Tube Audio Designs

  1. I believe 12AU7’s are higher current, but less gain that 12AX7’s. Would it be possible to use a 12AX7 for greater gain, hopefully to achieve a higher output level? I’m trying to design a 6V6 PP mono guitar amplifier, but I suspect that your design (awesome as it is!) would lack the gain to function as a guitar amp that could play small to medium venues. Fifteen Watts output is kind of the target.

  2. Not knowing exactly which amp your comment is about, I would steer you to guitar amp examples. Audio amps usually don’t have the kind of gain guitars would need.
