Anybody that bought a PCB from OLcircuits for the DB before he pulled them and is having a problem, there was a 5nF from the 9v to ground by the second FET that was left out of gringo's layout that apparently is real important!

I used a .0047µF that I soldered to the rail and then to ground. I can now turn up all the knobs all the way with no SQUEAL.

I'm happy for the 1st time in days dude.

I came home from work yesterday in my hot van only to find a hot house. My air had gone out during the day and it was 95 out. They told me my air's shot and I was bummin' but this makes my day. I've been working on this for a week at least.

COOL.

I'm glad to hear ya got it under control and it's working the way it should. I used the original Bucksears / Electritabs design and made my circuit board. I think in my case, I just had my 9v power wire too close to some of the pots wiring, which I didn't follow very good practices with as my leads were pretty long. Once I spread mine out in the 1U case, all my squealing disappeared. I love this box and wouldn't trade it for anything, but also love the JCM800 every bit as much.
