Just to clarify:

a) The MOTM-300 VCO uses ∗no∗ Spectrol 148 pots. There are 5 149 cermet pots,
and 1 Bourns pot. This pcb would ∗not∗ need a redesign.

b) the MOTM-310 uVCO uses 1ea 148 linear pot in the SHAPE circuit. Could I use a
149 as a replacement? Sure, would prefer not to because the cermet element is
"grainer" and there is a possibility of some noise when turning.

c) the 100K log pots are used for ∗audio inputs only∗ on the VCFs (420/440/480)
and the mixers.

d) I ∗prefer∗ to use 148 linear pots in some other modules but switching back to
149 cermet is ∗OK∗. In fact, I didn't start using 148 linear pots until the '310
shipped.

e) I reason I stopped using the 248 pots is the plastic bushings/threads were
easily stripped. But the issue is not 'conductive plastic', the issue is ∗log∗.
