Some KT88 amps advertise that they can also use EL34 tubes. My Melody M880's owner manual does not say anything about EL34. Can I use EL34 tubes, instead of KT88, and just lower the bias?
Does your manual say anything about alternative tube choices? Sometimes you can substitute, and sometimes you can't, I think it depends on the circuitry among other things. Perhaps you should contact Melody.
I sent email to Melody last week but have not received any response so far. The owner's manual does not mention anything about alternative tube choices either.
