"This is the latest version with working MIDI and test functions. Condition is very used but has gone thru some restauration from the outside, all knobs changes to aluminium type, clear coating and cleaned thruly. Battery has been changed and moved to different location, pcb has been re-traced at some place, all DCO/LFO side capcitors changed to new ones, several IC replaced with proper sockets, all pcb boards coated with proper pcb coating. Electronically device turns on, all lights turn on/off, switches works. Sound wise lfo is bit wild sometimes need some atention, makes sounds from 5 oscilators (6th oscillator works sometimes) but needs serious tuning."
