“Really neat vintage synth, in great working condition. I restored it electronically 3 years ago, and have only used it in my home studio. I’m the second owner, and acquired it directly from the original owner whom purchased it in the 1970’s, I believe it’s from 1976. I have a bunch of paperwork for the synth somewhere, if I can find it(I’ll try, it’s buried in boxes somewhere!) I’ll include it as well. It’s worth noting that during the restoration, I preferred to keep the synth as original as possible, but electronically stable, and to make a 50 year old synth as reliable as possible. It includes and uses the original “pin” cables, so neat & rare. That being said, it’s still a very old synth, from the early days of modular synths, when slight changes in mains voltage and temperature variations manifested themselves in “interesting” ways. I’d assume that the purchaser of this synth understands that and doesn’t expect the oscillator tracking and tuning stability to be similar to modern synths. Please watch the Youtube video I created for this synth, which goes into great detail about the synths condition, and should answer any questions you have, and give you a clear idea of what to expect if purchasing.
Thanks!
