I have rebuilt 3 of these and am having trouble with the 4th, I am using the same substitutes as with the others but this one has stumped me. It is the AW115-1071 board power amp board, I am getting over -57 volts on the terminal 19 output which is turning off the protection circuit. I have checked all of the components and verified the pin outs of the replacement transistors. I'm not sure where to go from here. Any help would be greatly appreciated.
