My charge pump has that link (as I recall), it is in your plans. All voltages look good, I am getting over 18v output.
I get audio signal at pin 3 of 071, but nothing at pin 6. And I tried a few different chips - all from a "new" tube of tl071s.
EDIT - also, as mentioned I am able to bias the trans to 9v, and I see them going up as high as 12+ voltage available at the trimpots. I seems to be the audio. Could be bad chips - would you recommend another opamp?
