Tubes and Hybrids / AC30 VR doesn't produce sound.
April 26, 2016, 02:05:27 PM
My Vox AC30 VR hybrid amp's power light comes on but no sound is produced.  I can tap on the chassis and there is some static as if something is loose, of the capacitors one gets hotter than the others but there's no swelling or leaking.  The longer I leave the amp on, the more noise it makes as I turn it off. (a sputtering like sound.)  Tried different guitars but the same results.  Worked great one day and not at all the next.  There was no noticeable static the last day it worked.  We replaced the tube but no change and both the old and new tubes glow as it warms up.  Their are no burned spots on the board.  If I turn it on and turn it off shortly thereafter there is virtually no noise but the warmer it gets the worse we hear the noise as it turns off. 

Turing the potentiometers have no effect.  Strum all you want and nothing comes out the amp.  Any ideas on what to check?
