Attached is a schematic of an audio amp that I've built, which was originally described at http://ludens.cl/Electron/audioamps/AudioAmps.html
I'm testing it by feeding it with 1Khz signal from a soundcard. I'm not getting any output from the amp. I lifted the connection from U1-6 and confirmed I'm getting good output from that first stage. As soon as I connect U1-6, I don't see much of anything from that point outward. I've double checked all the wiring.
I've got an o-scope and voltmeter. I don't have much experience with circuits like this output stage. I'd appreciate tips on what/where I should check and what I should be seeing.
TIA,
Barry
