[QUOTE="nsbluesman, post: 76065, member: 2612"] Hi All: I have a RG50TC opened up on my bench right now and it is puzzling me, all tubes have been testted and swapped out for known good ones, heater voltages check out, VDC on tubes 1, 2 VAC on 3,4,5,6. Plate voltages appear normal for a 6L6 AB amp. The gain channel has volume, not sure if I would say normal, but definitely way louder than the clean channel. with the volume all the way up on the clean channel it's really really quiet. I have a copy of the schematic, but there aren't too many voltage refs listed, complicated little sucker and I would love to be able to try it out at full power. Any thoughts or suggestions of where to start looking, I did see some posts about the bridge rectifier in the heater circuit for valves 1 and 2, but the voltages look good.. Puzzled in Nova Scotia..
