Hi, this is my first post on quadraphonicquad. Last summer I acquired a Sansui QRX-6500 from the side of the street, left for free, in pretty decent condition. I let is sit in the house for a could of weeks, on the chance of any moisture to dry up, I plugged it in, and no shit it worked! What a really nice tuner section! I did find a small amount of saw dust when I cleaned the pots and slide switches. Ended up replacing all the electrolytic’s on both the intermediate and main pwr supply boards, after checking all components. The service manual I have, doesn’t show what output voltage for the adjustment. I read online. 25 volts at pin fifteen? Is this correct, if so , can you direct me to that pin? Or other procedure?
