ChrisM	Re: bias pot location on JCM 800 Marshalls I had the Silver Jubille Marshall, and it's from about the same era as your amp. It had one small plastic pot about in the middle of the circuit board. Shouldn't be too hard to find. Like John said, it's the only pot on the board(as far as I can remember).     -Chris
