I have a Forte Model 3 on my bench that has bad Bias trimmers, I replaced them with 20 turn pots as everything i have read says the bias is very touchy. this definitely made the bias much easier to precisely adjust BUT, the Owners/Service manual states 70mv across the .47 ohm emitter resistors. but at 45-50mv after 20 minutes the heatsinks are both at 50deg C! I didn't dare push it past that point without getting some clarification.
Any advice?
