My Hot Rod Deville is cutting out with a loud buzz and not passing signal, and intermittently popping here and there. It'll play for a while, then cut to a loud buzz and not pass signal until I turn it off and back on again and its fine for a while.
Whats the deal? I just retubed it a few weeks ago, and rebiased, rechecked bias yesterday and its looking good. Current amp knowledge spent. Learn me up some amp knowledge please.
