"This is an extremely early TVS-1 with serial #0017 built on 10-24-1975. The SEMS have been completely serviced and gone over, recapped and had all pots and switches disassembled and cleaned, and in some cases, the carbon resistive element was changed out for new.

This was originally a 1-voice system that had blanking plates that covered the sequencer and 2nd sem positions. I have installed the 2nd voice as the wiriing was already there for it. I do not have another sequencer to put in it though. I have seen one for sale online and could purchase and install it for an interested party.

The power supply has also been recapped and rebuilt. I have completely stripped and rebuilt the entire pratt read keybed and installed new lubricated bushes. J-wires have all been cleaned up and so the action plays like a brand new synth again."
