Hi FOR SALE I HAVE A YAMAHA PORTASOUND PSS-50 ELECTRONIC KEYBOARD. IT'S BEEN TESTED AND IT WORKS PERFECTLY. THERE IS NO POWER ADAPTER BUT IT HAS BEEN TESTED WITH A MAINS ADAPTER AND BATTERIES (BOTH WORK). YOU WILL NEED 6 AA BATTERIES OR A DC 9-12 V ADAPTER. IT'S IN A VERY GOOD PRE-LOVED CONDITION. COMES FROM A SMOKE FREE HOME. THANKS FOR LOOKING.
