[sdiy] EFM VCF2a

[tomg]

Going back to 1998-9 again maybe somebody
wants to build the VCF2a?

Don't ground the res pot, add a 50K trimmer in
series with the pot for peak trim and connect
the res pot to the .1 cap on the res input. You 
could change the .1 to 10uF on the out and res
inputs too. 

It's based on the Taurus but it's not a clone.
If you consider that at the time I didn't have
a clue.... It's amazing that I got it working at
all. Not that I have a clue now, just in case
someone wanted to say that... :)
