From the seller:

Yamaha CS-30 (analog synthesizer, released 1977). Yamaha's vintage monophonic analog synthesizer, the CS-30. A model released in 1977, with a 2VCO / 2VCF / 2VCA configuration plus an 8-step analog sequencer and flexible routing — a masterpiece of the CS series. Listed as I reorganise my equipment.

Operation and condition. All keys confirmed sounding and responding to the touch. VCO, VCF, VCA, LFO, EG, sequencer (including its switching) and pitch bend — the basic functions were confirmed to work without problems. There is almost no crackle in the knobs and sliders overall; comfortable to use. There is slight crackle in the headphone jack: noise rides on the signal if the plug is moved exaggeratedly, but it does not rustle on a normal connection or with slight movement. Considering its age (made in 1977) the gloss remains overall and the condition is quite clean, but cracks can be seen in the plastic parts on both sides. Please check the images for the detailed condition. No image processing or retouching to hide scratches or the state of the product has been done.

Contents: the CS-30 main unit. The power cable extends from the unit.

Please understand fully that this is vintage equipment from the 1970s. Apart from fatal faults such as no sound being produced, returns and refunds are not accepted.
