In troubleshooting my Kenwood KR6200 receiver, I had to use some schematics. I also had to make minor corrections and notes along the way. I'll post them here for others to benefit. Click on an image to see it full size.

Some of the following links are just text files. If they don't open in Notepad (or Wordpad etc.), just select all of the text and copy it. Then open Notepad (or Wordpad etc.) and paste it. Then turn on the "word wrap" option if needed.

These are corrections to the service manual and my notes on the problems I've had on my receiver.
