Seiko DS-250 with Power Supply Polyphonic Analog Additive Synthesizer

Very cool! Super rare Seiko DS-250 additive synthesizer.  Sounds better than you'd think. Really full sounding.  Plays great and all the controls work.  A few of the LEDs are weak or dead on the interval control and detune selector but it doesn't affect playability at all. There are a good few scratches, scrapes, and tape residue spots.  I have included some pictures of the worst of them.  Sold as-is.

The original power supply for this unit was lost long ago but I have tracked down a functional replacement. The power supply uses a 4 pin DIN connector and is very hard to replace.  Do not buy one without a power supply.  The power supply included is the correct voltage, amperage, and polarity and works great.  One more time though: NON ORIGINAL POWER SUPPLY!

I will ship within 6 days time.
