“Up for auction is a vintage Roland TR-707 in excellent shape. There are light scuffs on the front panel and scratches on the bottom panel. The front panel was recently cleaned of dirt and grime. Faders and tempo potentiometer were recently cleaned as well and work great. The battery cover on the back is missing, but there is no corrosion on the leads from busted batteries.
The TR-707 comes with an aftermarket power adapter. There is an issue where if the adapter plug is not in the right orientation then the unit will power off. It could be an easy fix, but I haven’t tried as it hasn’t been an issue when using it.” Click here to search for synths on eBay
