Up for sale here is this rebuild kit for the Pioneer SA-6800, aka the SA-608. This includes all the parts you need to rebuild the Pioneer SA-6800/SA-608 AF Assembly board, EQ board, and indicator board.

This kit includes the following:

AF Assembly Board:
25 capacitors (Nichicon PW, Nichicon Muse, Wima film, Nichicon VY for the main caps)
3 transistors
1 relay (Omron)

EQ Assembly Board:
8 capacitors (Nichicon PW, Wima film)

Indicator Board: 
4 capacitors (Nichicon PW, Wima film)

Instructions

The kit for each board is bagged individually to make things easier.

These are all high-quality brand new genuine parts. The main capacitors are Nichicon VY 10000 uf 50v capacitors, the other capacitors are 105° Nichicon PW, Nichicon Muse, 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 rebuilding an amplifier is moderately complicated, and you should know what you're doing and have a decent soldering iron, heat-sink compound, and a dim-bulb tester with a 40W, 60W, or 100W incandescent bulb. Please see my pictures for details.

US shipping and handling is $6, and international is $28. If you have any questions, please ask.
