Bogner Ecstasy Issue?

[joafink2]

I have a Bogner Ecstasy Classic that's been sounding under the weather. Almost sounds fuzzy. Decided to check the power tubes and they are drawing 3.5mA. Were previously biased at 25mA a few months ago. I put in a new set of power tubes to check and those measured at 1.5mA. What could cause the sudden drop in bias? I mean, I can't imagine the bias drifted that much on its own so my guess is there is an issue. Should I try to just rebias at a higher mA or is there definitely an issue here?

Before you go full open heart surgery, try a different cab.

Same thing with different cabs. Like I mentioned, bias previously was 25mA per tube. Now drawing 3.5mA and another set drawing 1.5mA.

You may have failing components in the bias circuit. This will need a tech if you haven’t troubleshot a components on a board before. Also an Ecstasy board may or may not be easy to work on.

Needs to be seen by a tech. I think you have something up with the bias potentiometer or something related to your bias. Could also be something else as well - no telling online.

Not an amp for a beginner to dig into. Way too much going on in there.

Maybe get or borrow a tube tester and test the tubes. It could just be a tube issue.
