SV: Re: [sdiy] Rene's ms20 filter clone

[Karl Ekdahl]

Okay, to make sure of this a final time (i've been
wrong so many times before about this); a cap marked
"102" means 10pF * 10^2 = 1000pF = 1nF right? The
unfortunate thing is since i don't really understand
the principals behind a resonant filter, i don't
really know what to look for in the feedback circuit?

many thanks

Karl
