Item Tag: SX-737

Up for sale here is this rebuild kit for a Pioneer SX-737. This is all the parts you need to completely rebuild a Pioneer SX-737. It includes parts for the power supply board, protection board, amplifier board, preamp board, mic board, tuner board, and phono EQ board, and includes a new relay with standoffs and upgraded replacement main capacitors. This does not have new lights, fuses, or output transistors. This includes the following:11 capacitors, 9 diodes, and 4 transistors for the power supply board6 capacitors, 7 transistors, and 9 diodes for the protection board (one diode for the diode mod)16 capacitors and 6 transistors for the preamp board (one cap for the other preamp board)8 capacitors and 6 transistors for the phono EQ board10 capacitors,10 transistors, and 4 trimmers for the amplifier board (includes replacements for drivers)4 capacitors and 2 transistors for the mic board15 capacitors and 2 transistors for the tuner board (only the 2SA725 transistors are replaced)1 new Omron relay (top flange instead of old bottom flange design, includes standoffs for mounting plus instructions on how to mount new relay inside old relay cover)2 new main caps (10000 uf 80v, the same diameter as the old caps)Instruction sheet These are all high-quality brand new genuine parts. The main caps are Nippon Chemi-Con 10000 uf 80v caps, the other capacitors are Panasonic FC, Nichicon PW, Nichicon KL, and Wima film caps at the same uf ratings and the same or higher voltage ratings, the diodes are all the correct replacements, the relay is a new Omron relay, and the transistors are new Fairchild/OnSemi KSC1845, KSA992, KSC2383, KSC2073, KSC2690, and KSA1220 transistors, the correct subs for the original transistors. 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. Please see my pictures for details. US shipping and handling is $10, 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!
