12U7 (not 12AU7) headphone amp circuit
Posted: Tue Aug 04, 2015 10:01 pmAfter spending a few years just working off PCBs, I've decided to go "skinny dipping" and try a point-to-point amp.
Thought I'd start simple and do a little hybrid headphone amp.
This circuit was designed for a 12AU7, but to be honest i don't think 12v on the plates of a 12AU7 will do anything.
Luckily, I have a spare 12U7 http://frank.pocnet.net/sheets/137/1/12U7.pdf
The circuit is attached.
Can anyone assist in determining what resistor changes I'll need to make to adapt it to the 12U7 tube?
