Yamaha CS-5 Rare Vintage Monophonic Analogue Synthesiser Serviced! - 100V

The Yamaha CS-5 is a monophonic analog synthesiser introduced in 1979 and produced until 1983. It features a single voltage-controlled oscillator (VCO) that offers pulse or sawtooth waveforms, as well as a noise generator. The synthesiser includes a multi-mode filter with 12dB/oct high-pass and low-pass modes, and a 6dB/oct band-pass mode. It also has a low-frequency oscillator (LFO) with sine, sawtooth, and sample & hold waveforms. The CS-5 also allows external audio input, which can be routed through the filter and amplifier sections. Known for its warm analog bass and synth effects, the CS-5 has been used by artists such as Siouxsie and the Banshees, Depeche Mode, Richard Barbieri, and the Sneaker Pimps​


• This CS-5 has been used. 

• This CS-5 is in good condition for a approximately 45 year old synthesiser. There are some signs of wear like some marks, nicks and scratches. There is some surface oxidisation on the faceplate as well as some screws. Under the keys and on the bottom show some larger sections where the black colouring has come off. Although not physically perfect, the unit has had a though service and is still an awesome sounding piece. 

• This CS-5 has been serviced. All pots and switches were cleaned, any faulty components were replaced and the synth was calibrated to factory specs. 

• This CS-5 has been thoroughly tested after its service and we can confirm it is 100% functional. It has no faults to note. 

• Please be aware this unit is 100V. This means it MUST be used with a step-down transformer, not a travel adaptor. If you are unsure about this please let us know. We have some great, compatible step-downs for sale HERE. They are designed in Australia for use in Australia and can be run 24/7.

• If you purchase from outside Australia you may need a step-down transformer to use this unit. Please contact us if you need any help sourcing the correct product.
