I have good and bad news friends. The good news is the amplifier works with a temporary clip lead jumper in place of the open control wire between the input and output relays. Seems to have no issues

By the way, these opens were not in the plugs. The problem was in the wires. I reused the plugs in both cases, splicing the new wire into the old wire coming out of the plugs about 1 to 1.5 inches be

Frank, the amp should go to operate mode after the warm up delay if you push the mode switch to operate. It should go to operate mode regardless if the amp is keyed or not. It wont go to operate mode

The two amps I repaired did not have Alphamax, so the software may be able to put it into operate mode without the mode switch being in operate. I dont know. No experience with Alphamax. 73 Charlie N
