Barry	Re: Using 6EY6 in a Champ Thanks Bruce. That was more or less what I was after. I recall some concern over the ability of the power supply of the Champ to provide adequate levels of current using a 6EY6 for extended periods of time without blowing something in the power supply. Now, how do I go about adjusting the bias on this puppy? I know how it works (and do it regularly) with my Holland (think Bassman) but this looks like a different circuit and it is not obvious to me. More importantly, how do I do that without hurting the original condition of the amp? I have been running the 6EY6 for 20-30 minutes at a time. Although I do not notice any problems like excess heat and the like, I can't 'see' what negative effect this may be having on the amp so I am hesitant to leave it on for very long. Thanks and Regards, Barry
