Members brokenfixed Posted February 11, 2013 Members Share Posted February 11, 2013 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.

Members riff ie Posted February 11, 2013 Members Share Posted February 11, 2013 I give all the tubes another tap w/chopstick, and never rule out speaker fatigue... idk Link to comment Share on other sites More sharing options...
Members GuitarSlim101 Posted February 11, 2013 Members Share Posted February 11, 2013 It certainly could be the tubes, but Hot Rod Devilles (and Hot Rod Deluxes) have a few other weak links that can cause problems like this. One of the main issues can be the 5 Watt resistors next to the bias adjustment pot, which have a tendency to get too hot and desolder themselves from the board or lift their traces from the board, which can cause intermittent noises and losses of volume. They also have a handful of resistors in the phase inverter section that have a tendency to open up, and a few resistors on the power tubes can go out, too. If those go, though, the amp usually won't make any sound, or will just produce a very quiet, very distorted sound. Another possibility would be dirty pre-amp out/power-amp in jacks. They're shorting jacks, so if they get too dirty or oxidized, they don't make proper contact. You can try throwing a short patch cable between those jacks and see if that fixes things.

Members brokenfixed Posted February 11, 2013 Author Members Share Posted February 11, 2013 damn, thanks for the info dude. I'll have to open it her up again and check it out. I guess I was leaning towards something associated with the tubes since Ive been in there recently and I havent had a problem with it until then. Although I didnt have a problem until I had it at a show, so is it possible something loose got looser? Link to comment Share on other sites More sharing options...
