Re: Help!Weird prob with "Super" DR clone!
You're running all the output tubes in single-ended parallel? What value are you using for the output tube grid stopper resistors? I'm thinking this could be instability caused by large differences in output tube transconductance during the warmup period, and if so might be eliminated by increasing the size of the grid stoppers.
