I should call this project a cancer synth as it seems to grow uncontrolled. Whenever I find a cool module I either buy the pcb or components or redo the pcb. Having three different VCFs is a way to try out three different "sounds".
Each module consumtions around 10-15mA (from each plus and minus), but I have a few modules with on-board +/-15V regulators, that must be dealt with. One way could've been to supply each module with separate regulators and just source a raw, but filtrated, DC-voltage suitable for the regulators.
I've got the Neutron QVCA and must say I am as scared as when I drew thru Estes Park and over the Rockies 10 years ago - all components smt .... but four VCA-channels ... YUMMI!

I have ordered knobs and switches from them before, but they disappeared some time ago. Thanks for pointing out that they just seemed to have dropped the first word from their original name. Perhaps the PC police objected. For whatever reason they should have left the old web address active with a redirect to the new one.
I just use #12 copper house wire threaded through terminal strips like those found in 60's TV sets.
My modular synth also seems to grow in an uncontrolled, and somewhat unplanned fashion. I am also thinking about redoing the case yet again to better house and power all the different sized modules. Most are eurorack modules, often selected based on whatever board and panel kit I find on sale somewhere. I recently did a module swap with a friend in Florida and the Behringer Brains that I ordered a year ago has arrived. I also have a few small synths that I designed and build, and one somewhat larger one. The MFOS Ultimate, and Ultimate Expander are nearing completion. I have a Tsynth that is finished, but unmounted, and a PROGUE board and panel kit about half built, but still waiting for some semiconductors. The case currently holds four Behringer synths which I may separate out into a different case with the MFOS stuff and my old "Blue" synth. That still leaves the Roland JV-880 that I bought new 30 years ago without a home. It is a sweet sounding rack mounted jewel from the past, but it is 14 inches deep not counting the MIDI cables sticking out of the back. That makes for a deep case.
I got some low buck SMPS's from Amazon to power everything. A Meanwell RS-50-5 makes 5 volts at 10 amps for all the digital 5 volt stuff. Some modules have on board LDO's for 3.3 volts. I got a pair of Meanwell LRS100-15's for +/- 15 volts at 7 amps for the 15 volt supplies with localized LDO's to make the 12 volt supplies.

I guess that the new wife loved the switches, but not the name. I got knobs from the original company many years ago. They were about half the price for the same knobs from any music synthesizer or FX box related company. It looks like they are still cheaper than some of them. MPJA and Amazon have done better occasionally.
Maybe of interest here.

I think I saw your work on a different forum, beautiful amps, exceptionally well done!Maybe I presented these before, I don't remember...

Oh, yes - certainly...
Thanks@Magnuseklof !
Even maybe here, on my little, non-commercial web page :

Too cool for school, Daddy-O.My gallery of DIY 5-watters - with the exception of the SUPRO !

Aha : interesting... So they are not as perfect as they are claimed to ! I'm not surprised... The good old EI laminations are not dead !

Those amps look fantastic, how did you make the faceplates? I love the clean matte appearance.
DIY Fender and Ampeg Bass Preamp
I have always wanted a way to compare the 2 preamp styles:
The Fender is the Alembic/Showman/TraceElliot V-type/ style with switchable V1 cathode bypass caps(1uF, 3uF, 47uF)
The Ampeg is the second channel of the B25
The tone stacks are separately assignable.
The choices are:
1- Fender preamp with Fender tone stack
2- Ampeg preamp with Ampeg tone stack
3- Fender preamp with Ampeg tone stack
4- Ampeg preamp with Fender tone stack
Also added is a switchable MOSFET buffer as the first stage (similar to Alembic F1x and V-type) which could be used for an effects loop.
Mid-boost switch on both tone stacks.
The output is done with a mu-follower (5814 tube) driving a Jensen lineout transformer. This feeds a balanced input of a Hypex 2500W power amp.
Another DI output driven by a MOSFET buffer to feed a external Jensen DBE box.
All film cap power supply with Jan Didden’s T-regv5 voltage regulator set to 320V.
Very quiet, NO hum, lots of punch
A lot of fun!
