all tranny vca+

[tomg]

As you guys know I've been working to put together a pile of
all tranny stuff  because frankly I'm tired searching for 13600s
and other DIY parts that are harder and harder to get.

BTW - From what I understand if you need CA3096s you
better get 'em while you can...anyway.......

This is an all tranny VCA. Here is another way to build VCFs 
opamps and VCOs too if you were determined. (I built one 
of each for fun). NPN pairs are 2SC1583s but the pairs can 
be hand matched.

Happy DIY
