"What power supply are you using? What is your voltage at the striped end of D4?"
- I'm using a Voodoo Lab Pedal Power 2 Plus. Voltage at the striped end of D4 is 8.58v.
"How are you testing signal?"
- I'm using my BYOC signal tester, my guitar, and amp. I don't own a signal generator or a scope.
"Any chance you've flipped any of the pin designations when reporting your voltages?"
- Here's how I'm taking notes every time I measure voltages:

"Clock pin 7 is the LFO input voltage. This is typically below 3 volts and you are showing over 7 volts. When you first reported your voltages you had less than 3 volts there. If you reinstall the original clock chip does that reading come back down to <3 volts? Is the depth knob at the same spot for both readings? Or does that reading go back down if your turn down the depth knob?"
- I reinstalled the clock chip supplied with the kit and the voltage at pin 7 dropped to 2.8v. The depth knob was the same for both readings but for good measure I checked to see if turning the depth knob changes that voltage and it does not.
"See what the voltages do when you reinstall the original clock chip. Try various combinations of the two chipsets that you have to see how close you can get to Stephen's voltages."
-The only combination of chips I had not yet tried was the replacement MN3101 with the original MN3007. It didn't fix the problem and my voltage readings were closer to Stephen's with the combination of the original MN3101 and replacement MN3007. This is the combination described with the voltage readings in the photo. Just in case it's hard to read my writing here's the voltages:
MN 3007
1-8.28
2-4.02
3-4.58
4-7.74
5-0
6-4.02
7-6.86
8-6.83
MN3101
1-8.40
2-4.05
3-0
4-4.10
5-0.39
6-8.05
7-2.81
8-7.92
"Once you get as close as you can, listen to the BBD output pins (7/8) while you slowly turn the trim pot to see if you can get any signal through the BBD."
- I found that when I set pin 3 on the BBD to 3.62v I do get a signal at pins 7 & 8. It's very distorted (buzzy, farty) but I do hear modulation in the signal and it changes with depth and rate adjustments. When I remove the signal tester and pug the output straight into my amp the distortion mostly goes away but so does the modulation. Even with the rate and depth turned all the way up the effect on my guitar signal is so subtle it's almost imperceptible.
