Andrew;

I'm back to the previous configuration now (resonator, stock values) and
have experienced the first "lockup" (which is insofar not completely
correct as the machine isn't totally locked up).

Symptom is garbage settings for the sound, simultaneously lighting A, 1, 5,
Manual LED's.
Turning the Cutoff control makes the LED shift between 5 and 8 (but that
happens only on the last few degrees of the turning motion.
I can not call up "Manual" again - except sometimes. It's as if the machine
is in some random "hiccup" mode now.

It took about 10 minutes for the lockup to appear.

I'll try now the cap between T0 and ground.
