Clandestine Preamp

I ordered one of these PCBs. I am wondering if the 3 hole predrilled 125b from Tayda would line up since there are no 2 hole versions?

Thanks! I assume you select custom drill service and at the checkout, they will provide links to upload the drill coordinates?

I made my Aion Ares pedal w/ MPF4393 and it really works. I like Catalinbread's version, so added Bias knob and pre buffer out switch. I hate Fat mode, too. 47uF is unusable value. So I will try 10nF again.

This is my modded Ares version's schematic.

If you get a chance sometime soon, can you measure the voltage going into the circuit after the diodes and charge pump?

22.46V with a 9.37V supply.

Sorry, just to be clear, it does get bumped up to around 26V, it's the 22V Zener that brings it down to about 22V.
