Up for sale here is this complete rebuild kit for the Kenwood KA-7100.  This includes all the parts you need to rebuild all the boards in the Kenwood KA-7100, and it includes new replacement main filter capacitors as well.  Some KA-7100s have heat-sinks on the Q31/Q32 transistors and some do not have them.  Those two resistors need to be heat-sinked, so the kit includes two heat-sinks with mounting hardware in order to properly mount the transistors.

This kit includes:

Power Supply:
10 capacitors (including 4 main filter caps)
2 transistors
11 diodes (2 zener)
2 heat-sinks with hardware
1 relay

Amp Board:
11 capacitors
6 transistors

Preamp Board:
9 capacitors
4 transistors

Control Board:
18 capacitors
8 transistors

These are all high-quality brand new genuine parts, the same ones I use when I rebuild vintage gear.  The capacitors are 105° Panasonic FC, Nichicon PW, Nichicon KL, Nichicon Muse, Wima film, and Nichicon VR (for the main caps) at the correct uf and the same or improved voltage ratings, the transistors are Fairchild/OnSemi, and the relay is a new Omron relay.

I will include surprisingly well-written instruction sheets, but this is a fairly complicated rebuild, and you should know what you're doing and have a decent soldering iron, a little heat-sink compound, and a dim-bulb tester with a 100W incandescent bulb.  Please see my pictures for details.

US shipping and handling is $10, and international is $28.  If you have any questions, please ask.
