Apologies in advance. This is going to be a long one and I’m going to post on a few other pages. I’m working on an RT-707. The output volume is almost nonexistent out of either channel and from the tape and source. Also the meters don’t move. I think the problem is on the amp board. The diodes (below) are warm though they all test good.The voltages on all of the transistors circled are far off from what they should be. I have removed and tested all of the transistors out of circuit and they are all fine. I’m at my wits end. Does anyone have any suggestions on what I should try next? Thx
