Up for sale here is this amplifier board rebuild set for the Pioneer SX-737. This includes all the parts you need to rebuild a Pioneer SX-737 AWH-033 amplifier board. The old parts are weak and failing. We will make them new again! Some SX-737s will have an aggressive crackle in one or both channels from aging transistors, and this kit will usually fix that.

This kit includes all 8 capacitors, all 10 transistors, and 4 replacement trimmers for the amplifier board. This does NOT include any output transistors.  The correct new output transistors for the SX-737 are two MJ21195G (replaces 2SB541) and two MJ21196G (replaces 2SD388), which are available here.

These are all high-quality brand new genuine parts. The capacitors are 105° Nichicon PW caps and Wima film caps, and the transistors are new OnSemi and Toshiba transistors, the correct subs for the original transistors.  These are extremely high-quality parts, the same ones I use when I rebuild Pioneer equipment.  Please note that some SX-737s incorrectly have 4.7 uf caps on the amp board.  These are replaced with .33 uf caps, which are the correct value.

I will include surprisingly well-written instructions, but this is moderately complicated, and you should know what you're doing and have a decent soldering iron and a dim-bulb tester with a 40W, 60W, or 100W incandescent bulb.  This kit is designed to either update a working amp board or repair a non-working one.  If any of your resistors are blown/burnt you will need to get those.  I have replacement 0.5 ohm 5W emitter resistors here.

US shipping and handling is $6, and international is $20, 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.
