Hi all. Picked up a distressed psr740 on Ebay. Actually it sounds pretty good but some of the upper keys don't play. Opened it and inspected the contact boards, didn't look worn just a bit dusty. Cleaned the contacts w/ no luck. Thinking I might have to buy the rubber pads. Any one know how to set the volume on the pads to bring them down a bit. Thanx
I have the service manual for this if you are interested. Just PM me if you are with your email address and I will send it to you.
