Custom Prototype Synth Minim00g 1975


via this auction

"What you are looking at is a 100% analog prototype synth professionally built by a tech in the 70s who went on to building aircraft for Hawker Siddeley. The prototype was finished in the summer of 1975. The synth side is complete, really unique looking too. Reminds me more of a Sonic Six but does sound very close to the Minimoog. This synth is clearly based on the later. The keys feel nice to play and are in good condition. All knobs and switches are still intact. I had a tech look at it and they found some faults but does not stop this things power! It's a huge sound! E-Mail me if you want some sound examples. The tech upgraded the PSU with new kettle lead input and caps, cost £120 alone. He advised me not to go further with repairs so to keep it's originality. All that was done extra was fixing low output. But is easy to service if you want it done.

The faults found: Osc. 2 waveshape knob not working on wide and narrow rectangle waveforms. However on Osc. 3 they work just fine. Faulty knob on Osc. 2 no doubt.

Please note this is not a fault but; the drum module was never made for it which was a board that slots inside. All the electronics inside were built for the drum module but the board itself was never completed. You could perhaps have a board custom made if you want the drum section. The last lower 5 keys were assigned for this task so do not sound.

I had the synth up for sale before but decided to get some service done to help preserve it. They don't make 'em like this anymore! Full of top quality components unlike new Chinese toys. I've been as honest as I can be with this listing. I am an established musician and not a dealer. Local pickup is also welcome. Courier will be over £20 for full insurance. Worldwide shipping available but at new owners risk. Insurance a must! You also accept in the terms of this sale that the synth does require further servicing and is sold as non-working because of OSC. 2 knob fault. Rest of the synth is working sounds like a monster! It's easily worth over 2k for something like this. To have a custom built one now would run you near 5k easy. I'm in no rush to sell so please sensible offers only (ovno)"
