Vintage Roland TR-707 Rhythm Composer Drum Machine with AC Adapter & Original Box Just Serviced Made in Japan

Up for sale is a vintage Roland TR-707 Rhythm Composer drum machine. I just had this unit serviced with my synth tech: the DC jack was replaced, all jacks had their solder touched up, system settings were restored, and all controls were cleaned. He also provided me with an aftermarket AC adapter that has the same specs as the original. This unit is in very good cosmetic condition, and includes its original box (solid structurally, but fair cosmetically). The unit was made in Japan, in 1985, serial number 534900. Check out the pictures.
