"This CS50 is absolutely beautiful, meticulously refurbished by us and in exceptional physical condition as well as excellent working order, unlike most. This process required approximately 20 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. Tuning trimpots were replaced to make tuning much easier and more stable. Logic ICs were replaced for longterm reliability. Oscillators were calibrated so this instrument is properly in tune. All key contacts were cleaned. All pots were cleaned and lubed."
