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.

SOLD 7/30/12
SHIPPED TO CALIFORNIA

We have completely gone through this cleaning inside and out including all contacts, switches and controls. All dial / meter lamps replaced with new bulbs, as well as the 'Stereo' indicator, for trouble-free service. We also aligned the tuner for optimum performance on both AM and FM including adjusting 'sensitivity', 'MPX' circuit and 'FM Stereo Separation'. All functions tested for perfect operation. Cosmetically with the exception of a minor finish chip on the left, rear corner of the case, and a minor 'smug' in the chrome trim around the tuner dial, the unit looks near new. Following electronic refurb work, entire unit was detailed inside and out.

Both amplifiers on this particular Pioneer SX-535 Stereo Receiver, #...865S had output that was measured at 13.75 volts per channel @ 8 Ohms for XX watts and 11.25 volts per channel at 4 Ohms for XX wpc, via discrete epoxy outputs (2x 2SA489 & 2x 2SC789 output transistors).

HEY, WHY ALL THE 'X'd' OUT / OMITTED SPECS AND TEXT?


AC current at idle measured at 0.2A. DC offset measured at <.23mV on either channel output.

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out
including all contacts, switches and controls. AM & FM tuner re-aligned and front-end adjusted for optimum performance. All dial and tuning meter lamps were replaced as well as the power back light bulb. Amplifier section had output bias and DC offset adjusted to spec levels. 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!  
  

   
On our test bench, the internal amplifiers of this particular unit Pioneer SX-720 stereo receiver, #...1190S, produced a strong XX volts per channel @ 8 ohms for XX watts and 1XX volts @ 4 ohms for XX watts per channel via discrete outputs with 1 kHz input. (2x  NEC D883A & 2X NEC B773A output transistors.)

Our technician has completely gone through and 'Certified' this unit.
- This receiver has had complete service including all switches, contacts, and controls cleaned for static free performance.
- Entire unit completely cleaned inside and out. 

- All dial, meter, indicator, 'Power', 'FM' and 'Stereo' lamps replaced with new unit for trouble-free service.  
- Dial lamps aqua tinted for factory new appearance.  All other indicator lamps replaced.
- Power cord replaced with polarized plug for quiet operation.

- Power transformer secondary's checked for correct output voltage

- Power Supply, Rectifier and Protection circuits all reflowed for improved reliability. ('original' capacitors on the power supply / rectifier board are common issue on the SX-750 for some reason. We don't see it so much on other models. No issues once corrected with fresh caps)

- Power Supply filter electrolytic capacitors replaced with new, audio grade caps, as well as protection and regulator capacitors.

- We also aligned the tuner front-end for optimum performance as older tuner components have drifted over the years.
VERY GOOD TUNER! FM reception incredible and IMPECCABLY CLEAN!!!
-
All inputs and outputs tested and both sides produce clean and even sine waves into static 8 & 4 ohm loads at full power! No power supply hum of any kind. It's dead silent! All functions test fine.
Wood grained vinyl case also in decent shape with a few 'battle scars', but nothing too distracting (see photos).
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! All functions test perfectly.

 
 The Pioneer SX-750 was originally rated for XX watts, but both internal power amplifiers on this unit, #...119S  produced XX volts at 8 ohms per channel for XX watts / channel and XX volts at 4 ohms per

Our technician has completely gone through and 'Certified' this unit. Receiver has had complete service including all switches, contacts, and controls cleaned for static free performance, complete cleaning inside and out. Solder joints on controls 're-flowed'. All dial & meter lamps replaced with new units for trouble-free service (and 'aqua' coated prior to installing). All other indicator lamps checked. Cosmetically, it's 'LIKE NEW'! We also aligned the tuner front-end for optimum performance as older tuner components have drifted over the years. VERY GOOD TUNER! AM reception WAY above average, FM reception incredible, PUNCHY and IMPECCABLY CLEAN!!! All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm, 'brick wall' 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. All functions test perfectly. This one is also cosmetically "Like New" in every respect! No issues anywhere.

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

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

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

  Dial glass removed and completely / solidly re-attached

  Skewed control shafts straightened

  Electrolytic power supply filter capacitors tested for leakage

  Balance of Electrolytic capacitors inspected and replaced as necessary

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

  All 4 power transistors removed, tested for leakage

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

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

  Bias current adjusted to correct levels.

  DC offset adjusted to super low levels.

  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 ...

HEY, WHY ALL THE 'X'd' OUT / OMITTED SPECS AND TEXT?

  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)

  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)

  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 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 xx volts per channel @ 8 ohms with 1Khz input for xx watts and xx volts per channel @ 4 ohms with 1Khz input for xx watts via discrete, TO-3, metal cased outputs. (2x 2SA679 & 2x 2SC1079).

SHIPPED TO GEORGIA

  We have completely gone through this unit cleaning everything including all switches, controls and contacts
(requires the complete disassembly of the front 'two layers' of the receiver) and removal of the circuit boards to access). We corrected some previous 'shoddy' repair work that had been done in the past on this one, including correcting the dial string motion, as it had been 'reversed'. We also replaced the entire flywheel mechanism as the original had lubrication that was 'gelling', and caused it to be 'stiff' to turn. We re-built a section of the power supply, replacing a bad zener diode and an entirely missing 2SD325R 'voltage regulator' and heat sink. Also, there was no 'heat sink compound' on any of the voltage regulators, from the factor, so we removed all six of them, and applied fresh heat sink compound. We also, removed all the output transistors, and applied fresh heat sink compound to them for the absolute best heat transfer for cooling. We then aligned the tuner front-end for optimum performance as older tuner components have drifted over the years. All internal control pots and switches are super quality ALPS brand. The best brand Pioneer could have picked. All dial lamps replaced with new lamps for trouble-free service. Following this, the entire unit was cosmetically detailed. All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads!
  
  On our test bench, this unit's amplifiers produced xxx volts per channel at 8 ohms for xx watts per channel and xxx volts per channel at 4 ohms for xxx watts each channel via Discrete outputs. (The SX-x80 series

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out

Replaced AC convenience outlets with better condition units. Re-tensioned tuner string and re-centered pointer to correct dial position. VERY GOOD FM TUNER!

We replaced ALL dial, meter (with 'blue dyed' bulbs) and the dial pointer lamps with new units for trouble-free service. All inputs tested and both sides produce clean and even sine waves into 'brick-wall' 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine.

HEY, WHY ALL THE 'X'd' OUT / OMITTED SPECS AND TEXT?

This model ALONE also features two HUGE and separate, vertically finned heat-sinks, that are EXTERNALLY located for max passive cooling (all heat sinks on larger amps should be located 'externally', but alas, many aren't. That means the much of the 'electronics destroying heat' is trapped within the cabinet, and doesn't escape easily. On a side note, replacement Pioneer SX-1250 heat-sinks are one of the most requested parts we get calls for. This is due to 'in-experienced sellers' / 'packers' typically selling on the 'on-line auctions', inadequately & inappropriately packing SX-1250's for shipment. The SX-1250 is a 64 POUND BRUT, with the rear corners being made of the heat sinks (all corners and controls are vulnerable by the way). They MUST be packed by someone, YES, LIKE US, who knows what they're doing!!!)
