"This is a great example of a four voice. This unit was restored recently, with rebuilt power supply and decoupling caps replaced on all boards, pots cleaned, keyboard bushings replaced and entire keybed cleaned and polished out, and oscillator tracking calibrated.
It plays and sounds incredible. Only issues are that the master volume pot is a little scratchy (only when adjusted), and memory store/recall does not work properly despite replacement battery. Memory storage on this keyboard is not very useful anyway - since some of the most important settings cannot be stored with a patch by design (modulation routing, etc.). The more useful features of the optional programmer module all work perfectly (vibrato, centralized pitch, filter control and envelopes). Tolex is original, and some bumps, bruises and rips have been professionally touched up (worst of it was on the lid)."
