I would advise just setting the one turn trimmer to mid span and adjust
the 20T for 2KHz. This is hardly critical to the TM operation or sound.
The delay CV is exponential mostly for ease of adjustment.
I had a chance to try out the J, Larry Hendry negative voltage clamp and
it works fine. A good solution; but where to add it on the board next
rev???? Very tight.
