This beautiful Yamaha is recently cleaned, checked, repaired by a pro. Brand Yamaha Model: P2050 Professional Series Natural Sound Power Amplifier Finish Black Year 1980s We are from J&R audio. Two 'hobbyists' who have been collecting and repairing 'older' audio for many years. Hobby that got a bit out of hand. With about 800 items, we think it's time to reduce the collection. Many products can be sold for a reasonable price. And this despite our professional way of working. Service has been provided on all our products, mostly by ourselves but also by our extensive network of many professionals with whom we have enjoyed working for years.Components that needed to be replaced have been replaced, strings in most cases renewed, as well as the lighting. Which in most cases has been converted to LED lighting. It is possible to give a warranty for many products. Ask about the possibilities. We also polish the hoods of record players and spray the outside of equipment or renew the paintwork of your speakers. We hope to be able to make many people happy with nice equipment. We put the proceeds into improving tools and equipment. And so we hope to continue to improve and to be able to continue this work that has arisen from friendship and hobby for a long time to come.
