This is contact corrosion and a good contact cleaner (others may have specific recommendations--DeOxIt comes to mind) plus a thorough cleaning should restore these for a long while. Nothing wrong with the turntable, just the *&**&^^ RCA connectors. Also, using an extension cord on a phono cartridge is usually a bad idea. The preamp should be close to the cartridge. That extra cable rolls off your highs a bit. Cheers, Richard -- Richard L.
