Hey there, it's me again.
I built this one
https://tagboardeffects.blogspot.com/2012/12/runoffgroove-eighteen.htmlI don't have any 100K trimmers so I alligator clipped 9V+ > B100K pot > Drain on each transistor. I figured I'd get them set, measure the value on each pot, and drop resistors in there.
However, I'm not getting anywhere close to 4.5V on any of the Source pins (red voltmeter lead on the pin and black on the ground, correct?)
Here's what I get on each Source with the pots fully on (no resistance):
Q1 0.28V
Q2 2.04V
Q3 0.08V
and the pots fully off (100K resistance):
Q1 0.07V
Q2 0.67V
Q3 0.01V
Last note: I put jumpers between Vol 2&3 and Tone 2&3, just so I wouldn't have to hook up pots for testing.
Thanks in advance,
John
