Questions about tubes and gear that glows. FAQ

EL34 and 6U8 tube rolling.

How about tube rolling a Sophia Electric EL34 amp (not the Baby)?

The amp comes with current US label Svetlana's (?New Sensor sourced). The amp, which I have yet to open, relies on variable resistors for biasing the tubes. I guess this limits or makes biasing more difficult. How do you bias the tubes?

EL34 suggestions?

Can you use the JJ KT77 tubes in this amp? Sophia Electric seem to advise against it!

What about the 6U8 input tubes?

Any input appreciated.

Thanks.

Sincerely,

Hany.
