For anyone interested in Turing Machine modules, I’ve just uploaded a KiCad schematic and PCB layout for the Worng TM-LPG-X lowpass gate module to GitHub. The PCB has a couple of custom footprints allowing the capacitors of the LPG to be replaced by resistors (as in a Vactrol Mix) or by pin headers to connect to a panel mounted DPDT switch to swap between these modes. The Rs and Cs are mounted on the switch in this case.
There’s also a design for a daughter board which allows an LPG (or a Vactrol Mix) to be connected simultaneously to both the PULSES and GATES headers of the parent Turing Machine. A switch and a gate CV input (active when the switch is OFF) control which of the connections is active. Together with the R/C switching this gives 4 modes of operation - either LPG or Mix, driven by either PULSES or GATES.
No pictures as yet I’m afraid - I’m rather behind making panels for my current batch of modules…
