MOTM

R68 is optional.  It is used in the circuit if you want to use 10V ptp
modular levels into the filter and omitted if you want to use 1V ptp
external levels.  I can think of obvious situations where I would want
to do both in the course of an evening's fun.

Has anyone oot there done a mod to switch R68 in and oot of the
circuit?  Where on the front panel would you recommend I put the switch?

Thanks in advance,  Greg
