Hello, I've looked around and cannot seem to find anything on this problem. I purchased this receiver used and it works great. I have ordered new caps and will be doing a thorough resto on the unit when they arrive. However...... I purchased a Bluetooth receiver and I can hear a high-pitched static pulse coming from the tweeters on both speakers which disappears when I disconnect the Bluetooth receiver. Okay fine it's a bad receiver; but here is the issue. It doesn't matter if the receiver is on Aux or Tape, if the selectors are off and/or on other functions. The static pulse can still be heard. Is this cross leakage an internal problem? Do I need to fix something I'm not aware of, or will the recapping fix this? Thank you in advance.
