With the Astra. Video here.
I quote the creator:
“ken stone power supply board – caps/regulator/heatsinks/diodes from gutted wersi organ.
ray wilson’s 1v/oct single bus pcb. the keyboard is from a gutted lowrey wandering genie keyboard.
i recycled most of the capacitors in the unit from the genie and a dead tr606
(the rotary switches from 606 and a dead scope)
inside five small protoboards w/ 2 VCOs based on thomas henry’s 3080 vcos
(w/ matched transistor pair/tempco/polystrene caps).
white noise source (based on henry’s PNP noise source) through a Lm386 amp.
passive ring modulator using BAT56 schottky diodes – through their own lm386 amp.
VCF is a CEM 3328 from a dead mirage keyboard following jeff pointus/scott stites schematic – thomas henry 3080 VCA – a 555 based ADSR, two asm-1 lfos.
whew.
each CV section has it’s own modulation matrix rotary switch w/ choice
of lfo 1 tri, lfo 1 squ, lfo2 tri/squ, adsr, noise, gate, vco cross modulation
i didn’t buy anything for this unit.
i used some pretty crappy pots – but used good ones where it counts –
even the wire was from an old medical device
this is my depression era thrifter
the unit has linear FMs to the vcos and voltage controled Q
that are not even available on the front panel 🙂
i also built another lag in the unit – but didn’t need it…
someone can circuit bend it when i’m dead….
used decal paper for the first time to do the panel –
wood was dumpster wood
assembly of a mad man…”
But smarter than most mad men……and not afraid to part out crummy old combo organs. 😉
