[sdiy] very simple VCA circuit

[Paul Perry]

I noticed long ago that the difference between a "happy hacker" (such as 
myself)
and a "real EE" (you know who you are!) is that the professionals always 
think in
terms of current. Things may have been different in the days of tubes - but 
I doubt it.
