You can find a video demo of one posted here.

"Extremely rare monophonic italian synth made in the 70’s by Steelphon.
Completely serviced and ready to be used.
2 oscillators. White and red noise, very fast LFO able to modulate the 1st and the 2nd osc and the filter.
Classic Moog style ladder filter.
2 envelopes, 1 for the filter and 1 for the amp.
Unique analogue preset storage system, consisting of 6 boards with trimmers that control the parameters of the synth for 6 different presets.
Separate CV in for the 2 oscillators, V/oct and gate.
This synth sounds very unique and organic. It’s extremely rare, it is believed there is no more than 30 units in the world right now, probably 100 ever produced.
Used also by David Bowie."
