Hopes everything going well, Barry.
Cybercow, I’ve pushed the ICs a little bit and seems to be well located on the sockets. No sound differences when pushing.
Wilkie1, i’m using a programmable power supply with 9.0v in the output. I’ve checked from off to 9.5 volts, interesting different sounds there but not an autowah. For me sounds like a wah or filter but in a fixed position. It seems like It is not changing according to input volume.
PCB and all components are from a musikding kit. I think IC1 is from national semico.
