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.

Post a pic of the top and bottom of your build, please.

Pictures attached. Thanks for your help.

Do the pictures reveal anything?

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?

R23 is 1K

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

[oldsoul]

This one has me stumped as well.

[oldsoul]

Just trying to get back to this. Any ideas on where I should start to troubleshoot this one?
