Members gtrmaestro Posted March 9, 2010 Members Share Posted March 9, 2010 Just got an Epi Valve Junior head. Power light turns on but no sound, tubes don't glow either. What do I need to check? I really know nothing about amps or electronics but would love to fix this myself! Link to comment Share on other sites More sharing options...
Members Warhorse Posted March 9, 2010 Members Share Posted March 9, 2010 If You have some working tubes try a swap, but it sounds like a power supply issue to Me. Link to comment Share on other sites More sharing options...
Members gtrmaestro Posted March 9, 2010 Author Members Share Posted March 9, 2010 Would that be the transformer you think? Link to comment Share on other sites More sharing options...
Members Pepi Posted March 9, 2010 Members Share Posted March 9, 2010 Sounds like the heaters for the tubes doesn't have the 6.3 volts. Assuming you have the version 2 or 3 with the DC powersupply for the heaters I would check for voltage there. There are also fuses on the power transformer to check.

I guess I need to send it to an amp tech. Thanks for trying to help. Link to comment Share on other sites More sharing options...
