DUAL 555 VCO / MIXER

THOMAS HENRY DUAL 555 VCO + AUDIO MIXER

Thomas Henry's 555 VCO is probably one of the most precise analog VCOs ever, featuring ramp, triangle, pulse and sine outputs, sync, linear and exponantial FM, pulse wave modulation etc. Might be the best tracking VCO around.

Here's what Thomas Henry said about his design: "My favorite VCO of all times is the CEM3340, and I've always wanted to approximate it somehow. After nearly thirty years, I finally have a design which comes the closest. "
