Help with an old ampeg v4b

A lot of these older Ampeg tube heads usually end up having a variety of issues, for various reasons. Bad tubes, dried out caps, and so forth. Maybe at some point someone has even attempted a mod or repair at some point. TB wise you might want to try an get in touch with Agedhorse for starters. Then branch out from there. Internet wise the Fliptops people sound like a place to start. Just a suggestion.

 

That’s a bummer. I love my 74 v4b. Best to take yours to a good local Ampeg tech. Don’t try to fiddle around in there yourself, and at all costs avoid touching the transformer—they can hold a significant charge for a while.

Small jolt from touching the metal sounds like a failed death cap which is a somewhat typical failure for the old V4Bs, and for sure needs to go to a qualified tech. Probably also a few other issues like others have said. Flyback diodes, fuses, random shorts, etc

 

This is a very good reason to leave the amp alone. There are lethal voltages present even with the amp unplugged. A tech is a wise investment and his/her price is much less that your life is worth.

Oh and ditch the Furman!

 

Amen X 2
