Yamaha PSS-595 MIDI PortaSound Keyboard Service Manual ... For repair and for circuit bending!

This is a full service manual, with specs, panel layout, block diagram, dis-assembly procedure, test program, parts list, exploded views, circuit board diagrams and more! This would also work for the PSS-590, which is identical, just with some cosmetic differences. The PSS-595 is one of Yamaha's most advanced mini Porta Sound keyboards ever, and you'll need this to work on it! This booklet is in very good lightly used condition, and complete.

Modify / Circuit Bend it .... or fix some broken features, make it look pretty again or even bring back your PSS from the dead with help from this manual!

This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them.
