“Item:Roland JV-1080 Synthesizer For PARTS/NOT WORKING.
Powers up and SOUNDS AMAZING through the HEADPHONES but NO AUDIO out of the MAIN OUTS.
The ENCODER KNOB PUSH IN SPRING is OUT as well.
The the encoder knob needs to stay in the ‘out’ position or it slips to the ‘in’ position and advances by ten.
It still works though if you keep it from going in.
Does not come with any expansion boards, but I tested the expansion feature and that works.” Click here to visit listing on eBay
