Default DIY F2 distorting BAD in one channel

Howdy


As of yesterday, my F2 has started distorting BAD. It sounds like it's happening mostly in then upper midrange.

It worked fine for years but then recently I decided to finally put a case on it. This required pulling it apart completely and putting it back together.

After being cased up it worked fine for at least a day. Now it's ****** in one channel. Prior to this, it had been on for a few hours, so my guess is that it overheated (since it's now in a case (ie less airflow).

Any thoughts what could be the cause? Ripping off the mosfets will be a [pain, so I'm curious if there's qany likely causes?

Thanks

Hugo

It seems to be getting worse, but I DID slightly fiddle with the wiring sometime before it went bad. Reflowing the joints will be the first order of business, thanks.
