Current Lover isn't loving the current. FIXED

I built up a current lover board and it's only putting out a clean signal, no flanging whatsoever.
Tinkering around I found that a wall wart will make the zener diode heat up, but with a fresh battery it's fine. I changed out the diode just to be on the safe side. Then I went through checking pinouts, polarity, and several cap and resistor values, but no love.

Here's the voltages. If a picture is needed I can post one.

I'm sorry sir, we only have the regular ohms

I've only just got back from a trip and i'm knackered but I think something is wrong at the BBD... I think it's causing it to draw too much current hence the over heating zener.

Pin 4 should be 14/15th voltage yet it has 16/15th voltage from the look... You perhaps messed up something with the 3007/3207 switching.

I have the jumpers vertically oriented like on the build docs. I was especially cautious to make sure I got that right.

I just spotted something I missed on the docs. I'll report back in a bit.

I am a total idiot. I missed the part that says to omit D4, D5, and C5.

The current is being loved good and hard. And going raw. ;D
