AS90 Posted March 10, 2009 Share Posted March 10, 2009 I haven't used my GA5H for a few weeks, I turned it on last night and nothing happened! The power light is on but there is no output, any help? Link to comment Share on other sites More sharing options...
m-theory Posted March 10, 2009 Share Posted March 10, 2009 Put your logic hat on, and use your head. Start eliminating things, one by one. If you haven't already done so, just plug the guitar straight into the amp. Try a different cord. Try a different guitar. Try the speaker with a different amp. Try the most obvious of things, such as amp standby switch and speaker connection. Finally, if it's none of those, it's probably the output tube.

AS90 Posted March 11, 2009 Author Share Posted March 11, 2009 ^ Yep, its none of those. The tube doesn't glow either. Which one is the output tube and will I kill myself getting it out? Link to comment Share on other sites More sharing options...

One of the reasons I turned all my VJ heads upside down...(besides the better heat dissipation). Link to comment Share on other sites More sharing options...
m-theory Posted March 11, 2009 Share Posted March 11, 2009 First, check the heater fuse. The orange wire has a fuse on it. Open that up, sand the ends a bit, and put it back together. Sometimes, a varnish on the ends of that fuse prevent it from making contact, and it will do what you're describing. The output tube is the taller of the two.
