I think that's pretty rad Curtis. It's obvious your builds aren't trivial, and I certainly have a ton of admiration for them. I'll take one of each :love:

I'd love to see PCBs and/or kits of any of your designs. :cool:

I am a total newbie so I won't be able to deal with your circuits for a while, but if I get to the point of feeling confident with my electronic abilities I would be more than happy to grab a couple of PCBs of yours

I'm cautiously optimistic that I may have resolved the power supply needs for the RMA Powerplant preamplifier (and other stuff that will benefit from bipolar power rails). I designed around +/- 24 volts at 100ma as the target for the discrete operational amplifier, but voltages will be downward adjustable for monolithics.

Seen depicted are some component footprints that I will integrate into the board level offerings (diode and non-polarized caps specifically), ultimately I'd love it if the pads reflect schematic thinking.

Now I just need to finish some builds so I can buy more boards, hahaha.
