42-380 Tuning capacitor makes popping sound

I've had this same problem. Sometimes teeny tiny little spots of rust or corrosion develop between the rotor and stator plates of the variable capacitor, causing an intermittent shorting as you tune through the dial. You may need to take some fine sandpaper and carefully slide it in and out between the 'fins'. It can be a real bugger to find exactly where they are touching!
