GK 800RB Schematics for initial plus 2 redesigns
9 Attachment(s)
I have been dealing with some noise with my 800rb and so I have done some research. I found some schematics on this site, but I also found a service memo that got me a bit confused as the pots didn't seem to match what was inside my amp.

So, after a bit more looking I found that there have been a few redesigns for this amp. I have attached schematics from 1982, 1991 and 1992. I haven't looked at the differences between 91 and 92, but 82 is notable as it uses a single pot for the hi/low crossover whereas the 91 and 92 use 2 pots ganged together.

Hope this helps someone. It sure helped me.
