Be sure to add me to your favorites list Original Yamaha PSR-150 PSR-75 Electronic Portatone Keyboard Owner's Manual Book. This is an original Yamaha User's / Owner's / Operating Manual for the Yamaha PSR150 and PSR75 model Portatone electronic keyboards. It's in very good condition, complete and very helpful if you have one of these excellent model Portatone keyboards. There are some minor marks in the booklet, but mostly on the covers, and the pages have no writing or rips in them. This book is in ENGLISH language. As a bonus, there are an added 15 songs of sheet music at the very back of the document as well. 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. Thanks for looking! Check out my Store!
