Quoted from EricHadley:I put a PinSound in my TSPP, now not only is the HUUUMMMMMMMM BUZZZZZZZ gone but I have SWEET sound!
I would have gone the Pinsound route, but after looking on their site, the only soundtrack for my Whitestar machines I have are the ORIGINAL, so I am going to solder in a dime's worth of resistors into R106/110 this weekend and save $350 on the pinsound for whitestar kit. Not as elegant, or fun, but an OK plan.
