Up for sale here is this rebuild kit for the Pioneer SX-950. This includes all the parts you need to rebuild a Pioneer SX-950, and includes upgraded replacement main capacitors. This does not include new lights, fuses, or any resistors (except for the bleeder resistors for the main caps). This also does not include the driver or output transistors. Correct replacement outputs are MJ21195G/MJ21196G, available here. Please don’t buy any of the fake Chinese transistors on eBay–those are counterfeit and will blow up. This kit includes replacements for all the electrolytic capacitors in the receiver, including the two main filter capacitors, which are upgraded to 22000 uf 80v Cornell-Dubilier caps. The new caps are the same diameter as the old ones so they will fit the old clamps perfectly. The kit also includes replacements for almost all the transistors on all the boards except the tuner board. Transistors frequently age worse than the capacitors, so you have to replace them when you’re doing a rebuild. The kit for the power supply includes replacement diodes and zener diodes, which are important to replace, and the protection board kit includes a new Omron relay with standoffs. You will also receive detailed instructions to help this go more easily. These are all high-quality brand new genuine parts, the same ones I use when I rebuild Pioneer equipment. Capacitors are Nichicon PW, Nichicon KL, Panasonic FC, Wima film, and Cornell-Dubilier for the main filters. Transistors are Fairchild/Onsemi. Trimmers (for the amp board) are Bourns. I will include a surprisingly well-written instruction sheet, but rebuilding a receiver is fairly complicated, and you should know what you’re doing and have a decent soldering iron, heat-sink compound, and a dim-bulb tester. I have rebuilt a lot of SX-950s in the past few years–they’re really nice receivers, and aren’t too bad to work on. Please see my pictures for details. US shipping and handling is $12, and international is $28. If you have any questions, please ask. I have other kits and lots of vintage electronics listed–feel free to take a look!

Up for sale here is this rebuild kit for a Pioneer SX-838. This includes all the parts you need to rebuild the Pioneer SX-838 power supply board, protection board, amplifier board, phono EQ board, mic board, tuner board, and preamp board, plus it includes upgraded replacement main capacitors and a new relay. This does not include lights, fuses, or output transistors. The correct replacement output transistors are two MJ21195G (replaces 2SA679) and two MJ21196G (replaces 2SC1079), available here. Please do not buy any of the Chinese output transistors listed on eBay–these are counterfeit and will damage your receiver.

These are all high-quality brand new genuine parts. The main capacitors are Cornell-Dubilier 12000 uf 80v capacitors and one 1500 uf 100v Epcos cap, the other capacitors are 105° Panasonic FC, Nichicon VY, Nichicon PW, Nichicon KL, and Wima film caps at the same uf ratings and the same or higher voltage ratings, the transistors and diodes are the correct Fairchild/Onsemi subs for the original transistors, the relay is a new Omron relay, and the trimmers are new Bourns trimmers. These are extremely high-quality parts, the same ones I use when I rebuild Pioneer equipment. I will include surprisingly well-written instructions, but rebuilding a receiver is moderately complicated, and you should know what you’re doing and have a decent soldering iron, heat-sink compound, and a dim-bulb tester with a 60W or 100W incandescent bulb. Please see my pictures for details. US shipping and handling is $12, and international is $28. If you have any questions, please ask. Looking for more parts?

These are extremely high-quality parts, and they are what I use when I rebuild Pioneer equipment. I just finished an SX-737 rebuild, which is why I put this kit together. This kit is the exact same stuff I use. The Wima film caps cost more than electrolytics, but they sound better and are definitely worth it. I will include surprisingly well-written instructions, but rebuilding a receiver is moderately complicated, and you should know what you’re doing and have a decent soldering iron and a dim-bulb tester, as well as a little heat-sink compound.

Up for sale here is this rebuild kit for a Pioneer SX-450. This includes all the parts you need to rebuild a Pioneer SX-450, and includes upgraded replacement main capacitors and output transistors. This does not include new lights, fuses, or any resistors, though I have the lights listed separately. This includes the following:7 diodes (including four 1N5404 for the main rectifier bridge)50 capacitors (including new main caps)27 transistors (replacements for outputs, drivers, all other transistors except a few in the tuner)Instructions These are all high-quality brand new genuine parts. The main caps are Cornell-Dubilier 4700 uf 63v caps, and the other capacitors are 105° Panasonic FC, Nichicon PW, Nichicon KL, and Wima film caps at the same uf ratings and the same or higher voltage ratings. The transistors are new OnSemi TIP41C, KSC2383YTA, KSC2690, KSC1845FTA, KSA992FTA, and KSA1013 transistors, which are the correct subs for the original transistors. These are extremely high-quality parts, the same ones I use when I rebuild Pioneer equipment. I will include surprisingly well-written instructions, but this is fairly complicated, and you should know what you’re doing and have a decent soldering iron and a dim-bulb tester, as well as a little heat-sink compound. The number-one issue with the Pioneer SX-450, SX-550, SX-650, and SX-750 is bad power switch contacts. If your receiver lights flicker when you turn it on and you hear a sort of fizzing sound from the front left, it’s probably bad power switch contacts. This is a challenging fix but the instructions go over how to do this, step-by-step. Please see my pictures for details. US shipping and handling is $6, and international is $28.
