Hey guys, I built this ROG Supreaux Deux and the build couldn't have been easier. Seriously great PCB.
When it came time to bias it, though, I noticed that I could only get Q1 to 12v like the instructions say. I turned both other trimpots all the way up and could only get it down to 17v. I tested it and really did like the way it sounded, so I boxed it up and now i get a loud whine when I turn the pedal on. In addition to this, I believe my R11 (a 50k trimpot) might be busted. It has a smooth rotation for about 2/3 of it and then it locks up and is really tough to turn.
Why do you think I can't bias to the correct voltage for my other two transistors, what should I check? I'm going to go write the voltages down and post them in a few minutes.
