I recently purchased this from the original owner in Italy. It is in incredibly wonderful shape and I absolutely hate to sell it, but it's just too big for my space. It sounds awesome. It was out of tune when I received it and I had it professionally serviced to fix the tuning and clean up any other minor issues. This runs on European 220V power so you will need a step up transformer (can be found very cheap on Amazon) to run on 110/120v in the States.

There are a couple of minor scrapes on the control panel as seen in the photos and small bits of wear on the edges of the end panels. This is a 40-year-old piece of equipment, it's in wonderful shape but please keep in mind that it will need upkeep and may need servicing after transit.

Here's the general info about this awesome synth:

The Crumar Stratus in 1982, it's a 6-voices polyphonic analog synthesizer + organ synth which can be played separately or simultaneously.
 
SYNTH SECTION

The Synth section implements two 74LS221 oscillators (the same used in the ultra-rare Crumar DS-1) with saw, square and saw+square waveforms. The two oscillators can be synced or tuned separately. The Synth architecture is basically built around CEM chips and in fact it features 6 CEM VCFs, 6 CEM VCAs and 6 CEM EG (one per voice). The CEM filters and envelopes, combined with the various oscillator features, make it possible to create a wide range of electronic pianos, lush strings, quasi-vocal pads and tuned percussive sounds. A very unusual (unique?) feature is the "Alternate" switch: this automatically switches between sawtooth and square on every key depression, or only after all the keys have been released and one is depressed again.

ORGAN SECTION

The Organ section implements two additional detunable (or syncable) master tone generators divided-down to generate the octaves of the 4 horizontal drawbars (2', 4', 8' and 16'). The fact that the two master Organ oscillators can be detuned allows to produce a vast, rich, organy sound. The Organ section is fully polyphonic and can benefit of the Glide effect and the LFO features. The Organ audio output can be taken separately from a ¼inch jack socket on the back panel, or from the socket marked 'Polysynth' which in fact gives a mix of synth and organ if used alone.
