Great sounding power amp! My problem is that I can't quite figure out the proper way to bias these up?. They have 4 trim pots on the inside that led me to believe each power tube had it's own bias trimmer but, Doesn't seem to be the case or I'm just not understanding the do's and dont's of biasing this amp. Any help is greatly appreciated.
