I played my Ghia tonight for the first time in a while. Last time I played it it was making some odd noises -- sizzling static type noise. Worse on low notes, MUCH more obvious when driven. Tonight it was way, way worse.
I finally broke down and pulled out the chassis. I found at least 1 problem, for sure. The solder joint at pin 7 of one of the power tubes is completely gone. (It's the one with the blue resistor, not the one with the orange cap.) Also looks as if the blue resistor there partially melted the blue wire that attaches to pin 8.
I can fix the solder joint, no problems. If I wrap a piece of tape around the (partially melted) wire there will that hold me until I can get it to a tech? Anyone know any good techs in the DC, Baltimore, Annapolis area? Or does it really need a trip to the Dr?

Pull the whole filter out, both Resistor and Cap.
Replace the set of EL-84's as one is pulling too much currant.
E-mail me your address and I'll send you a new Conjunctive filter to re-install.
The amp will run fine without it, but the CF is a big part of the ghia's tone.
Probably before you owned the amp there was a bad EL-84 failure which damaged the CF, now with one bad EL-84 it overheated enough to come un-soldered.
A new CF and a fresh set of EL-84's and you won't believe it's that same amp.
