I was turning on my adcom gfa-2 when it put out INSANELY LOUD NOISE through my newly restored speakers. I am still determining if it damaged the speakers themselves, possible tweeter destruction, but the thing is I have no idea why it did this.
I have never had a problem from my preamp or the source, the adcom has not been serviced as far as I know but it never did that before. There was something like 20 or 25mv DC offset per channel so it didn't sound unreasonably unhealthy. I have since used it on the speakers and it produced high end noise, making the tweeters make sound even when supplied nothing. What do you guys think did this? The RCA connectors on the back of the adcom seem to be a little loose, the outer connector to the ground inside sometimes lose contact it seems if I wiggle it and it is my completely unprofessional inkling that this might have had something to do with it.
Assistance would be greatly appreciated! Thank you.
