All resistors & ICs are smd, caps & transistors are thru-hole. This is for the cellF neural synth project, which will have 8 of these voice boards. 2 tri-core VCOs, 2 LFOs, 2 LPGs, 3 VCAs, VC spring reverb, diff-rectifier, jerkoff chaos, 2 281 EGs, Sauce of Unce. Pots and sockets mount on PCB. If people are interested I will get some extra PCBs and Euro panels when vers.2 is made (no doubt vers.1 will have errors).
