Erica Synths DIY Polivoks Eurorack Modular Synth MK1


via this auction

"This is a Mk 1 Erica synths Polivoks Eurorack kit built by me. LFO, 2 VCO's, mixer,VCF, 2x ADSR, VCA. Midi > CV is from a Pittsburgh modular Midi2. It is duophonic like the original polivoks. There is no power supply but there is a ribbon cable to power all modules from a standard Eurorack +/- 12v supply. It doesnt need 5v. The modules are in a Modular Studio EURORACK Rail & 19" Rack ears kit (this acts as a desk stand if you dont want to rack mount it. The modules are held in with 2.5mm screws and I'll provide a bag of spares. I've changed the ADSR's to give a faster envelope but this can be changed with 1 capacitor in each ADSR. VCO's track reasonably and could doubtless be improved with patience. I'll supply circuit diagrams etc but these are on the Erica site. This is real analog with Russian IC's and transistors, quirky waveforms and a proper Polivoks filter. If anything dies Erica can supply spares of the obscure stuff.

Erica synths are selling the Mk2 version fully built for 1600 euros so this is a bargain."
