"This synth was fully restored by my tech (RAMCUR on Flickr). He cleaned the black gunk off the circuit board and lubricated all the sliders and pots. He also did the following upgrades :

-Output has been changed to a 1/4" jack (from rca)
-Input has been changed to 1/4" and is now routed to the filter of filtering external sounds
-The polyphonic section now has its own output on 1/4" jack
-The filter's frequency can now be controller by an external CV input (on 1/4" as well)
-The envelope can now be routed to the osc 2 frequency for AMAZING SYNC SWEEPS!!!
