Members ksl Posted November 10, 2019 Members Share Posted November 10, 2019 Hiya... I'm trying to identify this amp component that, looking at the bubbling on the right side, needs to be replaced. I simply don't know what to ask for & where to look. FWIW, it goes from one of my old Gibson GA40's power tubes to some chassis mounted can. It's definitely not original & would like to make certain I get the correct thing. Thanks everyone! 🕉 Link to comment Share on other sites More sharing options...
Moderators daddymack Posted November 10, 2019 Moderators Share Posted November 10, 2019 there are a lot of parts there that look ripe for replacement...which one? Link to comment Share on other sites More sharing options...
Members Grant Harding Posted November 11, 2019 Members Share Posted November 11, 2019 That's a job for a professional. If you don't know what a dilithium crystal looks like you shouldn't be playing with high voltage. Link to comment Share on other sites More sharing options...

Thanks everyone! 🕉 The gold capacitor is the one I'm assuming you're referring to, since it's obviously burst (you can see "stuff" coming out of the right side of it, just below the orange wire). It is an axial lead, 100 microfarad, 150V DC capacitor. They're widely available and quite inexpensive. I have no idea if that's the stock component value or not. You'd need to trace the circuit and compare it to a schematic; there are plenty of GA-40 schematics available online. But if you don't know what you're doing inside an amp, take it to someone who does - it can be very dangerous, even fatal, trying to fix a tube amp if you don't know what you're doing!
