- I had to fiddle with the board's PB amplification controls (R248/R148) to get a signal due to oxidation — I ended up using Deoxit. I now want to set them correctly, but I am unsure how to do it, as the service manual doesn't mention these pots. What are the test points and proper voltages? I already own a standard 315Hz 0Db calibration tape.
- For adjusting the PPM, it notes having 600 mV through 2TP2; how does one achieve this? Am I using a signal generator and injecting a 600-mV signal into 2TP2 (if so, what frequency), or am I playing a particular tape?
