Yamaha CS50 For Sale. This unit was meticulously serviced and in excellent working order, unlike most. This process required approximately 15 hours of skilled labor. The power supply was rebuilt as a precautionary measure, in an effort to extend this units life well beyond others you may find. The oscillators and filters were calibrated so this instrument is properly in tune. All key contacts were cleaned. All pots were cleaned and lubed. The felt under each key has been adjusted. The keys were removed and cleaned. This unit looks great, works great, sounds amazing and is a real pleasure to play.
