So I got some JJ High Gain power tubes from Bob at Eurotubes (http://www.eurotubes.com great tubes) but I'm afraid to bias it 'cause I might explode or die or explode. Are there any places within 100 or so miles of Boston I can get the new power tubes installed and the amp biased? I've tried searching but I'm retarded or something. Or something. Please and thank you.
