I don't know how my reply was posted twice, but anyway, don't be intimidated, biasing the tubes is a piece of cake. It really involves nothing more then hooking up a meter that I believe paul provides and turning a screw until it reads the proper bias, and this only needs to be done on the power tubes, and only needs to be checked very infrequently or when you replace a tube. Talk to Paul at Bizzybee, He's a great guy and will answer any question you may have. if you cannot reach him via phone just email him, he's usually fairly quick to respond.
