# Yamaha CS-15
“This item is being re-listed as the winning bidder was unable to complete the transaction. Up for auction is a Vintage Yamaha CS-15 Synthesizer. It is in 100% Fully Functional Operational condition. No noisy pots, switches, sliders or jacks. Cosmetically, it is in very good condition, perhaps an 8 out of 10. There is one small blemish near the Portamento slider, which appears to be a small burn, hardly noticable. ( See Photo ) The original case is also in very good condition with just a few small scuffs. The handle, hinges and latches are all intact and functioning. The Blue Velvet interior is near immaculate. ( When have you ever seen one of these in their original case ? )
Included is the owners manual, in a binder, with each sheet in protective plastic. Also included are all service diagrams, with large ( 11 X 17 ) diagrams of circuit boards, IC chips and components. Also included is some rare original sales/promotional material. This outstanding CS-15 has a three-prong power cord, and is rated at 120V, U.S., so no power converter is needed !
The Yamaha CS-15 is equipped with 2 complete VCO’s, VCF’s, VCA’s, and EG’s. In theory, it is two separate monophonic, or “duophonic” systems. There are also many sound source routing possibilities, which lends a semi-modular approach to sound synthesis. Please check out the reviews at harmony central or vintage synths for a more comprehensive understanding of it’s operational capabilities.” Link
