Epi Valve Jr. head won't fire up

[Jamie K]

Hey HFCers,

Any suggestions on trouble-shooting an Epi valve junior head that the power light comes on but there is no power going to the tubes (I say that because there is no glow and no warmth to the tube glass, and obviously no volume output). Is there a fuse or other obvious thing I should check? My main goal is to not electrocute myself...

Thanks,

Jamie K

Dangerous voltages inside. Download the schematic that is for your version (there are three, I believe) and follow the flow from the power trany. If you can't follow a schematic you should get someone to help you before you kill yourself. Because you can die even if the amp is unplugged. Or, start by swapping the tubes. Though it would be odd for both to be blown. Good luck but please don't take chances.

Good suggestions. Especially the precautionary ones. I will get qualified help before I go cracking anything open. Thanks!
