Members Bryce_dude13 Posted March 19, 2010 Members Share Posted March 19, 2010 Hey everyone. I have a Peavey Heritage that's having a problem. When I turn it on it hums very loudly then blows the fuse and then turns off. All of the tubes are in great shape and everything looks connected just right. It didn't do this until I opened it up the other day, but this has never happened before. I've read that it might be the filter caps.. They have kind of a brown color on the connections. Any ideas what it might be? I'm definitely going to take it to a tech soon. Link to comment Share on other sites More sharing options...
Members Shask Posted March 19, 2010 Members Share Posted March 19, 2010 I would assume tubes. That is almost always the problem with tube amps. The brown stuff on the connections is probably just flux, which would be normal. Link to comment Share on other sites More sharing options...
Members nakedzen Posted March 19, 2010 Members Share Posted March 19, 2010 First guess would be power tubes. Also, is your speaker cable in good condition? My Mako kept blowing fuses when I used an old cheap speaker cable. (Sound was coming through the speakers normally). Link to comment Share on other sites More sharing options...
Members Giga Posted March 19, 2010 Members Share Posted March 19, 2010 I'd take it out again and re-check whatever you were doing. You must have messed something up. The coincidence is too big I think. Giga Link to comment Share on other sites More sharing options...
Members NixerX Posted March 19, 2010 Members Share Posted March 19, 2010 Gotta be power tubes. Link to comment Share on other sites More sharing options...
Members Bryce_dude13 Posted March 20, 2010 Author Members Share Posted March 20, 2010 One of the 6l6's has a chipped middle(meaning the small plastic piece in the middle of the tube), I didn't think it would make that much of a difference. Could that maybe be it? Link to comment Share on other sites More sharing options...
Members the_bleeding Posted March 20, 2010 Members Share Posted March 20, 2010 Does it blow the fuse before you turn off the standby?- if yes, then something in your bias circuit is fried. Due to the delay, i'd bet that its the filter capacitor. Link to comment Share on other sites More sharing options...
Members Shask Posted March 20, 2010 Members Share Posted March 20, 2010 Mine did that when I had a bad power tube, but everything in the actual amp was fine. Replace the power tubes Link to comment Share on other sites More sharing options...
Members Bryce_dude13 Posted March 20, 2010 Author Members Share Posted March 20, 2010 It blows after I take it off of standby. Thanks for all the replies! Link to comment Share on other sites More sharing options...

Could that maybe be it? Unless you got that tube in the wrong way. That's what that key is for, to make sure it gets inserted into the socket the right way. Pull all the tubes and turn it on. If it's blowing the fuse after taking it off of standby, then it's after that switch and it could be anything. Link to comment Share on other sites More sharing options...
