Vintage Yamaha DX7 Digital Programmable Algorithm Synthesizer Synth Keyboard Made in Japan Just Serviced

Up for sale is a vintage Yamaha DX7 Synthesizer keyboard. This one was just serviced by our tech and plays great. It had a full tactile switch replacement (42 tactile switches were replaced). The onboard battery was replaced with a socketed battery (CR2032) that can be replaced by the user. This unit was originally sold in Japan, so the previous owner modified the power supply to a step-down transformer, that is rated 100v; /- 15v rail 5v. It comes with the Yamaha Data RAM cartridge. The unit shows some cosmetic wear, but this is a very good working synthesizer since the service. Check out the pictures for the condition. The keyboard was made in Japan, serial number 101026.
