This white Tom Oberheim TVS-Pro -- or Two Voice Pro-- is in immaculate condition with no issues whatsoever.
Both SEM's tune perfectly and hold well through hours of use. As you can see, the patch panel really expands the capabilities allowing you to route velocity to different places for example.

Tom Oberheim himself said these were made from the exact same schematics and electronic parts values from the originals. While I haven't tried this myself, apparently an original SEM from the 70's can work if you swap them out.
I have used it mostly in "dual mono" mode for the world's best stereo mono synth lines. Duplicating the settings on both SEM's make this a huge stereo sound since each SEM is analog and slightly different. It is in my top 5 synths of all time.

There are less than 250 of these in existence and perhaps the best version of a Two Voice.
This one has been used less than 4 hours. 
It has the final firmware updates: Keyboard v24a and Seq v30 from 2018
It will come with original manual, and power cable.
Only selling because I have three of these including a black version and I'm deciding which one to keep.
