I was able to fix the meter yesterday. Last night I tried the alignment procedure with my multimeter, which doesn't measure RMS. Before I purchase a new multimeter that measured RMS, I wanted to see if there was a way to measure the same voltage on either side to set the left meter exactly the same as my right meter. Adjusting the trimmer pots at RX03 and RX07 didn't yield any results again, so I thought I would try blowing air and some deoxit at the pivot just in case some dirt could of been causing the needle to stick. Sure enough after barely loosening the screw up front that turns the pivot and spraying a small amount of deoxit, the meter loosened up. Since the meter worked, I adjusted it with the 1khz sine wave to get it to react the same as my right meter. I still need to get them set up correctly at peak volumes.
1.Will any harm be done If the meters aren't set correctly? I probably won't buy a new MM until this weekend.
2. I adjusted the DC offset to <1mv on each channel, but am confused how to adjust the bias. I have adjusted bias on other amplifiers before, but I was instructed a point on the power amp board to measure from to get the desired Bias reading. The service manual mentions using a variac, which I don't have. Can anyone instruct me on a simple way to set the bias?
Thanks again for all the help so far.
