Up for sale here is this rebuild kit for the Pioneer SG-9500 equalizer.  This includes all the parts you need to rebuild the Pioneer SG-9500 power supply board and both equalizer boards.

This kit includes the following:

Power Supply Board:
9 capacitors (Nichicon PW, Wima film)

Equalizer Boards:
20 capacitors (Nichicon PW, Nichicon KL, Panasonic FC)
6 transistors (Onsemi)

Instructions

The kits for the power supply and for the equalizers are bagged separately to make things easier.

These are all high-quality brand new genuine parts. The capacitors are 105° Nichicon PW, Nichicon KL, Panasonic FC, and Wima film caps at the same uf ratings and the same or higher voltage ratings, and the transistors are the correct Onsemi 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 a little complicated, and you should know what you're doing and have a decent soldering iron. Please see my pictures for details.

US shipping and handling is $5, and international is $18. If you have any questions, please ask.
