Germanium Ring Modulator

On March 17, 2020October 19, 2022 By ctonnp

A good ring-modulator is a “must have” in any well equipped synth. I made this little design using four carefully selected germanium diodes as the exponential element. Germanium seems

News from the lab: Eurorack Synth!

On February 22, 2019October 19, 2022 By ctonnp

Back in the 1970’s I was thinking of a career in electronics for music, e.g. amplifiers, tape decks, speakers and most of all synthesizers. My career took a very different
