What jfets are used? The 3819 has gate on pin 2 If you used something with a different pinout, like a 201 or 5457, that'll do it. You can test this theory by pulling the jfets.

Legs 2 and 3 are shorted Check leg 2 to 1 Even then, jfets/cap in the feedback loop may be giving a false reading

I recently picked up some of this chip quik no clean. The synthetic flux is supposed to be removable with hot (60C/140F) water I've been happy with the wetting and flow but haven't tried to wash a board yet.

Nice. Can this be utilized only when the varicap is to ground or can it be part of a larger network. Say, in a opamp feedback network.

Great minds...

You could decrease R3, try 4k7 Or decrease R14. You can temporarily add a parallel resistor to either with some alligator clips to see what works best.

In the $500 range, you can get a used Jericho. Great guitars, built by Cort I believe. I love mine.

Yeah some of the early Alahabra cali, pre shobud, builds had 2xMPS6513, 2N3397/MPS6513

2x NPN?

I feel dumb.

So, I vote we discect the next new user that stumbles across the workbench as well

This sounds like ground plane heat absorbtion

Keeley loves having one board for several products. Like he said. Not a pedal company, a manufacturing company.
