VCF / Passive Mixer

204D is a voltage controlled low-pass filter, which filters out the higher parts of the sound spectrum, and lets lower frequencies pass through. Based on "transistor ladder" design of Minimoog 204D, with a cut-off slope of -24 dB/octave as in various Moog synthesizers.
Resonance (or Emphasis) is adjustable all the way up to self-oscillation - in which case the filter behaves like a sine wave oscillator.
Works as passive 2-channel mixer as well. Handmade with thru-hole components only. Skiff-friendly.
