RE: Blown Valve Amplifier -(:

Posted by bcowen on November 25, 2016 at 13:58:15:

Not familiar with your amp, but some amps have a fuse (or fuses) on the B+ supply to the tubes. If it's blown, the tubes can still light up, just won't produce any sound as they have no B+ voltage. Check that first - the fuse(s) may be inside the amp requiring the bottom cover to be removed (be sure it's unplugged and off long enough for capacitors to discharge, yada yada).
