"New" Tube VCA

[McIntosh, Malcolm]

Hey great!

More tube stuff!  I will have to try both of your designs (VCO and VCA).

I have been working on a different filter but have not gotten satisfactory
results yet.  Gain decreases as corner frequency moves up the spectrum and
resonance is not there yet.  However, the CF can be swept from less than
10Hz to more than 20Hz.  More as it develops

Any one know a quick way to match tubes?
