[sdiy] AC coupling caps on MS20 clone

[David G. Dixon]

Hey Team,

When are AC coupling caps necessary on filters?  Should they be on the input
and the output?  Should they be on all outputs of multimode filters?  Should
they be switchable?  What's the best value and type?

I haven't used them on my lowpass filters, but I'm unsure how to handle this
aspect of my 2164-based MS20 VCF clone design.  Any suggestions would be
most appreciated!
