Pioneer SX-950 Amp Board Rebuild Kit AWH-050 Recap & Repair Kit Complete!
Up for sale here is this AWH-050 amplifier board rebuild set for a Pioneer SX-950. This is all the parts you need to rebuild a Pioneer SX-950 amplifier board. Over time the amp boards start developing issues with transistors and capacitors, and sometimes completely blow up. The old parts are weak and failing. We will make them new again! This kit includes all 8 capacitors, all 12 transistors, and all 4 trimmers. It does NOT include the big white resistors, any other resistors, or any output transistors. I have new OnSemi MJ21195G/MJ21196G outputs listed here if you need them, and I have the big white emitter resistors available here. The entire amp board uses 8 outputs (4 pairs), and you should replace all 4 on the channel if you are replacing any. Please don't buy any of the Chinese output transistors on eBay--those are counterfeit and will blow up. These are extremely high-quality parts, the same ones I use when I rebuild Pioneer gear. The capacitors are Nichicon PW, Nichicon KT, and Wima film caps at the correct uf and the same or higher voltage ratings, the trimmers are new Bourns trimmers, and the transistors are Fairchild/Onsemi and are the correct subs for the original transistors. Frankly, "recapping" is a waste of time if you're not going to replace the transistors as well. A lot of times the transistors age worse than the caps, so you should definitely change out the transistors while you're in there. If you're having amp board issues, it's very likely to be a transistor issue. If your amplifier board has actually "blown up" and you see smoke marks and blackened components, those are most likely resistors and will need to be replaced as well. I will include a surprisingly well-written instruction sheet, but this is a pretty complicated repair, so if you don't have much experience with this, buy the kit and take it to a professional. You should definitely have a fair amount of soldering experience and have a decent soldering iron, a dim-bulb tester, and heat-sink compound, as well as the usual tools. Please see my pictures for details. US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask. Looking for more parts? I have power switches, feet, pushbuttons, top case screws, bottom screws, faceplate screws, white LED fuse lamps, blue LED fuse lamps, 6.3v bi-pin bulbs, 8v bi-pin bulbs, 12v bi-pin bulbs, wired 8v 60ma bulbs, new main capacitors for the Marantz 1060/2230, wired Pioneer speaker plug replacements, and more. Just use "add to cart" on everything you want and then check out for combined shipping.
