klondyke transistor synth

no idea how it got the name klondyke – said i would post this when i finished it – months later… unijunction transistor based VCO scaled to keyboard (from dead juno106) – passive filtering either a warped sine wave or a weird pulse out via switch – output to passive ring modulator using old bat56 hot carrier shlongsky diodes – carrier signal is a multivibrator based around two transistors – switch to scale it to the same keys as first vco or free running – two knobs to tune the oscs – some switches – line out.piece of crapthat was the point – but i love it – slowly crawling out of my sound diy mental block (analness and dayjob)

Tumor Refilled Halo and 1934 Clough Brengle Beat Frequency Oscillator

HellFire Modulator Clone and Tube OscillatorThis is a picture of my homebrew Metasonix TS-21 Hellfire Modulator clone.  “Tumor Refilled Halo” is an anagram of the original name.  It is next to a 1934 Clough Brengle Beat Frquency Oscillator which works like a theremin in that it outputs the difference between two high frequency oscillating tubes for a very sweet sine wave, and instead of an antenna it has a dial for changing capacitance and thus the pitch.  There is also a home brew signal generator that I got on eBay.  The Two oscillators come together in the Frostwave Blue Ringer and their ring-modded output goes to the TS-21 clone.  That signal then is fed to a drum box and gated.  There is a demo file at  and the guts of the TS-21 are on display at
