Ok I'm having trouble with NF#2. Attached are the IC voltages. When I turn up the gain a bit it begins to howl, squelch, and make an awfully loud sound.
I'm including a dropbox link to show a video I took of whats happening.

I'm a bit lost as to what could be happening here. I have since rewired the volume pot as I had pin 1 & 3 crossed, but that didn't help at all.

Is R23 1k? Or is that 10k?

Could this be the vactrols misbehaving? How do I test them?
