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?

Use the link from @PedalPCB above and save it under your Tayda Drill dashboard. After you purchase the enclosure and custom drill service it takes about 10-15 minutes for the job to show up in your queue in Tayda Drill. When it does, you simply assign the Drill plan to that job and you are good to go.

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?

I’m going to measure my Aion Ares and see what I have to. I’m trying to get some ideas for a higher voltage feed into a UniVibe style pedal and trying to keep a 9 vDC input.

22.46V with a 9.37V supply.

22.46V with a 9.37V supply.

Nice. I bet another round of diodes and caps would bump that up to around 25 vDC.

My Ares is right around 22 ish vDC as well.

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.

Even better. I didn’t have the schematic in from of me and forgot about the Zener.
