Yamaha DX27

“Yamaha DX27 Digital Synthesizer.

In perfect working order as far as I can tell.

Is missing the data entry slider cap but the slider is in working order and this doesn’t affect the functionality.

I haven’t tested the ports on the back other than the headphone output (which works) but have no reason to think that any of them don’t work.

I don’t have the power supply for it but it’s a standard 12v power supply so won’t be difficult or expensive to get one.

This item is in good condition, and I just played with it, and it plays fine and sounds fat.

This is the rare u.s. version with a 120v power supply. Missing a couple knob caps (as pictured)” Click here to visit listing on eBay
