II
and dbx engaged.
(we really put them through the paces, testing both with
well mixed, recently recorded CD material and CD recorded / factory test
tones looking for correct head Azimuth and speed accuracy).
Following all of the above, deck now performs VERY
WELL!
____________________________
The Technics RS-B78R with
Auto-Reverse, Dolby B / C & dbx
NR. Great deck for "all around use" home
or project studio. And since it utilizes DBX NR, it can squeeze up to
110 dB of dynamic range onto a cassette tape (normally the best
recorders might do up to 72 dB with Dolby engaged. Another great feature
of this model is that the fast wind mechanism is completely gear
driven and does not us a rubber tire. Deteriorated / glazed rubber fast
wind idler tires are THE COMMON issue with decks not fast forwarding,
rewinding and / or eating tapes. That will never be an issue on this
particular model and many Technics decks w/ 'gear driven' reel spindles.

especially since it has dbx NR. Great for simply 'listening' as it has
'auto-reverse'. Also great for transferring your tape collection to CD,
Hard-drive or MP3. Obviously it's main 'black-eye' is
the crack in the meter window (again, we searched for probably 6 years
for a replacement that was economically practical to no avail). Works and sounds great!
Performs probably better than when new

- NOTES ON PURCHASING A VINTAGE
CASSETTE DECK -
I own and have owned
‘hundreds’ of cassette decks. I started selling them ‘new’ in
the early 1980’s.
Very few of the decks that we have on our ‘incoming’ shelves
will function to any degree of ‘practical usability’, if at all,
in their ‘as found’ condition. So it amazes me at all the
articles out there on “How to Buy a Used / Vintage Cassette
Deck”, and no one seems to mention how the ‘clock needs to be
rolled back’ 30-40 years on one to get to a level of ‘practical
usefulness’. They all want to mention
to make sure it’s got the right ‘features’ for what you need,
that it’s in “good condition” (typically referring
to its often purported, “minty” looks), that
the shipping is “reasonable”, the
methods of payment work for you, and
that the ‘sellers feedback rating’ is adequate….
WHAT ABOUT IT’S INTERNAL CONDITION????? IT’S GOT
20-40 YEARS UNDER THE HOOD!!!
There’s
lots of ‘rubber’ and ‘lubricated parts’ inside a cassette deck.
‘Time’ is NOT a friend to either. Rubber can do a few things. It
can crack, stretch, break, glaze over (think about how a ‘pencil
eraser’ gets after about a year in a drawer), or turn back to
its original form, which is a ‘gooey / tar’ substance. Oil and
grease ‘gel up’ and stop being lubes, and start becoming ‘glues’
(think the grease caked under an old / vintage car / tractor. It
has to be ‘chipped’ away with a putty knife). Both of those
aspects and others affect a tape deck’s (or turntable, or VCR or
camcorder, or CD / DVD player, or film projector, or just about
anything that is powered by electricity and has moving parts
(AND THERE’S A LOT OF MOVING PARTS IN A CASSETTE DECK)
performance. Most folks assume that if you
simply 'change the belt(s), then the deck is 'good to go'. "Not
even close". Most cassette decks also utilize an 'idler tire' to
drive the tape reels, not only for 'Fast Wind' functions, but
also for 'Take-up' reel function. This tire becomes 'glazed',
cracked, deformed and / or disintegrated, and a deck WILL NOT
function correctly with 'tire' issues. The 'kicker' is that the
'idler tire' is almost always 'buried' deep within the transport
mechanism which typically requires a near complete disassembly
of the entire tape transport to even asses if a replacement tire
can be found, an available one modified, or if one can be
fabricated.
Thus following is a list of questions to ask about
any tape deck…
How is
its overall ‘Speed’? Inaccurate speed is one of the first
‘tell-tale’ sign of a decks overall heath. You won’t likely be
able to tell without an accurate ‘speed / test tone /
calibration’ tape and a frequency counter. If you’re
not a musician, not ‘musically inclined’, or are ‘tone deaf’
maybe you won’t notice, but most folks will notice ‘something is
not quite right’ when listening to a slow (or occasionally fast)
running tape. Just throwing on a new belt, doesn’t address speed
accuracy. Most mechanisms will need to be disassembled, cleaned
and re-lubed before any speed adjustments can be attempted.
How ‘Steady’ is the speed? This refers to ‘WOW &
Flutter’. This generally won’t be noticed until you put on a
tape with a ‘steady tone’ or a musical piece with sustained
piano notes. Then ‘Flutter’ issues will
drive you nuts. Also can be noticed with sustained string
instruments. Just wait till there’s violin with vibrato, then
added on top is ‘out of time’ vibrato caused from excessive
‘Flutter’ of the tape transport. If someone
just throws any selection of music in, or a 'spoken word' tape,
they'll likely not notice the 'Flutter' issue. ‘WOW’
is less of an issue in cassette decks, but can occasionally be
caused by ill-fitting / wrong belts being installed.
Does the
deck ‘fast wind’ at ANY AND ALL positions on the tape, and will fast wind,
BOTH WAYS
throughout an entire tape,...repeatedly...Every
time? While playing does the ‘take up’ pulley / reel run
correctly, or is it ‘jerky’. Is ‘fast wind’ (in either or both
directions) smooth, or jerky. It will typically be jerky and
intermittent if it functions at all. If it
doesn't turn correctly / sufficiently in 'Playback' mode, that
will cause the deck to 'eat tapes'!
This is caused by a
‘glazed’ / cracked ‘idler tire’, and about 99.999999% of decks
are going to have a glazed or cracked or otherwise deteriorated
idler tire’. It's 'decades' old rubber. It
almost HAS to be compromised. You usually can't 'dodge physics'.
AND those things are not easy to address. The idler tire will
almost always be ‘buried’ a few layer inside the transport. Then
once you get there you go on the hunt for a replacement, only to
find that there were dozens or hundreds of rubber, idler tires
made, only a few of which are still available, and none of which
will fit correctly. So now you have to make the choice (at least
of you want to move forward with a decks restoration) as to
whether you substitute an ‘O-ring’ (often works as a sub) or you
take a tire that is close to fitting, and modify it to function
correctly.
How is the condition
of the heads, regarding 'head wear'? It takes and 'experienced
eye' to 'visually' estimate the condition of tape heads.
Excessively worn heads, will never sound the way they should,
with any amount of adjustment, and you can't just go into your
local 7-11 and pick up a new set. Replacement heads for a
specific deck, will likely need to come from another of the same
(or darn close) specific deck. Having the heads 'lapped' was
once a sometimes viable possibility, but that is, for the most
part, a 'long, lost art'. Even if you manage to acquire
replacement heads, they have to be installed correctly. That
will require alignment tapes and test gear (O-scope and / or
milli-Volt meters) and a lot of patience.
If the deck is ‘auto-reverse’, how’s the condition of the
gear in the mechanism that ‘spins the head’? They are commonly,
slightly ‘cracked’. There is note a practical fix for that. The
head will go part way and ‘lock up’. If you can get it to go
‘back’ to its original position, just leave it, and accept that
the deck is not ‘auto-reverse’.
When the tape gets to the end of it's
travel in play and fast wind modes, does the decks 'auto-stop'
mechanism work? Every time?
Does the tape counter work, and
spin smoothly throughout the entire length of the tape? Every
time?
How’s the
‘azimuth’. Yes, I know it’s not a word that you use every day,
but it’s vitally important on a tape deck. When the azimuth is
out of alignment, a tape will sound ‘muffled’ (loss of treble)
and / or ‘out of phase’ (not much bass). While you can use a
‘pre-recorded’ tape and get it close, it’s really only adjusted
correctly and COMPLETELY by utilizing a ‘calibrated alignment’
tape and an O’Scope or at least a ‘milli-Volt’ meter.
How many
‘dB’ down does the deck playback from its recording level? If
you record a signal at “0dB”, how far does playback deviate from
that? You should usually expect 3-6dB if the deck is in
‘reasonable’ condition. If it’s down 10 or 12dB (or more) you’re
not likely going to be very happy with its recording quality.
Unless it’s simply due to dirty heads, addressing this is fairly
complicated for all but the technically qualified.
Is
playback even out of both channels and via both meters? You
can’t just put on your favorite tape of ‘Death-Polka Favorites’
(or some other 'recorded program material'
and listen to it to make an accurate determination. You would
need a calibrated test tape (with 'constant'
test tones), and an O’scope, or at least a
millivolt meter to first make sure the playback head is in
alignment, then the internal playback amplifiers are producing
an ‘even amplitude’ and then that the meters are both
‘mechanically’ adjusted correctly and that their ‘voltage feed’
is evenly adjusted. Don’t know what any of that means? Then I
wouldn’t be ‘messing with it’.
Do you hear any 'crinkling / scrunching'
noises with your ear right up next to the transport, and / or
when you pull out a tape that has been played on it, is there
evidence of 'crinkling / wrinkles / creasing' on the tape
section that just went past the pinch roller?
Is there
a loud, obnoxious ‘motor boating’ sound that and or your meter(s)
are cyclically ‘pegging’? No. How about after the third time of
putting the deck into record mode? Or the 6th time or
the 20th time? Then the there’s a problem with the
internal record switch (or it needs to be flooded / cleaned).
(this issue is usually only a potential problem on a deck with a
‘mechanical internal record switch’, and not more ‘modern decks’
that use ‘electronics’ to switch the deck in and out of record)
Does the deck make any extraneous noises when in play /
record, such as squeaks, growls, scrapes, grinds etc? if not
immediately, how about after 15 minutes, a half hour, an hour or
a day? In all modes?
Are the ‘Recording Level’ control pots ‘quiet’ or do they
need to be cleaned?
Do the “Source / Monitor” or “Tape EQ” switches quiet or do
they make noise and need to be cleaned?
If the deck has ‘Auto-Tape-Type’ sensing, is it triggering
correctly? If not, that could mean an issue with the mechanism
trigger tab, or a dirty / compromised micro switch.
If the deck is equipped with any type of noise reduction ie;
Dolby B, C, dbx etc, is if functioning properly? We don’t see
issues with that often, but it does happen.
Is the deck
quiet when playing back a ‘blank tape’ or better yet, a cassette
‘shell’ with no tape in it? (some decks will not allow this test
easily, as it’s ‘auto-stop’ mechanism is triggered by the tape
counter, which is typically tied to the ‘supply’ reel and if
that reel is not moving then the deck will go into ‘auto-stop’
mode.) This is ‘floor noise’ and is not to be confused simply
with ‘tape hiss’, which is why we want to hear the transport
moving without tape passing the playback head.
How is the 'quality'
of the recording and playback? Bad, distorted recordings can
also be due to Bias issues (besides the above mentioned "worn
heads", azimuth alignment errors and dirty controls and
switches.
Are all of the indicators and lights working? These aren’t
typically ‘functional deal breakers’, but can definitely
increase or decrease ‘curb appeal’.
If 'analog', do the meters settle at their
left most index line? Do they both respond quickly? Do they
'stick' at any point in their travel? If 'really pegged' do the
get stuck at the top?
Does the ‘well door’ close and latch, EVERY
TIME and correctly, REPEATEDLY?
Those would be most of
the ‘high points’ regarding the functionality of a tape deck.
Once you, or someone
technically qualified has addressed AT LEAST ALL of the above,
then we can talk about how ‘minty-fresh’ it’s cosmetics are.
I get the question
of, “what’s the best brand / model” of tape deck out there.
Well, 25-50 years ago, when you could go to a few ‘real audio
shops’ and take your pick of a dozen or two NEW tape decks, that
question held much validity. Now my opinion of the
"which is the
best deck", is the “one that has been properly refurbished /
restored / fully service to a level of ‘proper utility’,
recently, by someone qualified to do so”.
A QUESTION:
Most folks know the difference,
without too much thought, between a Chevrolet ‘Corvette’ and a
Chevrolet ‘Chevette’. If I ask "which is a better car,
a ‘Corvette’ or a ‘Chevette’", most folks will answer
"the
Corvette” (barring all the arguments based on other personal
opinions)…Now, I’ll give you the rest of the story. The
Corvette has been sitting in a barn for the past 25 years, and
hasn’t been started since it was parked there
originally. Or it was in a flood. Or it’s had a dog
living it, or a rat has built a home in the dashboard, or the
engine was blown by the 'now deceased
owner’s son', or, or, or…
Now the Chevette has just been thru a
qualified auto repair shop, and had the engine
compression checked (and was within spec), new plugs / wires /
dist cap, timing adjusted, new starter, alternator checked for
charging, new battery, the coolant flushed, the clutch replaced,
the brake system flushed, new calipers, drums and shoes, new
belts, carb rebuilt and properly jetted,
vacuum lines checked for leaks and replaced, air
conditioner serviced, new seat covers, new tires, new wiper
blades, windshield cleaner system replaced, cracked windshield
replaced, all lights tested / replaced, horn
checked, wiper motor / mechanism checked / lubed, and
thoroughly test driven around town, starting and stopping, on
the highway at all speeds. It was started in the cold weather,
and once warm, started again. Repeatedly.
It is pretty much doing what it did when new. And you need to
take a trip across the country tomorrow. Now
I ask again, "which is the better
car?"

ü
Our technician has completely and EXTENSIVELY gone through and
'Certified' this unit which involves total disassembly of
the transport, cleaning inside and out, COMPLETELY
DISASSEMBLING, cleaning and re-lubricating all internal
mechanisms and the balance of efforts listed below
(incredibly difficult on this deck!!!).

ü
Heads inspected for excessive wear (obviously we do this 'early
on' as 'excessive' wear will usually negate any further
restoration work).
ü
Main Capstan / Flywheel belts
replaced w/ #42-450 & #42-980.
ü
Counter belts
replaced w/ #42-260 & #42-1060.
ü
Rubber pinch roller mechanism bushings & axles cleaned of old
lube, reconditioned and re-lubed.
ü
Capstans motor had
it's bronze bushings lubed w/ 30wt
ü
Capstans cleaned /
burnished
ü
All internal trim pots, switches and controls cleaned and tested for
noise-free function.
ü
All meter lamps and LED indicators working fine.
ü
Both hub spindles in perfect alignment.
ü
"FF, REW, & Play transport functions all test and
controls tested for 'positive / accurate' responsive"
is what we normally like to say, but due to the internal design of this
one, we were not able to get it to perform 100%, EVERY time.
Occasionally the 'STOP' button will have to be pressed a time or two, or
another button will need to be pressed to then be able to engage 'STOP'.
Other buttons sometimes 'hang up' temporarily, but usually selecting
another transport function will 're-set' them as they're 'self
cancelling / mechanical' with an internal mechanism that was unusually
difficult to service and get to the current 'usable' state.
ü
Heads in great shape as well, with many years of performance
left in them
ü
Heads have been cleaned and de-magnetized as well as the entire
transport.
ü
Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for
BOTH directions for 'peak performance' with O-Scope and w/ STL
and TEAC MTT-257H calibration / alignment tapes. Both channels
now even output for PLAYBACK..
ü
Both Internal playback amplifier channels adjusted with Volt
meter, O-Scope and w/ STL and TEAC MTT-257H calibration /
alignment tapes. Both channels now even output
for PLAYBACK..
ü
Meters adjusted to even zero with symmetric input with Volt
meter, O-Scope and w/ STL and TEAC MTT-257H calibration /
alignment tapes. Both channels now even output
for PLAYBACK.
ü
Both Internal Record amplifier channels adjusted with Volt
meter, O-Scope and sine-wave generators and
'pink / white noise sources', however we were not able to get
great recordings. The left channel is often 'low / and distorted' on
'Recording' (sounds fine as a 'PLAYBACK' deck).
ü
Pinch roller and heads all in GREAT condition!!!
ü
Speed adjusted to 100% accuracy BOTH
directions, with with TEAC MTT-257H 1kHz factory calibration tape (meaning
1kHz calibration tape plays back at 1000Hz +/- 1
Hz)
ü
Pinch roller re-surfaced, and in GREAT condition!!!
ü
Tape Counter works well
ü
Speed adjusted internally to 100% accuracy with 1kHz factory
test tape (meaning 1kHz calibration tape plays back at 1000Hz
+/- 1Hz) (utilized TEAC MTT-257H)
ü
Floor noise measured at -60dBm
So again, this deck was ultimately passed as a 'Playback' deck.
Total technician time to restore
~22++ HOURS!
(YES, OUCH!) ____________________________
This deck is the commensurate deck for other Marantz
components such as the Marantz Escotec SC-7, SC-8, SC-9, SC-500 SC-2000
Pre-Amps, the SM-8, SM-500DC, SM-2000 Power Amps, EQ-20 Graphic
Equalizer, PM-8, PM-450 or PM-730 Integrated amps, ST-500 Tuner and many
others. I sold all of those components when they were new for a Marantz
dealer. If you're building that system (or already have most of that

adjustable tension. We removed the originals clutch pads,
fabricated new ones, installed and re-adjusted the tension
springs so now those functions perform properly (this
operation took over 5 hours so resolve).

*Ok,
so here's the deal on our 'As-Is' / 'As-Found' / 'For Restoration' units.
The prices are firm and are more based from their 'pre-processed parts value'.
We are offering these “As-Is” units simply
because they’re below our threshold of time-vs-effort-ROI at the time of
posting. Any less than our published price and we'll
go ahead and process them as "parts" and remove from sale or re-slate for future
restoration by us as time allows. At these
values / prices, no more photos or testing will be done by us.
Most or all of the following
applies to us as well, EVERYTIME we start the refurb / service process on a
unit. While we may sometimes (usually) state what
functions / condition we observed at the time of testing, it is in no way a
declaration of warranty (meaning; “we may have missed some $%#*”).
The existing condition we observed and
documented is also no guarantee of ultimate viability following further service
efforts. It is only offered 'As-Is', without our
normal *warranty and we won't have the
time resources to 'improve' it in anyway. The
existing condition we observed and documented is also not necessarily indicative
of the entire cosmetic / operational condition associated with a unit (there’s
probably issues we didn’t or couldn’t see at the time).
Restoring / refurbishing
'vintage / used' units properly is typically not an 'easy' process and if you
are 'not' a technician or will be disappointed if a unit does not come all the
way through to fruition, then you should probably purchase a unit that has
already been restored to 'working' condition. If
you are not a technician and do not understand the potential dangers of working
with electronic / electrical units, then DO NOT ATTEMPT repair / restoration /
further service or even open a unit up. The voltages
inside these unit can kill you and it will hurt the entire time you are dying!!!
Units should probably not be ‘powered up’ or
used until, at least, a cursory check by qualified personnel has been done.
Parts to restore / refurbish
/ service or 'further improve' the unit may or may not be readily available
(most parts can be sourced). Parts / units may
or may not respond positively to further repairs (you might blow something up).
Units may or may not have original parts. They may have missing, damaged,
modified, dangerous / outdated parts etc. (most will not).
Units may have evidence of past ‘non-factory’, incorrect, uncompleted,
shoddy or dangerous repairs (most will not).
These units are NOT intended
for someone looking for a 'working' unit or thinks you can simply 'install a new
belt', spray in some contact cleaner or change a light bulb and have a working
component. It typically requires 4-18 hours to
bring most units / vintage components back to a decent level of function and
utility for the 'long haul'.
The pack / ship will be the
same as for our 'fully restored' components so the reduced price of the "As-Is"
unit has NO BEARING on the cost to pack and ship (which is typically somewhere
between $45-$85 but can vary up or down from that range). shipped to most of the
lower 48 states. Extreme Southern, North Eastern, or North Western locales will
be slightly more.
Bottom line; If you’re not up
for the challenge either due to ‘lacking skill sets’ or ‘lacking funds’ to hire
the work done, and need a unit to be more than a ‘shelf display’, then I would
pursue a unit / component that has already been PROPERLY restored / refurbished
/ service with a ‘clean bill of health’. This goes for most of the units that
are for sale on on-line Auctions and Classified ads. Occasionally there will be
a unit ‘up for auction’ or on a classified ad that really has been service
properly, but they’re generally a ‘single digit percentage’ of what’s out there
available for sale.

AKAI AUTO-REVERSE
CASSETTE TAPE DECK
AKAI GXC-730D With 'AUTO-REVERSE' AND DOLBY NR
and REAL "VU" METERS #...9379 Circa early 1976-79 Made in Japan
SOLD 11/15/2021 SHIPPING TO STANLEY IN NEVADA
Original issues observed (mostly the
issues common with all 40 year old tape decks):
"power switch not working correctly, broken eject switch lever,
sluggish fast wind, noisy internal record switches, noisy level
controls, PB and REC levels low and un-matched, clutches
slipping way too much to be usable, L-Channel Bias way out.
Pinch rollers have un-even wear. Missing one input level knob."
ü
Our technician has completely and EXTENSIVELY gone through and
'Certified' this unit which involves complete disassembly of
the transport (not an easy task on this table), cleaning inside
and out, COMPLETELY DISASSEMBLING, cleaning and re-lubricating
all internal mechanisms and the balance of efforts listed below.
ü
Heads inspected for excessive wear (obviously we do this 'early
on' as 'excessive' wear will usually negate any further
restoration work, although as these are 'GX'
heads, it would be pretty hard to put much 'wear' on them).
These have virtually NO visible wear to them.
ü
Internal DC power supply tested
ü
Capstan motor
disassembled, cleaned and
re-lubed.

ü
Both Flywheel belt surfaces solvent
cleaned

ü
Bronze
Flywheel bushings solvent cleaned
ü
Both
Flywheel thrust pads cleaned
ü
Capstan burnished
ü
Reel drive
tires (7 IN ALL!!!)
replaced and / or reconditioned for trouble-free service.
(These are actually much more important to replace on this deck
(and most) than the belts. Without these, the deck won't fast
wind very well, and will likely 'eat tapes' as the 'take-up'
reel won't turn properly)
ü
New
internal Capstan Drive
belt (#FRM9.2) installed for trouble-free service.
(so this operation required extensive effort. The belts that
came in the so called "correct kit" currently available for the
Akai GXC-730D, proved to cause incorrect speed in two different
decks. We were then forced to find new belts that by 'trial and
error' allowed enough 'traction' and the most speed accuracy. In
fact, none of the belts in the 'official kit' that is currently
available for an Akai GXC-730D allowed the deck to operate at
anything resembling correct speed when tested on a frequency
counter with factory test tapes!)
ü
New
Counter belt (#.041) installed
as well as 'spindle' belt #029.
ü
Both hub spindles
clutches were slipping
and / or causing 'chatter'. Both were disassembled, shims added,
compression springs adjusted, pads and plates re-surfaced, lubed
where necessary and re-installed. (This was by far one of the
more time consuming aspects to restoring this deck!)
ü
Replaced broken
Eject paddle button from another GXC-730D donor unit
ü
Replaced
non-repairable Power switch assembly from another GXC-730D donor
unit
ü
Replaced missing
input level knob from another GXC-730D donor unit (some surface
scratches to the replacement knob)
ü
Rubber pinch rollers have been reconditioned
ü
Tape well door pins re-aligned / re-worked / repaired
ü
Heads have been cleaned and de-magnetized as well as the entire
transport.
ü
Head alignments and azimuth checked and adjusted as necessary
for 'peak performance' with O-Scope. As it's
an 'Auto-Reverse' deck, these adjustments are required
separately FOR BOTH DIRECTIONS!
ü
All internal pots, switches and controls cleaned and tested for
noise-free function.
ü
Head swivel for
Auto-Reverse disassembled, cleaned and lubed as it was stiff to
move (this was one of the more time consuming operations for
this deck).
ü
Both d'arsonoval
VU meters
static adjusted, tested and working
fine.
ü
Both
VU meter illumination
lamps replaced w/ #25-445 6.3V / 250mA.
ü
Both
VU Direction illumination
lamps replaced w/ 4 new bulbs.
ü
Both hub spindles NOW
in perfect alignment.
ü
FF, REW, & Play transport functions all test perfectly and
controls tested for positive / accurate responsive.
ü
Heads in great shape as well, with many years of performance
left in them and head alignment / azimuth has been checked for
peak performance.
ü
Playback meters zero
adjusted
'electronically' with factory test tone tape.
ü
Tape Counter Function tested
ü
Pinch roller and heads all in GREAT condition!!!
ü
Floor noise tested to -60dBm with empty shell
tape
ü
Speed tested to
98%
accuracy with 1kHz factory test tape (meaning 1kHz calibration
tape plays back at 980 Hz +/- 1Hz)
Only issue still remaining is that "Fast
Wind"
will slow more than typical as it nears completion of a side.
This cannot be improved anymore, and still does an adequate job.
ü
Deck has had just over 23 hours of
restoration work done.
Face is made of beautiful brushed aluminum, and overall the deck
is in great cosmetic condition.
One of the input level knobs has a few scuffs as mentioned above. Following the extensive
restoration, we did 'test recordings' of a 'ddd' CD on
2 tapes; Maxell Normal Bias, TDK 'SA'
High Bias, and Maxell 'XL-II' High Bias.
We found that both the "Maxell's" performed VERY well on this particular deck.
ü
Plays
great and records well
with 1kHz,
recorded 0dB playing back @ L=-2dB & R=-2dB on Maxell
UDXL-II tapes. With DDD CD we
experienced ~ -3 to -4dB, but great, overall sonics! (we
really put them through the paces, testing both with well mixed,
recently recorded CD material and CD recorded / factory test
tones looking for correct head Azimuth and speed accuracy).
ü Recording
tests performed with Maxell Normal Bias and Maxell
High-Bias UDXL-II (Gold / Black) Tapes. Here’s
the results;
Maxell UDXL-II: 1KhZ
with Dolby & CrO2 position @ 0dB = -2dB L & -2dB R with
virtually no
artifacts
Maxell UDXL-II: 1KhZ
W/O Dolby & CrO2 position @ 0dB = -2dB L & -2dB R with
virtually no
artifacts
Maxell UDXL-II: 1KhZ
with Dolby &
Normal
position @ 0dB = -2.5dB L & -3dB R with virtually no
artifacts
Maxell UDXL-II: 1KhZ
W/O Dolby & Normal position @ 0dB = -2.5dB L & -2dB R with
virtually no
artifacts Recorded program from "ddd" source @ 0dB sounds great
as well. It's nice recording on a deck that's 'dialed in'
properly)

- Akai's A.D.R. (automatic distortion
reduction) changes the recording equalizer characteristics
according to the signal level of a certain frequency band to
achieve low distortion over an extended frequency range. -
Auto-Limiter (if selected) to limit 'over /
peaks' on 'high energy' recordings. Great when recording in
'Live' situations. - Rear located, adjustable 'Bias / Recording Levels' (don't mess
with these without the proper test / calibration gear) - Tape Type selector for Normal, Fe-CO2,

There's just something about the feel of 'original piano key'
tape transports. This one especially has a
great "feel" to it. Like you're engaging some 'huge' mechanism
internally. The 'Auto-Reverse' is very 'precise' in it's motion. Again, we have completely refurbished and thoroughly tested this
deck, with multiple recording tests (as stated previously).
Cosmetically, other than the knob with scuffs
in it, it's condition! Also great for

____________________________
The Teac A-510 / A-500 with 'Dolby NR and IC Logic Transport',
Stereo Cassette Tape Deck. Great deck for doing tape transfers
if your tapes were recorded with no NR or with "Dolby B"
or for making some awesome 'new' recordings or 'mix tapes' (hey,
it's 'the thing' again).
This deck is a pleasure to use, and has a great 'feel' due to
it's size and transport function. As far as cosmetics,
it's BEAUTIFUL. Was taken very good care of before it came to
us, and is even more astounding now. Very impressive looking
deck.
Teac A-510 Features include:
- "Soft touch / IC LOGIC control" tape transport (allows you to
switch between 'Fast Wind' or 'Play' modes without pressing
'Stop' w/ no fear of 'spilling / dumping tape') - Selector for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV)
Tape Type - 3-Position Selector for Tape Equalization for Normal (EX / I),
CrO2 (SX / II) & Metal (ZX / IV) Tape Type on playback - Dual Fluorescent VU Level Meters - Analog Tape counter
- Variable Output Level control (one of the most
important features on a deck in our opinion) - Dolby B NR - Record Muting - Real 'Potentiometer' Record level controls that are 'gear
coupled' (meaning when you turn one, the other one responds as
well. They can be turned independently for 'fine adjustment' as
they're 'clutch coupled' as well) - Memory Stop for counter - Dual, Front mounted, 1/4", Microphone Jacks - Front mounted, 1/4", Stereo Headphone jack - RCA and DIN I/O's on rear panel - Timer Play / Record function. (IMPORTANT NOTE ABOUT 'TIMER
SWITCH' ON THIS DECK. If the 'Timer' switch is in any position
other than "OFF", and the tape plays thru to 'Auto-Stop', then
no other function on the deck will commence until the 'Timer'
switch is turnted to "Off". That is what the 'sticker' on the
top of the unit indicates (and we found to be the case)) - Multi-pin port on rear panel for optional wired remote, TEAC
RC-90 (remote not included)
Teac A-510Specifications:

~90 Seconds for C-60 tape Again, we have completely cleaned, refurbished / serviced and
thoroughly tested this Teac A-510 cassette tape deck. Great for transferring your no NR or Dolby B NR encoded tape
collection to CD, Hard-drive or MP3 especially with the 'Tape EQ'
selector for 'fine tuning' older tapes. Built very well!
Again, not going to win any beauty contests, but
performs decently. Due to it's size, overall
feel, the 'input controls' and the 'transport control' this deck
really is a blast to use. Comes with an 'e-copy / pdf download'
of the TEAC A-510-MKII owners / users /
instruction manual, and the TEAC A-510 / A-500 cassette tape deck service manual if
the purchaser desires. Measures 18.6" wide x 13.5" deep x 7.25"
tall and weighs a VERY HEAVY 24 lbs
unpacked. Just in-case you 'too casually' read past that last
little bit, IT'S A TWENTY-FOUR POUND CASSETTE DECK!

NAKAMICHI is known for 'Cassette Decks', but they were expensive
when new, so we don't see a lot floating around on the secondary
market, so when we do, it's always a treat. Here's a NAK BX-1, which
following all of the above listed service work, is READY TO GO!
Nakamichi BX-1 Features:
-
2-Motors
-
IC Logic, 'Silent Mechanism' Tape Transport controls (allows you to
switch between 'Fast Wind' or 'Play' modes without pressing 'Stop'
w/ no fear of 'spilling / dumping tape')
- 2 Motor Transport (DC Servo motors. One for
Capstan drive and one for Reel drive)
- Dolby B Noise Reduction

tape types
- Dual, LED level meters
- Analog Tape Counter
- Memory tied to the counter for 'Zero Stop'
- Front-mounted 1/4" stereo headphone jack
- Timer option for Play or Record start

Fast Wind Time: ~80-90 Seconds for
C-60 tape
Again, as mentioned above, our tech has gone through it completely
cleaning all parts, controls and tape mechanism. As mentioned, the
power supply was originally not functioning correctly, so before
restoration could commence, we replaced a faulty voltage regulator.
We also checked, cleaned, reconditioned and / or replaced rubber
components. We completely de-magnetized the heads and transport.
Capstan motor speed adjusted to exact spec! Tape speed
re-adjusted to 100% accuracy, ie; 1 kHz = 1 kHz! And with it's
service work completed the deck records incredibly well and plays
back utilizing Maxell UD XL-II tapes at -2dB
down!
Cosmetically there are
numerous scratches to the black paint, on the top
and sides of the sheet metal housing.
Probably from someone setting a unit on top of it that didn't have
feet and sliding it across shelves. Of
course you only notice that when looking 'down from above' the deck,
so in a rack, wouldn't be seen. Overall, the deck looks good and
sounds great! Great for transferring your tape collection to CD,
Hard-drive or MP3. Plays and Records well. Very clean and usable
deck! Includes a pdf / e-copy download of the Nakamichi BX-1 owners
/ users / instruction manual. Measures 17" w X 10" d X 4.25" h and
unpacked weight is 13 lbs. Comes with our 90 day limited warranty.

Original issues observed (mostly the
issues common with all 40 year old tape decks):
"No play movement due to perished drive belt,
so due to that, unable to test further until that was addressed"
ü
Our technician has completely and EXTENSIVELY gone through and
'Certified' this unit which involves total disassembly of the
transport, cleaning inside and out, COMPLETELY DISASSEMBLING, cleaning
and re-lubricating all internal mechanisms and the balance of efforts
listed below.
ü
Heads inspected for excessive wear (obviously we do this 'early on' as
'excessive' wear will usually negate any further restoration
work).
ü

switches required disassembly and removal of front fluorescent display
to access for cleaning. This step alone took 2 hours)
ü
All Fluorescent displays and LED's working fine.
ü
Both hub spindles in perfect alignment
ü
FF, REW, & Play transport functions all test perfectly and controls
tested for 'positive / accurate' responsive.
ü
Heads in great shape as well, with many years of performance left in
them
ü
Heads have been cleaned and de-magnetized as well as the entire
transport.
ü
Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH
directions for 'peak performance' with O-Scope and w/ STL and TEAC
MTT-257H calibration / alignment tapes. Both channels now even output.
ü
Both Internal playback amplifier channels adjusted with Volt meter,
O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both

channels now even output.
ü
Pinch roller and heads all in GREAT condition!!!
ü
Speed adjusted to 100% accuracy BOTH directions, with with TEAC MTT-257H
1kHz factory calibration tape (meaning 1kHz calibration tape plays back
at 1000Hz +/- 1 Hz. The service manual allows for an
error range of +/- 23Hz! Yuck!!!)
ü
Pinch roller re-surfaced, and in GREAT condition!!!
ü
Playback meters zero with factory test tone tape.

ü
Floor noise measured at -74dBu
Following service / fine tuning;
ü Recording
tests performed with Maxell
High-Bias UDXL-II (Gold / Black) Tapes.
Here’s the results;
Maxell UDXL-II: 1KhZ
with No NR @ 0dB; L= 0dB & R= 0dB R with
virtually no
artifacts
Maxell UDXL-II: PN
with No NR @ 0dB; L= -1dB & R= -1dB R
Recorded program from "ddd" source @ 0dB sounds great
as well. It's nice recording on a deck that's 'dialed in'
properly)
Following restoration, during one of our extensive 'post tests' we
discovered that the deck was not erasing consistently. We eventually
discovered that the erase head had it's own mechanism to move it, which
was an originally 'lubricated' parts. Well, just as all 30+ year old
lube gels and stiffens up, so had that. We then disassembled the erase
head pivot arm, solvent cleaned it, lubricated it and re-assembled
mechanism. Worked as intended then. This process alone added 2.5 hours
to restoration. This was a mechanism somewhat different than we come
across in most decks.
Total technician time to restore ~15.5
HOURS!

- Three-Heads!
- Super Hard, Permalloy' PB / REC heads
- 2 Motors (one for capstan drive and a separate
motor for reel drive)
- Adjustable Fine Bias Control for Recording allows
you to really 'dial in' the sonic qualities for each different tape
formulation (brand / model) you may want to use
- IC logic "touch-control" tape transport with motor driven 'cam control
mechanism' (allows you to switch between 'Fast Wind' or 'Play' modes
without pressing 'Stop' w/ no fear of 'spilling / dumping tape')
- Dolby-B & dbx noise reduction built-in for recording and
playback
- dbx 'Disc' decoder. Allows you to get "dbx"
benefits from encoded LP's (I've had this on my personal deck for almost
4 decades!)
- Parametric EQ that can be utilized to imprint EQ characteristics to
tape. Handy if you wish to play tapes on another system that needs
certain frequencies accentuated or attenuated.
- TapeType / EQ selector for Normal, CrO2 & Metal tape
- Variable Output level control
- Fluorescent display / VU signal level Indicators

Erase, Record and separate Play (most decks are "2-head" and use a
combined Play / Record head. Separate Record and Play heads allow for
nearly instant monitoring of recording by listening to the actual signal
just recorded on the tape, not just the 'source signal' coming into the
deck. Great for making level, EQ and Fine Bias adjustments. Also allows
our tech to really 'dial in' a deck from a performance standpoint).
Motors: 2. 1 for capstan drive and one for reel drive. Both are
DC
Freq Response w/ Dolby OFF: w/ Metal; 20-20,000 Hz +/- 3dB

Again, we have completely refurbished and thoroughly tested this deck.
From a 'feature' standpoint, IT'S LOADED!!!
Cosmetically, it's in fabulous condition with, other
than some very light scratches on the rear part of the top cover /
bonnet, there's really nothing to mention.
Great deck for just about any system. Also great for transferring your
tape collection to CD, Hard-drive or MP3. Includes an 'e-copy / pdf

NAKAMICHI is known for 'Cassette Decks', but they were expensive when
new, so we don't see a lot floating around on the secondary market, so
when we do, it's always a treat. Here's a NAK CR-3A, "3-Head" deck 'made
for recording'! And following all of the above listed service work, it's
READY TO GO!
Nakamichi CR-3A Features:

that the deck can 'manage' the entire tape path.
- IC
Logic, 'Silent Mechanism' Tape Transport controls
- 2 Motor Transport
- Dolby B & C Noise Reduction
- Tape type selector for Normal / Chrome & Metal tapes
- Fine Bias Tuning (really becomes useful coupled with the "3-head"
design for 'fine tuning' recordings around different tape types)
- 2-Position Tape Equalization to optimize playback of different tape
types
- Auto-Slack mechanism (takes up slack in tape upon closing the cassette
well door)
- 'One Touch' Rec/Pause
- Record Mute
- Built-in MPX filter for killing the 19kHz pilot tone in FM
transmissions
- Variable Output Level control (one of the most important features on a
deck in our opinion)
- Dual, LED level meters
- Memory tied to the counter
- Front-mounted 1/4" stereo headphone jack
- Timer option for Play or Record start
- System' remote port for tying in with other, compatible Nakamichi
components

Again, as
mentioned above, our tech has gone through it completely cleaning all
parts, controls and tape mechanism. We also checked, cleaned,
reconditioned and / or replaced rubber components. We completely
de-magnetized the heads and transport. Capstan motor speed adjusted to
exact spec! Tape speed re-adjusted to 100% accuracy, ie; 1 kHz =
1 kHz! And with it's service work completed the deck records incredibly
well and plays back utilizing Maxell UDXL-II
tapes at a respectable
-4- -5dB down. The
looks and sounds great! Only issue worth
mentioning is that the 'supply' reel is missing it's small, black e-clip
cover so you see the silver e-clip if you're looking close enough.
Great for transferring your tape collection to CD, Hard-drive or
MP3. Plays and Records extremely well. Very clean deck and usable deck!
Includes a pdf / e-copy download of the Nakamichi CR-3A owners / users /

Our technician has completely and EXTENSIVELY gone through and
'Certified' this unit which involves complete disassembly of
the transport (not an easy task on this table), cleaning inside
and out, COMPLETELY DISASSEMBLING, cleaning and re-lubricating
all internal mechanisms and the balance of efforts listed below.
ü
Heads
inspected for excessive wear (obviously we do this 'early on' as
'excessive' wear will usually negate any further restoration
work, although as these are 'GX' heads, it would
be pretty hard to put much 'wear' on them). These have virtually NO visible wear to them.
ü
Internal DC power supply tested
ü
Capstan motor disassembled, cleaned and
re-lubed.

ü
Both Flywheel 'belt surfaces' solvent cleaned

ü
Bronze
Flywheel bushings solvent cleaned
ü
Both
Flywheel thrust pads cleaned
ü
Capstan burnished
ü
'Reel
drive' tires (7 IN ALL!!!) reconditioned for
trouble-free service.
(These are actually much more important to replace on this deck (and
most) than the belts. Without these, the deck won't fast wind very
well, and will likely 'eat tapes' as the 'take-up' reel won't turn
properly)
ü
New
internal Capstan Drive
belt (#FRM9.2) installed for trouble-free service.
(so this operation required extensive effort. The belts that
came in the so called "correct kit" currently available for the
Akai GXC-730D, proved to cause incorrect speed in two different
decks. We were then forced to find new belts that by 'trial and
error' allowed enough 'traction' and the most speed accuracy. In
fact, none of the belts in the 'official kit' that is currently
available for an Akai GXC-730D allowed the deck to operate at
anything resembling correct speed when tested on a frequency
counter with factory test tapes!)
ü
New
'Counter' belt (#.041) installed
as well as 'spindle' belt #029.
ü
'Non-locking' 'Pause' control disassembled, cleaned and re-lubed
ü
Rubber pinch rollers have been reconditioned
ü
Tape well door 'eject' springs re-worked / repaired
ü
Heads have been cleaned and de-magnetized as well as the entire
transport.
ü
Head alignments and azimuth checked and adjusted as necessary
for 'peak performance' with O-Scope
ü
All internal pots, switches and controls cleaned and tested for
noise-free function.
ü
Both d'arsonoval
VU meters
'static adjusted', tested and working fine.
ü
Both
VU meter illumination
lamps replaced.
ü
Both hub spindles in perfect alignment.
ü
FF, REW, & Play transport functions all test perfectly and
controls tested for 'positive / accurate' responsive.
ü
Heads in great shape as well, with many years of performance
left in them and head alignment / azimuth has been checked for
peak performance.
ü
Replaced 'Erase Head', reed switch with OEM
from another of the same model (very difficult to deduce and
locate as source of issue with deck 'not erasing' correctly)

ü
Playback meters zero adjusted
'electronically' with factory test tone tape.
ü
Tape Counter Function tested
ü
Plays perfectly and records well with 1kHz,
recorded 0dB playing back @ L=-2dB & R=-3.5dB (between
TDK and Maxell tapes). With DDD CD we
experienced ~ -5 to -6dB, but great, overall sonics! (we
really put them through the paces, testing both with well mixed,
recently recorded CD material and CD recorded / factory test
tones looking for correct head Azimuth and speed accuracy).
ü
Pinch roller and heads all in GREAT condition!!!
ü
Floor noise tested to -60dBm with empty shell
tape
ü
Speed tested to 98% accuracy with 1kHz factory test tape
(meaning 1kHz calibration tape plays back at
980Hz +/- 1Hz)
Only issue still remaining is that "Rewind"
is noisy on some tapes as it nears completion.
ü
Deck has had just over 18.5 hours of
restoration work done.
Face is made of beautiful brushed aluminum, and overall the deck
is in NEW cosmetic condition. Following the extensive
restoration, we did 'test recordings' of a 'ddd' CD on 6 tapes;
Sony Normal Bias, Fuji Normal Bias, TDK Normal Bias, Maxell
Normal Bias, TDK 'SA' High Bias, and Maxell 'XL-II' High Bias.
We found that for Normal and High Bias, of those tapes tested,
both the "Maxells" performed VERY well on this particular deck.
Total technician time to restore
~18.5 HOURS!

Handsomely designed, and classic looking Akai
GXC-730D, Auto-Reverse cassette tape deck.
Features Piano-Key
transport, Auto-Reverse,
& Dolby B. Great deck for most systems
and uses. One of the 'Biggest' cassette decks ever made.
AKAI GCX-730D
Features include:
- 3-Mode Auto-Reverse ('Manual' reverse as
well of course)
- Huge drive Motor
- Classic 'Piano Key' transport w/ Solenoid
assist results in 'Soft Touch operation
- Dolby noise reduction built-in for recording and playback
- Akai's A.D.R. (automatic distortion
reduction) changes the recording equalizer characteristics
according to the signal level of a certain frequency band to
achieve low distortion over an extended frequency range.
- Auto-Limiter (if selected) to limit 'over /
peaks' on 'high energy' recordings. Great when recording in
'Live' situations.
- Tape Type selector for Normal, Fe-CO2, &
CrO2 tape
- Dual, Large "VU" signal level meters
-
"Peak" LED level indicator that kicks in at
+7dB
- Manual Record Level with independent L&R control
- Variable Output Level control (one of the most important features on a
deck in our opinion.
Allows you to
match volume level of other sources, allows adjustment for
'best' pre-amp input to avoid distortion, allows you to change
the volume of the deck if you have it located remotely from the
pre-amp / receiver as I do, and many other applications)
- Dual front mounted 1/4" mic input jacks
- Front mounted Stereo Headphone jack
- Analog Tape Counter w/ "Memory Stop" -True "WORLD AC POWER"™ allows unit to be operated on 50 or 60 Hz AC and
will select voltages from 110v, 120v, 220v and 240 volts AC input.

on C-60 Tapes (again, does have the above
mentioned 'slowing' characteristic near the 'end' of FF
operation)
There's just something about the feel of 'original piano key'
tape transports. This one especially has a
great "feel" to it. Like you're engaging some 'huge' mechanism
internally. The 'Auto-Reverse' is very 'precise' in it's motion.
Again, we have completely refurbished and thoroughly tested this
deck, with multiple recording tests (as stated previously).
Cosmetically, it's in essentially NEW condition! Also great for transferring
your tape collection to CD, Hard-drive or MP3. Includes original
box and packing. Comes with an 'e-copy' / pdf

The
Teac CX-650R, Auto-Reverse with 'Bi-Directional Recording', Stereo Cassette Tape
Deck. Great deck for doing your tape transfers if your tapes were recorded with
no NR or with "Dolby B" or for making some awesome 'new' recordings or 'mix
tapes' (hey, it's 'the thing' again). This deck is a pleasure to use, and has a
great 'feel' due to it's size and transport function.
As far as cosmetics, it's BEAUTIFUL. Was taken very good care of before it came
to us, and is even more astounding now. The deck and the wood grain case could
convince you that time had rolled back almost 40 years, and you were seeing it
at the original store's retail display.
Teac CX-650R Features include: - Heavy duty transport featuring 'oversized' capstan motor, and VERY large,
'asymmetrical' flywheels - Triple-Mode Auto-Reverse, with 'Bi-Directional' Recording (not just 'A' side
recording!) - "Soft touch-control" tape transport - Selector for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV) Tape Type - 3-Position Selector for Tape Equalization for Normal (EX / I), CrO2 (SX / II)
& Metal (ZX / IV) Tape Type on playback - Dual Analog VU Level Meters - Analog counter - Built-in MPX filter for killing the 19kHz pilot tone in FM transmissions - Variable Output Level control (one of the most important features on a deck in
our opinion) - Dolby B NR - Record Muting - 'Auto-Space' records a 4-second space prior to 'stop' when engaged. - Real 'Potentiometer' Record level controls that are 'gear coupled' (meaning
when you turn one, the other one responds as well. They can be turned
independently for 'fine adjustment' as they're 'clutch coupled' as well) - Memory Stop / Repeat for counter - Dual, Front mounted, 1/4", Microphone Jacks - Front mounted, 1/4", Stereo Headphone jack - Timer Play / Record function. - Multi-pin port on rear panel for optional wired remote, TEAC RC-100 (remote
not included)

Hard-drive or MP3 especially with the 'Tape EQ' selector for 'fine tuning' older
tapes. Built very well!

is a blast to use. Comes with an 'e-copy / pdf download' of the TEAC CX-650R

VERY CLEAN & LIKE NEW deck inside before we started our service
work)
ü
AC voltage set for 'North American' use, and Internal DC power
supply tested to correct Voltages before any work commenced

ü
Main Drive and Counter belts inspected

ü
Rubber pinch rollers have been reconditioned
ü
One VERY important note about this
deck. The spindles are 'gear driven' which means that it should
WAY OUTLAST most other decks that utilize standard, rubber
'idler tires' for reel activation
(everyone thinks that 'belts' are all you need to replace to
make a cassette deck work. While belts are important, it's
almost always the 'idler tire' that is the "Achilles
Heel" of cassette decks and causes the VAST majority of
cassette deck problems).

Heads have been cleaned and de-magnetized as well as the entire

AMAZINGLY well w/ following results;
1kHz recorded @ 0dB with Dolby C engaged on Maxell XL-II (High
bias) tapes plays back @ -2 dB L&R.
Full Bandwidth 'White Noise' recorded @ 0dB
w/o NR engaged
on Maxell XL-II (High bias) tapes plays back @

____________________________
This Pioneer CT-M6R is a well built and designed deck and is a
BLAST TO USE! (I personally used it extensively following it's
refurb / service). It's super quality in design and build, and
it's loaded. It's a 'Double Auto-Reverse', with 'Bi-Directional'
Recording, AND it's a 6 tape changer that can record up to 9
HOURS CONTINUOUSLY!
This is an incredible deck for performance and IT'S LOADED! It
would be at home in any audio system.
Pioneer CT-M6R Features include:
- HX-PRO (Extended Head-Room Recording) (One
of the BEST features of 'modern / recent' cassette decks)
- 6 Cassette Tape Changer
- Dolby B & C Noise Reduction built-in
- Relay Recording. This means that you can record all 6 tapes on
both sides for 9 hours of continuous recording time w' standard
90 minute tapes
- IC Logic "touch-control" tape transport on both decks
- Super-quality tape heads- "MS" Music Search" cuing
- OTR (One Touch Recording and Pause)
- Auto-Selector for Normal, CrO2 & Metal Tape Type
- Full fluorescent readout screen
- Dual fluorescent signal level meters
- Multi-Mode, Digital tape counter for either tape well. Gives
"Standard" count or "Real Time" and Time Remaining
- "All Rewind" (this ends up being a VERY handy feature. If you
have a bunch of tapes that were stopped in random spots, just
put them all in, and press "All Rewind". It will automatically
go thru each and re-wind either Side A or B, depending on how
you load the tapes)
- Record Level control
- Record Mute function
- Timer Play / Record / Off selector
- 1/4" Stereo Headphone jack
- Wireless Remote Control (INCLUDED)
- "CD Synchro" for other Pioneer compatible gear
- AND LIKELY MORE THAT WE DIDN'T LIST

Only the forth cassette changer we've had since I sold an Aiwa
changer when new around 1984. You would likely be the only 'kid
on the block' with one of these.
Also great for transferring your tape collection to CD,
Hard-drive or MP3. As it can do up to 9 hours of continuous
recording, think of the possibilities. Built very well! Looks
like new and sounds great. Deck includes a copy of original
owners manual. Measures 16.5" wide x 14.5" deep x 5.5" tall and

GEAR DRIVEN SPINDLES - NO IDLER TIRES!!! #...747A Circa early 1986-88 Made in Japan
SOLD 4/22/20 SHIPPING TO SHADRACH IN CANADA
ü
Our technician has completely and EXTENSIVELY gone through and
'Certified' this unit which involves total disassembly of
the transport, cleaning inside and out, COMPLETELY
DISASSEMBLING, cleaning and re-lubricating all internal
mechanisms and the balance of efforts listed below.
ü
Heads inspected for excessive wear (obviously we do this 'early
on' as 'excessive' wear will usually negate any further
restoration work).
ü
Spindles are GEAR DRIVEN which means NO idler tires / wheels to
glaze over, crack and mis-behave with none of the typically
associated ills.
ü
Counter belt
- NO counter
belt. It's GEAR DRIVEN!!!
ü
Main Capstan / Flywheel belt reconditioned.
ü
Rubber pinch roller mechanism bushings & axles cleaned of old
lube, reconditioned and re-lubed.
ü
Capstans cleaned /
burnished
ü
All internal pots, switches and controls cleaned and tested for
noise-free function.
ü
All Fluorescent displays and LED's working fine.
ü
Both hub spindles in perfect alignment and
end locks intact and staying put.
ü
FF, REW, & Play transport functions all test perfectly and
controls tested for 'positive / accurate' responsive.
ü
Heads in great shape as well, with many years of performance
left in them
ü
Heads have been cleaned and de-magnetized as well as the entire
transport.
ü
Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for
BOTH directions for 'peak performance' with O-Scope and w/ STL
and TEAC MTT-257H calibration / alignment tapes. Both channels
now even output.
ü
Both Internal playback amplifier channels adjusted with Volt
meter, O-Scope and w/ STL and TEAC MTT-257H calibration /
alignment tapes. Both channels now even output.
ü
Meters adjusted to even zero with symmetric input with Volt
meter, O-Scope and w/ STL and TEAC MTT-257H calibration /
alignment tapes. Both channels now even output.
ü
Both Internal Record amplifier channels adjusted with Volt
meter, O-Scope and sine-wave generators and
'pink / white noise sources'. Both channels now even
output.
ü
Pinch roller and heads all in GREAT condition!!!
ü
Speed adjusted to 100% accuracy BOTH
directions, with with TEAC MTT-257H 1kHz factory calibration tape (meaning
1kHz calibration tape plays back at 1000Hz +/- 1
Hz)
ü
Pinch roller re-surfaced, and in GREAT condition!!!
ü
Playback meters zero with factory test tone tape.
ü
Tape Counter and 'Memory' Function tested
ü
White Noise recorded @ 0dB w/ Dolby-C engaged = PB @ -2dB on
Maxell UDXL-II / High Bias tapes
ü
1kHz
Sine-wave recorded @ 0dB w/ Dolby-C engaged = PB @ -1.5dB
on Maxell UDXL-II / High Bias tapes
ü
'ddd' CD recorded recorded @ 0dB w/ Dolby-C engaged = PB @ ~ -1dB
on Maxell UDXL-II / High Bias tapes
ü
1kHz
Sine-wave recorded @ 0dB w/
*dbx
engaged = PB @ -1.5dB on Maxell UDXL-II
/ High Bias tapes.
ü
'ddd' CD recorded recorded @ +3dB w/
*dbx
engaged = PB @ ~ -6dB on Maxell UDXL-II
/ High Bias tapes So this is the one aspect of the deck that we were not able to
'practically' rectify. It's record and playback capability with
dbx NR engaged is about 9dB down. It probably needs it's 'dbx
chips' replaced, but beyond the scope of practicality for us and
this deck.
ü
Speed adjusted internally to 100% accuracy with 1kHz factory
test tape (meaning 1kHz calibration tape plays back at 1000Hz
+/- 1Hz) (utilized TEAC MTT-257H)

Again, we have completely refurbished and thoroughly tested this
deck. From a 'feature' standpoint, IT'S
LOADED!!! Again, though as mentioned earlier, it's "dbx" function is less
than typical. It is about 9dB down. It's still usable, but
you'll need to increase your volume substantially to play tapes
encoded with dbx. Cosmetically, it's in
fabulous
condition with really nothing to mention.
Great deck for just about any system. Also great for
transferring your tape collection to CD, Hard-drive or MP3.
Includes an 'e-copy / pdf download' of the
Luxman K-109 owners manual which is similar enough to be fairly
useful. Measures 17.3" wide x 12"

to -2 dB on Maxell UDXL-II / High Bias tapes
Bottom line is this deck sounds amazing for playback or recording
(always make sure you're playing back 'good quality' tape
recordings) Total technician time to restore
8+ HOURS!
(Tech note: This model deck is "VERY SERVICEABLE"
since it's in their 'Pro-Line'. (Only remaining issues would be that REW is a bit noisy when nearing
completion on most brands of tapes and Right output pot still a bit
noisy when manipulated) ____________________________
The
Tascam 133, Pro-Series, 2-SPEED, Stereo
Cassette Tape Deck. Great deck for a 'project recording studio' as a
'mastering deck' (utilizing the 'High Speed'). With an original MSRP of over $1500, this was one of Tascams most
expensive cassette decks ever. Of course also makes an
incredible 'home system' deck and of also a great deck for doing
your tape transfers if your tapes were recorded with no NR or with
"Dolby B". Think of making some awesome 'new' recordings or 'mix
tapes' (hey, it's 'the thing' again). This deck is a pleasure to
use, and has a great 'feel' due to it's size and transport function.
As this was made for 'video / radio' production
it limits frequency response to 15k (per FCC limits), but makes up
for it in robust build quality.
TASCAM 133 Features include:
- Two Speeds; 1 7/8 ips (normal) and 3.75 ips (HIGH Speed for best
recording quality)
-
Dolby B NR - Rear I/O RCA jacks for connecting external dbx (or other NR) unit - Heavy duty transport featuring 'oversized' capstan motor, and
large flywheel - "Soft touch / IC Logic
control" tape
transport - Triple Analog VU Level Meters -
Digital Tape counter - Variable Output Level control (one of the most important features on a
deck in our opinion.
Allows you to match
volume level of other sources, allows adjustment for 'best' pre-amp
input to avoid distortion, allows you to change the volume of the
deck if you have it located remotely from the pre-amp / receiver as
I do, and many other applications) - Real 'Potentiometer' Record level controls - Memory Stop / Repeat Play and for 'Rewind'
for counter - Dual, Front mounted, 1/4", Microphone Jacks - Front mounted, 1/4", Stereo Headphone jack w/
Level / volume control - Multi-pin port on rear panel for any optional dbx NR unit (not
included) - Multi-pin port on rear panel for optional wired remote, (Tascam
RC-133 remote not included)
TASCAM 133 Specifications:
Track format: 4
track / 3 channel Motors: 2x 1x DC 'Reel', & 1x FG Servo Controlled DC 'Capstan' Freq Response w/ Philips tape;
30Hz
to 15kHz +/- 3dB
@ 'High Speed' Wow & Flutter (WRMS):

Fast Wind time: <90sec
on C-60 Tapes) Again, we have completely cleaned, refurbished / serviced and
thoroughly tested this Tascam 133, 'PRO'
cassette tape deck. Makes fabulous recordings. Also great for transferring your no NR or
Dolby B NR encoded tape collection to CD, Hard-drive or MP3
especially with the 'Tape EQ' selector for 'fine tuning' older
tapes. Built very well! Due to it's size, overall feel, the 'input
controls' and the 'transport control' this deck really is a blast to
use. Would make a great '2-Track' deck to match
your Tascam 234 'Multi-Track' if you have one. Sorry, but we did not
get the rack ears so no covering over face plate ends on the sides.
Comes with an e-copy / pdf download of the Tascam 133 owners / user
/ instruction manual and the service manual if the purchaser
desires. Measures 19" wide x 13.5" deep x
5.75" tall and weighs a heavy 20 lbs unpacked. Includes our standard 90 day limited warranty.

Noise and 'ddd' CD's on Maxell 'XL-II' High Bias. We found that they
all performed VERY well on this particular deck
(and most decks). We did however find that the deck likes to
record at about -20dB on the meters, for
'smoother saturation' of tape (which is the
industry standard, we just like to 'push them'). Again, we
really didn't have a favorite, plus the deck has adjustable Bias
(although we left it 'centered' for our tests).
Total technician time to restore

____________________________
The
Akai GX-F60R, Auto-Reverse,
Stereo Cassette Tape Deck.
Akai has always been known as one of the top
manufacturers of 'tape decks', especially Reel to Reel decks, and
they bring that expertise to 'Cassette Decks' as well, especially
when it comes to 'motor technology'. Their cassette and 8-track
decks have some of the biggest motors. Great deck for doing your tape transfers
if your tapes were recorded with no NR or with "Dolby B"
or for making some awesome 'new' recordings or 'mix tapes' (hey,
it's 'the thing' again). This deck is a pleasure to use, and has a great
'feel' due to it's size and transport function.
As far as cosmetics, it's BEAUTIFUL. Just a couple little minor
scuffs / dings on the included, but originally optional wood grained
case (see photos above). Was taken very good care of
before it came to us, and is even more astounding now. The deck and
the wood grain case could convince you that time had rolled back
almost 40 years, and you were seeing it at the original store's
retail display.
AKAI GX-F60R
Features include:

perfectly and after adjustment, records AMAZINGLY
well at -1dB! on

(but 'top end' will not be as good as on CrO2). (Following
the extensive restoration,
we did 'test recordings' of a 'ddd' CD on 6
tapes; Sony HF Normal Bias -3dB, Fuji Normal Bias -2.5dB, TDK Normal Bias
-1.5dB, Maxell
Normal Bias, TDK 'SA' High Bias -2dB (didn't saturate as well as the
Maxell UDXL-II), and Maxell 'XL-II' High Bias. We
found that for Normal and High Bias, of those tapes tested, both "Maxells" performed well on this particular deck.
The Maxell's did however much 'outshine' the TDK's for being able to
'over saturate' on the levels. While doing the test recording's, it
became apparent that the recorded sound was fairly remarkable.

pinch rollers have been reconditioned
ü
One VERY
important note about this deck. The spindles are 'gear driven'
which means that it should WAY OUTLAST most other decks that
utilize standard, rubber 'idler tires' for reel activation
(everyone thinks that 'belts' are all you need to replace to
make a cassette deck work. While belts are important, it's
almost always the 'idler tire' that is the "Achilles
Heel" of cassette decks and causes the VAST majority of
cassette deck problems).

Heads have been cleaned and de-magnetized
as well as the entire transport.

____________________________
This Pioneer CT-M6R is
a well built and designed deck and is a BLAST
TO USE! (I personally used it
extensively following it's refurb / service). It's super
quality in design and build, and it's loaded. It's a
'Double Auto-Reverse',
with
'Bi-Directional' Recording, AND it's a 6 tape
changer that can record up to 9 HOURS CONTINUOUSLY!
This is an
incredible deck for performance and IT'S LOADED! It would be at home in any
audio system.
Pioneer CT-M6R Features
include:
- HX-PRO (Extended Head-Room Recording)
- 6 Cassette Tape Changer - Dolby B & C Noise Reduction built-in - Relay Recording. This means that you can record all
6 tapes on both sides for
9 hours of continuous recording time w' standard 90 minute
tapes - IC Logic "touch-control" tape transport on both decks - Super-quality tape heads- "MS" Music Search" cuing
- OTR (One Touch Recording and Pause) - Auto-Selector for Normal, CrO2 & Metal Tape Type
- Full fluorescent readout screen - Dual fluorescent signal
level meters - Multi-Mode, Digital tape counter for either tape well. Gives "Standard"
count or "Real Time" and Time Remaining
- "All Rewind" (this ends up being a VERY handy feature. If you
have a bunch of tapes that were stopped in random spots, just
put them all in, and press "All Rewind". It will automatically
go thru each and re-wind either Side A or B, depending on how
you load the tapes)
- Record Level control - Record Mute function - Timer Play / Record / Off selector - 1/4" Stereo Headphone jack
- Wireless Remote Control
(INCLUDED) - "CD Synchro" for other Pioneer compatible gear
- AND LIKELY MORE THAT WE DIDN'T LIST
Pioneer CT-M6R Specs:
Track format - 4 track / 2 channel
Heads - Super-Hard,
Permalloy for Recording and Playback head.
Ferrite for Erase head Motors -

This
Pioneer CT-M6R is an incredible deck and a rare one too.
Only the second cassette changer we've
had since I sold an Aiwa changer when
new around 1984. You would likely be the only
'kid on the block' with one
of these.
Also great
for transferring your tape collection to CD, Hard-drive or MP3.
As it can do up to 9 hours of continuous
recording, think of the possibilities. Built very
well! Looks like new and sounds great. Deck includes a copy of original
owners manual. Measures 16.5" wide x 14.5" deep x 5.5" tall and weighs
19 lbs unpacked. Comes with our 90 day limited warranty.

Did you know?
Technics;
The name Technics was introduced as a brand name for premium
loudspeakers marketed domestically by Matsushita in 1965. In 1969, they
introduced the SP-10, the first direct-drive turntable model for the
professional market, and in 1971 the SL-1100 for the consumer market.
The SL-1200 has since it's inception been the 'standard' of the industry
for DJ's around the world. Most of there turntables are of 'industry
standard' quality, even on the 'low-end' of the price scale, for most of
their model years.
Technics
was the first to introduce 'auto-reverse' (1972) into cassette decks
(some would say to the detriment of audio quality, but certainly 'handy'
in many applications) and 3-heads in a cassette deck (1973). In the late 1970's, Technics introduced what are
some of the currently most sought after reel to reel decks out there.
The Technics 1500 and 1700 series. They are overall 'amazing'! I am a HUGE fan of Technics gear, especially their cassette decks. I
worked for a Technics dealer in the early 1980's and loved to sell
Technics gear because, not only did I know it would perform splendidly
for most applications, it rarely came back with an issue. In fact, I
extend that opinion to today, now 30 years on, as if I have to place a
'blind bet' on an 'as-found' item either still functioning, or being not
far from it, I will go with Technics almost every time. Yamaha would
typically be my second choice followed by the other 'famous'
manufacturers a ways down the list. That's not to say 'Technics can do
no wrong', because like everyone, they built a few 'lemons', but overall
they do MOSTLY right.
