Yamaha Portasound PSS-780 Electronic Keyboard 

Thank you for your interest.

This is a YAMAHA PSS-780 released in 1989.

The main unit and AC adaptor are included in the set.

The instruction manual is included in the package.

You can download it from YAMAHA's website.

It is an old item, so it has some fading and minor scratches.

When changing the volume with the volume slider, a burr sound is produced.

We have checked that all keys and pads play sound.

We have not checked other functions of the instrument, because it was only connected to a sampler to play sounds.

Other functions have not been checked.

Please check the photos for other functions.

Please do your own maintenance such as repair.
