I'm needing voltage readings on three pins (trying to figure out a build issue and whether or not it is PCB related or something else). They correspond to IC1A pins 3 through 1 (the SIL op-amp). I've highlighted them in the red box in the image below. Many thanks in advance.
Well, I just ordered some boards based your schematic. Lemme know how this turns out. D'oh!

I may have a board fault but I'm not sure yet. I might end up breadboarding this partially to solve it.
If everything is ok, there will be Vcc/2 (plus minus). At output pin 1 surely, at - input too. Maybe at + input will be little less. If you power is 9V, there will be cca 4,5V.

Hey boss, did you get this worked out?

I'm having an issue here, too. I got no audio at pin 1. Di you get yours sorted?
