Fish fingers and custard!
1. Vacuum out all the dust you can from the interior. Don't touch the fins on the tuning cap!
2. Blow the dust out of the fins with compressed air. Don't touch the fins.
3. If you examine the tuner cap, you will see brass contacts at each point where the shaft passes through the metal housing. (Including where it passes through the internal walls.) These make the ground contact and they get dirty. Buy some NON - RESIDUE contact cleaner, and inject it into all these brass contacts, then work the tuner back and forth across the dial at least 20 - 30 times.
4. Then apply just a drop of CAIG Faderlube to each contact. It is better to use a syringe to apply it, rather than trying to spray a small amount. If you contaminate the fins of the cap or the circuitry, you will detune the circuit. Work the tuner back and forth 20 - 30 times again.
This procedure will cure all kinds of woes; noise when you turn the dial, certain stations not being received sometimes, when other times they come in clearly, etc.
