I have a new module. This is just a Kosmo format adaptation of the Barton JFET Phaser .

Front view of a synthesizer module, 5 by 20 cm in size. There are three pots (Frequency, Resonance, and CV Atten), four jacks (Signal, CV, APF, and Phaser).

And yes, once again JLCPCB failed to honor my request to put the order number in my specified location.

I assembled the PCBs following Barton’s instructions, except I omitted the board mounted pots and jacks. (And, as I usually do with Barton designs, I used 100 nF for the bypass caps, and 1N5817 Schottky diodes rather than 10Ω resistors on the power rails.) Instead I used panel mounted components and wired them to the PCB footprints. I mounted the PCBs to the panel with a sheet aluminum bracket clamped between the panel and the bottom two pots.

It all appears to work, so it’ll go in the Kosmodrome case soon. The front panel design is available at https://gitlab.com/rsholmes/frontpanels/-/tree/main/Barton_JFET_phaser .
