MIJ
SOLD 7/19/12 Our technician has
completely gone through this unit cleaning
everything including all switches (actually accessed
(requires 'splitting' the unit horizontally)
and fully
flooded), controls and contacts for quiet, positive operation.
Extra
attention is ALWAYS necessary on Sansui 990 / 9090 units to the 'Input
Selector'
and 'Dolby' switches, and they were completely disassembled, thoroughly
cleaned, burnished, had contacts 're-sprung' and tested (only about half
the 990's, 8080's and 9090's have input selector switches that will
respond to cleaning only). On this
unit, he actually bypassed the wafer portion that routes the dial light
current, and direct wired the lights to be lit constantly
(the
issue with the dial lights on Sansui 880 / 8080-DB / 990 / 9090-DB
series receivers is that the contacts were, by design, too anemic to
handle the 1 Amp+ current they require). He also re-flowed
all dial lamp solder joints, especially at the 'extremes' of the board.
Now dial lamps light solidly and inputs sonically intact.
DC measurements taken
'post-preamp', 'post driver board' and 'post power amp'. Questionable
driver board replaced with another original, inspected component by
component & contacts burnished. Once reseated, DC measurements re-taken.
Once driver board was replaced, then the tech moved to address the
output transistors. Substitute 'generic' outputs and bad original
outputs removed and we 'hand picked' from our extensive collection of
original Sansui 9090 output transistors, and closely matched 'quads' of outputs to re-install. Fresh heat sink
compound used of course.
Green
'LED' Power indicator's 'current limiting' circuit components replaced
as necessary.
The 'typically broken',
Sansui 9090 AM antenna socket replaced
.
We
also aligned the tuner front-end for optimum AM & FM performance as
older internal tuner components have always drifted on vintage gear over
the years. All dial, all meter (including the very difficult to
replace power meter lamps
),
all function indicator and stereo indicator lamps replaced with new
units for years of trouble-free service. Also we 'painstakingly'
replaced the 'dial pointer' lamp. The dial string was cleaned and
re-tensioned. Once unit's electronics were addressed, the unit was
cosmetically detailed inside and out, including rubbing the Real Walnut
Wood veneer case with a fresh coat of lemon oil. All original, extruded
face, and milled aluminum knobs in great shape after detailing. Internal
and external dial screen and window in perfect shape. All inputs tested,
including both phonos, and both amplifiers produces clean and even sine
waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's
dead silent! All functions test fine. The real Walnut wood veneer in
good condition with only very minor wear. Following restoration
procedures, the unit was operated continuously at medium volume, as all
our amplifier / receivers are, into a load with ""Loudness"" on and both
Tone Controls at 10 for 72 hours. On
our test bench, this particular Sansui 990DB, #...0061, amplifiers each
produced XX volts per channel for 1XXwatts per channel @ 8 Ω via
discrete output & XXvolts per channel for
XXwatts per channel @ 4 Ω

VINTAGE STEREO
RECEIVER SANSUI 5000A #...0112 Circa
~1970- ~'72 MIJ
SOLD 2/23/13 SHIPPED TO GEORGIA
Our
technician has completely gone through
and 'Certified'
this unit. Everything was cleaned
inside and out including all contacts, switches and controls. We also
aligned the tuner for optimum AM & FM performance as older internal
tuner components have always drifted on vintage gear over the years. All
meter, dial, function indicator and FM stereo
indicator lamps replaced for trouble-free service (very
difficult to do on this series of receiver and
there's a total of 12). All 4 power transistors removed
and tested for leakage. DC
offset and bias current adjusted to correct levels. Entire unit
cleaned / detailed cosmetically inside and out. All inputs tested and
both side produces clean and even sine waves into static 8 & 4 ohm
loads! No power supply hum of any kind. It's dead silent! All functions
test fine. Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are,
into a load with "Loudness" on and both Tone Controls at 10 for 48
hours
and into a 4 Ohm Load!
While this unit was originally rated at 55 wpc, on our test
bench, both this unit's amplifiers, #...0112 produced peak power of
~XX
volts per channel @ 8 ohms for XX watts and
XX volts @ 4 ohms for
XX
watts per channel via discrete, TO-3, metal cased outputs with 1 kHz
input. (2x Toshiba 2SC1079 & 2x 2SD118).
Idle current measured at 260mA. Bias current & DC offset / output
adjusted to levels within spec. Floor noise measured at
<4mVAC. ____________________________

VERY GOOD TUNER!
AM reception WAY above average, FM reception incredible, PUNCHY and
IMPECCABLY CLEAN!!!
due
to the triple FET FM front end and the quality of the restoration.
ü
All
meter, dial, function indicator and FM stereo indicator lamps replaced
for trouble-free service (very difficult to do on this series of
receiver and there's a total of 12).
ü
All 4
power transistors removed, tested for leakage and reinstalled with fresh
heat-sink compound.
ü
DC offset
checked
(although as it’s a ‘cap couple’ amp, there better not be any DC) and bias current adjusted to correct levels.
ü
Two stuck
dual section controls were replaced and shafts lubed.
ü
Damaged
illuminated dial indicator was replaced.
ü
Entire
unit cleaned / detailed cosmetically inside and out. Only cosmetic
issues with this unit are some scuffing of the wood cabinet and very
minor wear on the face.
ü
All
inputs tested and both sides produce clean and even sine waves into
static 8 & 4 ohm loads! No power supply hum of any kind. It's dead
silent! All functions test fine.

Following
restoration procedures, the unit was run continuously at medium volume,
as all our amplifiers / receivers are, into a load with "Loudness" on
and both Tone Controls at 10 for 48 hours

On our test bench, each internal amplifier of this
particular unit, #...3882, produced peak power of XX
volts @ 8Ω per channel for XX watts / channel
and XX volts @ 4Ω per channel for
XX
watts / channel via Discrete output devices at 1khz. (4X Toshiba metal
case TO-3 2SC1079). AC Idle current at .220A, & floor noise <1.4
mVAC.
____________________________ This is from what many consider to be one of Sansui's best eras. The
Sansui 5000X stereo receiver. The "X" suffix designates upgraded f-6013
driver boards that are sought after by owners of "non-X" units as an
aftermarket upgrade. We have had quite a few
'X000' series Sansui units and they are among some of the best sounding,
'vintage', 'main stream' amplifiers we have heard. Lot's of headroom
and punch! Similar in sound to many of the NAD amplifiers / receivers we
sold back in the 80's. This one also is installed in the optional, REAL
walnut wood veneer case.

for
sale Our technician has
completely gone through this unit cleaning
everything including all switches (actually accessed (requires
'splitting' the unit horizontally) and fully flooded), controls and
contacts for quiet, positive operation.
Extra attention is ALWAYS
necessary on Sansui 8080 / 9090 units to the 'Input Selector'
and 'Dolby / Tape-Monitor' switches, and they were
completely disassembled, thoroughly cleaned, burnished, had contacts
're-sprung' and tested (only about half the 990's, 8080's and 9090's have
input selector switches that will respond to cleaning only). On this
unit, he actually bypassed the wafer portion that routes the dial light
current, and direct wired the lights to be lit constantly
(the
issue with the dial lights on Sansui 880 / 8080-DB / 990 / 9090-DB series
receivers is that the contacts were, by design, too anemic to handle the 1
Amp+ current they require). He also re-flowed all dial lamp solder
joints, especially at the 'extremes' of the board. Now dial lamps light
solidly and inputs sonically intact.
DC measurements taken
'post-preamp', 'post driver board' and 'post power amp'. 'Sansui
2624-Driver-Board 'removed, inspected / tested component by component &
contacts burnished. Once reseated, DC measurements re-taken. Once driver
board was tested, then the tech moved to address the output transistors.
All output transistors removed and individually tested.
Fresh
heat sink compound used of course. Green 'LED' Power
indicator's 'current limiting' circuit components replaced as necessary.
We also aligned the tuner front-end
for optimum AM & FM performance as older internal tuner components have
always drifted on vintage gear over the years. All dial, all meter (including the very difficult to replace power meter lamps
),
all function indicator and stereo indicator lamps replaced with new
units for trouble-free service. Dial light solder
contacts re-flowed. Also we 'painstakingly' replaced the 'dial pointer' lamp.
The dial string was cleaned and re-tensioned. Once unit's electronics
were addressed, the unit was cosmetically detailed inside and out. All original, extruded face, and milled aluminum knobs in
great shape after detailing. Internal and external dial screen and
window in perfect shape. We removed the dial window
and re-finished the black mask behind it. All inputs tested,
including phono input, and
both amplifiers produces clean and even sine waves into static 8 & 4 ohm
loads! No power supply hum of any kind. It's dead silent! All functions
test fine. The Walnut wood grain, vinyl wrapped in good condition with
minor wear. Following restoration procedures, the unit was operated

cased, original TO-3 outputs (Sanken 4x 2SC1116 output
transistors). (AC draw at idle 245mA tested,
DC offset adjusted to <3mV each side.)
The tuner quality on both AM & FM is exceptional due

6/4/12 SHIPPED TO NORTH DAKOTA
Our technician has
completely gone through this unit cleaning
everything including all switches (actually accessed (requires
'splitting' the unit horizontally) and fully flooded), controls and
contacts for quiet, positive operation.
Extra attention is ALWAYS
necessary on Sansui 8080 / 9090 units to the 'Input Selector'
and 'Dolby' switches, and they were completely
disassembled, thoroughly cleaned, burnished, had contacts 're-sprung'
and tested (only about half the 990's, 8080's and 9090's have input
selector switches that will respond to cleaning only). DC measurements taken
'post-preamp', 'post driver board' and 'post power amp'. 'Sansui
2624-Driver-Board 'removed, inspected / tested component by component &
contacts burnished. Once reseated, DC measurements re-taken. Once driver
board was tested, then the tech moved to address the output transistors.
Substitute 'generic' outputs and bad original outputs removed and we
'hand picked' from our extensive collection of original Sansui 9090
output transistors, and matched 'quads' of outputs to re-install. Fresh
heat sink compound used of course. Green 'LED' Power
indicator's 'current limiting' circuit components replaced as necessary.
We also aligned the tuner front-end
for optimum AM & FM performance as older internal tuner components have
always drifted on vintage gear over the years. All dial, all meter (including the very difficult to replace power meter lamps
),
all function indicator and stereo indicator lamps replaced with new
units for years of trouble-free service ('Stereo' indicator replaced
with an LED). Also we 'painstakingly' replaced the 'dial pointer' lamp.
The dial string was cleaned and re-tensioned. Once unit's electronics
were addressed, the unit was cosmetically detailed inside and out,
including rubbing the Real Walnut Wood veneer case with a fresh coat of
lemon oil. All original, extruded face, and milled aluminum knobs in
great shape after detailing. Internal and external dial screen and
window in perfect shape. All inputs tested, including both phonos, and
both amplifiers produces clean and even sine waves into static 8 & 4 ohm
loads! No power supply hum of any kind. It's dead silent! All functions
test fine.
The real Walnut wood veneer in good condition with only very minor wear.
Following restoration procedures, the unit was operated
continuously at medium volume, as all our amplifier / receivers are,
into a load with ""Loudness"" on and both Tone Controls at 10 for 72
hours. On
our test bench, this particular Sansui 9090DB,
#...0129, amplifiers each produced 35 volts
per channel for 153 watts per channel @ 8 Ω via discrete output & 31
volts per channel for 242 watts per channel @ 4 Ω via discrete, Metal
cased, original TO-3 outputs (Toshiba 4x 2SB554 & 4x 2SD424 output
transistors). (AC draw at idle 420mA tested,
DC offset adjusted to <2mV each side.) ___________________________ Here's the first Sansui 9090DB we've had, that's made it all the way
through our restoration with no 'terminal' issues, since 2004! These
receivers are known for great AM/FM tuners, and amplifiers that you can
"darn near weld with".
The tuner quality on both AM & FM is exceptional due
to aspects such as a fully shielded tuning capacitor
. The amps are incredibly warm sounding with HUGE
punch and headroom.
Very "Musical" sounding with real output transistors and huge power
supplies. A testament to the strength of the power supply is that the
results we achieved on the test bench. Most receivers will have from
20-40% more power at 4 Ohms than they do at 8 Ohms. This is primarily
due to power supply limitations. However, the Sansui 9090 at 4 Ohms is
almost double what the receiver's amplifiers are are rated at for 8
Ohms!!! The difference in tone of an 8080 or 9090, with a 'clean bill of
health', and most other receivers is astronomical. It's a difference that must be experienced to be
appreciated.
Again, we done EXTENSIVE
refurbishment / restoration work (~18 hours)
on this unit to insure it's performance. With
the exception of a few very minor 'tic' marks on the front panel, the
face plate, window and knobs
are in great cosmetic condition (see photos above). The 'typically
broken' Sansui 9090 AM antenna socket
still intact and 'un-broken'.

SOLD 12/29/15 SHIPPING TO MAINE
Our
technician has completely gone through
and 'Certified'
this unit, cleaning
everything including all switches, controls and contacts for quiet, positive operation.
Extra
attention is ALWAYS necessary on Sansui units to the 'Input
Selector'
and 'Tape Monitor' switches, and they were thoroughly
cleaned and tested (one great thing about the "G" series, over it's
predecessor series, the 990/9090 and 8080, is that the input selector
contacts are not also conducting the 'dial lamps', so a common
intermittent dial lamp issue with those units is averted on the G-9000). He also re-flowed
all dial lamp solder joints, especially at the 'extremes' of the board.
ALL NEW dial lamps light solidly and inputs sonically intact.
DC measurements
taken 'post-preamp', 'post driver board' and 'post power amp'.
Bias current set to spec.
Green
'LED' Power indicator's 'current limiting' circuit components tested.
We
also aligned the tuner dial indicator and tuner
front-end for optimum AM & FM performance as
older internal tuner components have always drifted on vintage gear over
the years. All dial, all meter (including the very difficult to
replace power meter lamps),
all function indicator and stereo indicator lamps replaced with new
units for years of trouble-free service. Mechanical volume preset disassembled, cleaned and re-lubed.
Once
the unit's electronics were addressed,
it was
cosmetically detailed inside and out. All original, extruded
face, and milled aluminum knobs in great shape after detailing. Internal
and external dial screen and window in perfect shape. All inputs tested,
including both phonos, and both amplifiers produce clean and even sine
waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's
dead silent! All functions test fine.
Only cosmetic issues are minor, ie; a small tic in
the upper, left corner of the face plate, and some minor scuffs on the
sides (see above photos).
The real Walnut wood veneer in
good condition with only very minor wear. Following restoration
procedures, the unit was operated continuously at medium volume, as all
our amplifier / receivers are, into a load with ""Loudness"" on and both
Tone Controls at 10 for 72 hours.
On
