Up for sale here is this power supply recap set for a Pioneer SX-780. This is all the parts you need to rebuild a Pioneer SX-780 power supply section, found at the left side of the large circuit board. Over time, the three power supply heat-sinked transistors in the SX-780 run so hot that they often desolder themselves or overheat and die, leading to a receiver that won’t come out of protection. The old parts are weak and failing. We will make them new again! This kit includes all 6 capacitors, 4 transistors, 8 diodes, and a replacement relay. These are all high-quality brand new genuine parts. The capacitors are 105° Panasonic FC and Nichicon PW caps at the correct uf and the same or higher voltage ratings, the transistors are the correct OnSemi subs for the original transistors, the diodes are 1N4004s and 1N5404 diodes, and the relay is a new Omron relay. These are extremely high-quality parts, and they are what I use when I rebuild Pioneer gear. This kit is not guaranteed to fix your SX-780 if it will not come out of protection, but it will certainly help it run better, and will fix many non-working SX-780s. This kit does not include the two large main filter capacitors. I will include surprisingly well-written instructions, but this is mildly complicated, and you should know what you’re doing and have a decent soldering iron, as well as a little heat-sink compound. 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.
