Thanks Frank. I really don't mean to "bust yer balls" but I have been over this build 100 times. I have re-flowed all joints, pulled on all leads looking for loose solder joints, double-checked continuity, layout, voltage, audio flow, etc.

I replaced all of the caps around the two ICs with electrolytics. I even took the cuts & links picture and flipped it horizontally so I could double-check my cuts.

It could boil down to the charge pump chip, I don't know. I do know I get that voltage drop at the 220R, and that I get no pin 6 audio output from the Tl071.

I guess the last thing I could do is post more pics just to make sure I did not miss something.

It is also my fault that I am not better at troubleshooting layouts to see if I see an error there. I say that because in your post you ask people to build it to verify it, so I am not sure if you have built this specific version yourself.

Can you link to the schematic?
