"ultra rare modded Elka Twin 61 grey finish.

It's like having 2 Elka Rhapsody 610 in One with additional Fx and modulations.

I made a DEMO Video to show this synth in action [previously posted here]

In awesome aestetics conditions (just some little marks around)

100% perfectly working.

It comes with a MOD that let you play both A&B section without the original pedal."

"This is a one off custom Prophet 5 converted into a desktop format.
The keyboard and case were removed, and a new walnut case was custom made. As can be seen the leds were swapped out for blue , which (subjectively) is rather fetching. At this time the other important service was undertaken to prevent the well known failures of the prophet 5, rebuild PSU etc . A lot of care and attention went into this conversion. There would be no point in going to the effort here without overhauling the electronics.

The inside is a stock prophet 5 rev3 complete with 120 programs and factory midi, however factory midi has been disconnected and Kenton midi in installed (there wasn’t much value in installing thru/out since there is no keyboard , but it would be possible to connect these if you wanted to.)

the knob on the rear controls the amount of pitchbend received over midi"

Oberheim OB-Xa 8 voice w/ Magic Box (MIDI) SN 812130

via this listing

"OBXa in near-mind condition, with Magic Box external midi adapter and custom hard case (orange colour). I say near mint because there's some TINY cosmetic blemishes on the top edge, literally just paint thats been scraped off. No dents, even the paint is still flawless.

many many many hours and $$$ went into restoring the absolute beast of a polysynth. If you think plugins can even come close to this, you've never actually heard one.

-MIDI interface that didnt destroy the case or wood panels ($600USD) ()

-Power supply restored with new capacitors and bridge rectifiers.

-All voice cards completely restored, capacitors (electrolytic and film) replaced, and upgraded with multi turn trimpots.

-Keybed bushings replaced and keys straightened.

-Battery-less storage module installed (synthchaser.com), so no potential for leaky component destroying battery anymore...

Completely calibrated and ready to play. All kinks were ironed out one by one. It is, and I don't say this lightly, the most formidable synth I've ever played.

note - the knob caps are off in some of the pictures for cleaning - they're included :)"
