Nice! Could you possibly share all the resistor and cap values you ended up using?

Those are the ones.

Those are the ones.

What about the 3uF output cap, the 22uF C3 and grid resistor?

3uf became .68uf (PIO) C3 is 22uf, grid resistor 2.7 I've been recording acoustic guitar using the 251 in this configuration with stunning results.

I used my Barbaric 251 (CT12, AMI 14/1) on acoustic guitar for the first time recently. Sounded good, but noisy as hell. Had to use a copious amount of noise-reduction to save my ass (really though, I had 2 other close mics and a pair of other mics further away). Guess I ought to try a different 6072 in it I suppose. Think I have another “good” one around besides another “bad” one and the one with a “bad” triode.

If you can't find a quiet GE6072 I would recommend the EH6072. The one in my FLEA is quiet and sounds as good as my 5 star GEs

Chris at Barbaric had mentioned to me back in 2017 how great the EH is too! Think it’s about time I buy a couple then! Thanks!

IIRC and just fyi, there was an EH-6922 in my former Innertube MagMic. The tube was quiet and sounded good. I'm not sure it was the original tube that Stayne put in (probably not, based upon the wording of the sale when I bought it 2nd hand), but it worked well in that circuit. Just a little experience with another Electro-Harmonix tube type.

Please forgive. 250M grid.
