Picked up a randall rg100es from local pawn shop. someone had removed all 4 output tansistors. I bought replacements my issue is the board isnt labled at all for components. I installed the transistors and done what testing i could before i powered it up. Voltages seem ok from what i can make from the schematic. Im not getting any volume out the speaker outputs. I can hear it faintly and shows a weak signal on scope. It works through the signal out jack into another amp. One question i have is were the original power transistors 2n6254 insulated between the transistor and heatsink? Any help with getting this amp going would be greatly appreciated.
