[sdiy] Discrete VCA with 3046

[Tom May]

Checkout Jo"rgen Bergfor's VCA shootout:

http://www.idg.se/personal/bergfors/bergfotron/VCA.htm

Here's the summary for the 3046 circuit he tried:

  A clever design but has no real advantages over the LM13600.

  +:
    Low CV bleedthrough
    Fairly low distortion over a wide range of signal levels
  -:
    Fairly high signal bleedthrough

Be sure to check out the rest of the site, too.
