Did you know?
A SUPER LOW DISTORTION RATING COULD LIKELY BE A BAD THING!...
THD
(Total Harmonic Distortion) – THD is a measure of the how much a given audio device may distort a signal through the inevitable introduction of added harmonics or overtones. These figures are usually given as percentages. THD figures below approximately 1% are inaudible to most people (although market promotion efficiencies have 'brain-washed' much of the 'audio-public' into weighting low THD with almost 'holy grail' importance. I remember some manufacturers touting numbers as low as <0.003% in the early Eighties).  Low THD is not always an indication of a high quality amplifier. In fact, it is / was more commonly just the opposite. Some of the 'highest end' (read REALLY expensive) and certainly best sounding units will have distortions somewhere between .1% & 1%.
Low THD is only a simple 'bi-product' of 2 aspects. The first was an inordinate and increasing amount of 'global / negative feedback' built into amplifiers primarily to suppress distortion. This practice started to occur in the late 1970's and certainly was in 'full force' past the early 1980's for most 'main stream' consumer-grade audio amplifiers. Unfortunately this also 'suppressed' tone and 'punch' (musicality) but it made the numbers look good to the 'spoon fed' consumer (kind of like overly high speaker wattage numbers, and sorry if you're in that group and, most folks were so you're not alone). Secondly manufacturers were moving away from 'discrete-transistor' output designs to more 'monolithic' 'power-pack' output designs. While these designs reduced power supply requirements, thus reducing parts costs and weight (also translates to lower prices due to savings on freight from Asia) they generally sounded anywhere from somewhat 'anemic' compared with the designs from a few years previous, to completely 'gutless' and 'un-musical'. But, hey,… they had very low distortion figures….Can anyone say 'threw the baby out with the bath water'?

So, why do the older / 'vintage' receivers and amplifiers sound so much better (for music) than the much more modern and fancier, 'surround sound - 5.1', '7.1', or '8.BR549' A/V receivers?

 Mostly due to Amplifier design and 'Amplification Classes' - All sound is a sinusoidal waveform. It has alternating peaks and valleys. The center point of each wave is the zero, or switching point that separates the positive (top) from the negative (bottom) portion of each wave. When a amplifier operates in 'Class A' , the output tubes or transistors amplify the entire waveform without splitting it into positive and negative halves. In 'Class AB', (used in the majority of classic receiver / amplifier designs), the signal is split into two halves, positive and negative, and each half is sent to a tube or transistor circuit for amplification. Both sides work in tandem, and the two halves are recombined at the output section to reconstruct the whole signal. This technique increases the amount of power that can be applied, but increases distortion.
In many 'modern' A/V and subwoofer amps, 'Class-D' is the dominant design method. Class D operation is essentially a rapidly switching power amplifier. Here the output devices are rapidly switched on and off at least twice for each cycle. Theoretically, since the output devices are either completely on or completely off they do not dissipate any power (heat), greatly increasing efficiency and lowering manufacturing cost thru lesser parts and lighter freight weight. Not musically the best sounding design for listening to standard, 2-channel music (Radio, Vinyl, CD'S, DAT, Tape (not 'crappy' compressed, MP3 formatted files), but popular for 'A/V-Surround-Sound' systems for reproducing 'movie sound tracks' (not too difficult to do from a 'sonic quality standpoint') where slightly elevated levels of distortion are tolerated and for subwoofer use where maximum power is necessary, and slightly elevated levels of distortion are also easily tolerated.

Did you know?
What is the difference between a ‘Tuner’ and a ‘Receiver'?

A ‘Tuner’ is the component or aspect of an audio system that receives or ‘Tunes-In’ Radio Stations.
A 2-channel, stereo ‘Receiver’ is really 3 units in one!
It’s a ‘Tuner’ for receiving radio stations. It’s a ‘Pre-Amp / Control-Amp’ for source / input selection & tone / audio signal modification (with likely the phono 'pre-amp / head-amp' built-in). Lastly it’s a ‘Power Amplifier’ to energize your speakers. It's essentially the 'heart' of most audio / stereo systems.
Some manufacturers would silk-screen 'Tuner-Amplifier' on the front of their receivers, but that was / is simply 'marketing' to make it sound as if it's something more complicated. It's still a 'receiver'. Just FYI.

 

 

 

What is a 'Receiver' and how is it different than a 'Tuner' or an 'Amp'?
The term 'Receiver' refers to a combined unit consisting of at least 3 aspects incorporated into one. The 3 basic units are the AM/FM 'Tuner' or radio, a 'Pre-Amplifier' / 'Control-Amp' and a 'Power-Amplifier' all combined in one 'box'. Originally the general consensus was that 'receivers' did not perform as well as 'separates' and were sonically inferior. While this may have been the case early on, as in the

 

late 1950's to early '60's, technology improved quickly and by the mid-late 60's the arguments for separates over receivers for most 'mid-level' consumer Hi-Fi applications were generally without merit. For 95% of home-audio listeners, a receiver will be more than ample.

Again, as stated before, we have completely gone through this Sanyo 2033, Stereo Receiver cleaning and testing all and it gets our full 'Certification' . All functions test fine. 
Again, this unit does have a few minor 'battle wounds', but nothing too detracting and it makes up for it in performance. Sanyo, was a manufacturer for many brands, and tended to use fairly superior parts on their 'branded' units, even though they were not 'highly' marketed. I sold Sanyo for years when new, and their failure rate was among the lowest. This unit is no exception as it is also utilizing very great 'feeling', quality switches, pots and parts. Wood grained vinyl covered case in great shape. This receiver decent, works, and sounds great!
Unit measures 17.25" wide x 6" tall x 13" deep and weighs 18 lbs unpacked. Includes our standard 90 day limited warranty.

SOLD 2/3/14
SHIPPING TO CALIFORNIA

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. Tuner string re-tightened and aligned. 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). Defective 'Low Filter' switch replaced with original. All 4 power transistors removed, tested for leakage and re-installed with fresh heat-sink compound. Driver board changed, then Electrolytic caps on driver boards inspected and changed where necessary. DC offset and bias PC mounted pots cleaned and 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 ~20.5 volts per channel @ 8 ohms for 52 watts and 17 volts @ 4 ohms for 72 watts per channel via discrete, TO-3, metal cased outputs with 1 kHz input. (4x Toshiba 2SC1118). Idle current measured at 250mA. Bias current & DC offset / output adjusted to levels within spec. Floor noise measured at <0.6mVAC.

Did you know?
Sansui was founded in 1947, just after WWII as a company manufacturing transformers (one of the most important components of any audio system). During the Sixties they morphed into what would become one of the most well respected companies in quality audio gear. I have owned and sold some incredible Sansui stereo gear from the Seventies and early Eighties. I worked at a Sansui dealer in the early part of the Eighties. Sansui remained a major force in stereo gear until about the mid Eighties, when the vast majority of audio gear started suffering from the 'how cheaply can we get it' syndrome by consumers, thus manufacturers followed suit, by building cheaper and cheaper gear.

ü  Our technician has completely gone through and 'Certified' this unit.

ü  Everything was cleaned inside and out including all contacts, switches and controls.

ü  Multiple (ALL), 'typically-sticky' push switches removed, overhauled / cleaned and lubed across front

ü  Dial glass removed and completely / solidly re-attached

ü  Skewed control shafts straightened

ü  Electrolytic power supply filter capacitors tested for leakage

ü  Balance of Electrolytic capacitors inspected and replaced as necessary

ü  All question-able and common 'stress point' solder joints re-flowed

ü  All 4 power transistors removed, tested for leakage

ü  Shorted / bad output transistors replaced with ‘new’ 2SC1079 TO-3’s

ü  All output transistors re-installed with fresh heat-sink compound (usually good for 20-30 years)

ü  Bias current adjusted to correct levels.

ü  DC offset adjusted to super low levels.

ü  We also aligned the tuner for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years. VERY GOOD TUNER! AM reception WAY above average, FM reception incredible, PUNCHY, with GREAT SEPARATION and IMPECCABLY CLEAN!!! due to the 'Pair of Dual-Gate MOS-FETS' FM front end and the quality of the restoration.

ü  All (18 in total) meter, dial, function indicator, 'Speaker Indicator' (not an easy task) and FM stereo indicator lamps replaced for trouble-free service (dial / meter lamps ‘blue tinted’ to original color)

ü  Entire unit cleaned / detailed cosmetically inside and out. Only cosmetic issue is that some 'id' info has been 'rubbed / ground' off the top edge of the face plate at sometime in the past (not seen from the front of the unit, only when looking down on it)

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.

ü  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 and into a 4 Ohm Load!

You will not be disappointed. Total restoration time investment ~8 hours.  

On our test bench, the internal amplifiers of this receiver #...777M produced 23 volts per channel @ 8 ohms with 1Khz input for 66 watts and 18 volts per channel @ 4 ohms with 1Khz input for 81 watts via discrete, TO-3, metal cased outputs. (2x 2SA679 & 2x 2SC1079).
 AC Idle current at 400mA, Bias adjusted and DC offset output adjusted to < 0.6 mV DC either channel Floor noise @ <0.5mV AC either channel.

Most techs, including myself, who have been inside of the various SX Pioneer series receivers, can see quite a few examples of why they believe earlier series are better built than the later series, especially once 1980-81 rolled around. Things TO-3, metal cased outputs, shielding around the control pots and some sensitive circuit boards to reduce RFI noise, heavier control pots and Molex connected pre-driver / output circuit boards to facilitate future service.
Again, we have completely gone through this Pioneer SX-838 Stereo Receiver, as stated above and '
certified' it's ready to go!
This is the first SX-838 (or any of that series) we've had in quite a few years. Cosmetically, with the exception of the previously mentioned 'id' info, the unit is in overall, great condition. Unit looks good, works great and sounds HUGE! Includes an 'e' copy of the original Pioneer SX-939 (essentially the same as the SX-838, just a bit more power) owners / users / instruction manual, and brochure. Measures 20.5" wide x 16.5" deep x 6.75" high and weighs a HEAVY 35 lbs unpacked. Includes our standard 90 day limited warranty!

Did you know?
While the company 'Pioneer' was officially established in 1961, the founder was actually developing speakers as early as 1937. In 1962 Pioneer marketed the worlds first 'separate component' stereo system for the home, and in 1975, the worlds first 'component system' for the car. In 1984 they introduced the first CD player for the automotive use (and I was selling it then). Pioneer had many other 'firsts' and continue to be a major 'player' in consumer, professional and industrial electronics.

-
 
Everything was cleaned inside and out including all contacts, switches, controls and I/O jacks.  
-
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. Tuner digital readout is within 0.1Mhz of spec, meaning example '98.1' reads '98.2'.  
-
Battery backup compartment clean and corrosion free.  
-
Generally AM reception in a stereo receiver is treated as an 'after thought', but the AM reception on this Vector Research VRX-9000, #...4176 is WAY above average (frankly it's amazing). VERY GOOD TUNER! FM reception as well great and IMPECCABLY CLEAN!!!  
-
Power indicator meter lamps replaced.  
-
