Yamaha PSS-130 Vintage 1987 Squarewave 32-Key Mini Key Keyboard Synthesizer / Drum Machine - Black IOB

Very cool little squarewave Yamaha keyboard. Unless they're new old stock I don't think these keyboards can ever be listed as mint condition cos the 2 vertical lines at the top of the face of the keyboard are like a dust magnet and terribly hard to keep clean. This one is actually rather clean in comparison to the other few of these PSS-130's I have, this one in excellent condition cosmetically, pristine working condition.

Includes original box (has expected wear and tear), original manual, and original warranty sheet.

Tested & personally cleaned, works perfectly.
No battery area corrosion.
Battery powered or 9-12V DC adapter powered (no batteries or power adapter included). 
If you would like a power supply matching the keyboard specs,  message me and we can add one for $15.

As the PSS-130 does not have a line out, if you would like it modded to have a line out send me a message & we can do that for an additional $20.

TableHooters: (fyi - not a typo that below starts out with PSS-30 specs)
