Crumar DS2 Vintage Analog /Digital Synthesizer SN 129


via this auction

"This is an amazing keyboard in many ways. It's one of the original series of Digital oscillator synths ( really analog controlled 74ls221 multivibrator chips. One for each mono osc and one for the poly organ which routes with noise and ext. input to analog mainboard. I documented mass info. on these. see my youtube tech vids). Only 150 or so of DS1 were made and it just lacks poly section and second LFO. They made I think a couple thousand DS2 maybe. MANY are badly rusted ( like my studio one I don't dare sell for fear of more troubles) This one however is pretty great. I fabbed a handle. I also spent many hours going over it on a few occasions and hopefully it's reliable now. The story is documented on my sounddoctorin site."
