    I have a vintage receiver and it is has noise when I turn it on or use the different switches. I bought some tuner cleaner and used it to clean the controls. I understand one should clean the pots. How do I dio this??? I don't want to spend a fortune by going to a repair center if I could find one locally.

    IF THE RECEIVER IS VINTAGE THE POTS WILL BE EARLY CARBON TRACK OR WIREWOUND.IF THE POTS ARE WIREWOUND IT IS SUFFICIENT TO SPRAY SERVISOL SWITCH CLEANER INTO THE POT AND RAPPIDLY OPPERATE THE CONTROL.IF HOWEVER THE POTS ARE CARBON TRACK THEN THE BEST WAY TO CLEAN THEM IS TO DISMANTLE THE ASSEMBLY AND AT WORST RE-CARBON THE TRACK.THE TRACK IS VERY DELICATE AND HAS A FINATE LIFE SPAN.IN MOST CASES IT IS SUFFICIENT TO CLEAN UP THE WIPER.

    I take it such components for vintage receivers are not available off the shelf?

    (I wouldn't be surprised if they aren't)
