(Hitachi) Lo-D HMS-30 Rare Analogue Synth with Manual SN 9000154C

via this auction

You can find video of one posted here.

"One of the rarest synth ever. As Internet says, only 300 was made. This one have a serial number 9000154C.

There is a full (all keys at same time) polyphony, two stage tone modificator, multilayered LFOs, 8-pattern rhythm generator, and programmable sequencer. Also, it have a stereo output, so it is possible to play with pan for some features.

Original user manual (Japanese) included.

Capacitors in power supply was replaced for prophylactic reasons, and output voltage precisely adjusted.

Pots and switches moves without any cracks or noises. The tune is fine.

Machine looks like a fully working, but I can not test all features of programmable sequencer (LEDs response correctly then I pressing buttons on it - thats all I'v figured out) because I can't read Japanese.
