Very nice job! How did the unit work after the effort and time? I asked around about WOPL for my PL700/1 that is stuck in protection circuit mode, and the replies I received were overwhelming for the "don't waste your time & money/not worth doing" side of the opinion poll! Ican understand the OG 700/1 is kind of a red-ish tinted dred lock lookin' step child, but I had that amp for many years & it was reliable and was 50 years old when it finally quit working... Lots of HiFi amps stop working long before that age!! I don't have the training,skill, or any of the necessary test equipmet needed to fix the unit. But I have not given up on finding a way to put it back in service playing music for someone else to enjoy. I enjoyed reading your comments that were posted as you put that board together. THANK YOU!!
