This is not a vintage board; made for my own restorations and projects and offering leftover PCBs to whoever needs. Its a vintage-style photo-mechanically produced replica of the MK1 circuit, using all new-old-stock parts you’d find on an early 70s board (except the Philips electrolytic caps, still in production)
I matched the diodes, capacitors and transistors in the VCF and I think it sounds exceptionally smooth.
tested and calibrated, made with original 1970’s compliment of 2N5172 (w matched pairs in ring mod and VCF) 2N4288, BC169C, etc. Original TAB101 ring mod can, original fets selected transistors, NOS Iskra, Piher and Welwyn carbon resistors, Mullard tropical fish, original large Erie ceramic disks in the diode ladder (all matched). I can include a 32-way edge connector and pinout, wiring diagram, etc, if needed.
This board contains 2 discrete mic/line preamps, Germanium ring modulator, low pass VCF, and the auto-repeat Trapezoid Env/VCA.
