I purchased a vr-405 years ago, have had it on 24/7/365 for years, litterally, and now I believe some component is going bad. It sometimes works when powered up, and will stay working until I try to adjust some audio settings that sounds like it makes the relays click, or if I turn the amp off and turn it back on. Right this second it's working fine, and I've bumped the amp around seeing if it could be a bad solder connection, but doesn't seem to be.
When powering on, it takes a few seconds like normal, and everything looks right, but there's no audio. I've done electronic repair before but not sure what part of the amp could be having problems?
Any information would be great, thanks
