  1. Blue Hawaii Special Edition

    If their are trim pots for adjustment then why would you indicate fixed bias is not adjustable? For "speaker" tube amplifiers, there are fixed bias amplifiers that are adjustable.

    Is the BHSE auto bias or fixed bias? If one changes the tubes for other EL34/KT77 variants (NOS or new production) is rebiasing necessary?
