Anyway I tried to lubricate the bearings of the tuning capacitor with silicone grease, lubricating the dial pointer rail, adjusting the angle for dial pointer.. well many things I did to come over this and none of them worked. Man I never-ever would have considered a dip of beeswax on the string would take care of this very very annoying problem.
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

Capacitor in Electronics
Alternating Current (AC): With AC, the voltage across the capacitor continuously changes. The capacitor charges and discharges cyclically. This results in an AC current flowing through the capacitor, with the capacitor acting as a reactive component that impedes the flow of AC to a degree that depends on the frequency of the AC signal.

How does a capacitor resist changes in voltage?
To see why it''s said that a capacitor ''resists'', or ''objects to'' changes in voltage at its terminals, it''s useful to compare its behaviour with a resistor (don''t confuse the ''resists'', meaning ''tries to stop'', with anything to do with the component ''resistor''). If …
