The electrolytic capacitors used in equipment of 1960s vintage contained liquid electrolyte, which dried out over decades, decreasing the capacitance and increasing the leakage current, and these are often the cause. One solution suggested is a "capacitor job", replacing all the old electrolytic capacitors.

The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead-acid car battery.
An alternative system used in automobiles is capacitor discharge ignition, primarily found now as aftermarket upgrade systems. [3] Electronic ignition was a common term for Kettering inductive ignition with the points (mechanical switch) replaced with an electronic switch such as a transistor.
A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...
The electrochemical charge storage mechanisms in solid media can be roughly (there is an overlap in some systems) classified into 3 types: Electrostatic double-layer capacitors (EDLCs) use carbon electrodes or derivatives with much higher electrostatic double-layer capacitance than electrochemical pseudocapacitance, achieving separation of charge in a Helmholtz double layer at the interface ...
John Muir (1918–1977) was a structural engineer who worked for National Advisory Committee for Aeronautics (NACA), who "dropped out," 1960s-style, to become a writer and long-haired car mechanic with a garage in Taos, New Mexico, specializing in maintenance and repair of Volkswagens. [1] He was a distant relative of the naturalist John Muir. [2]
A: preset resistor, B: preset resistor (alternate), C: preset potentiometer, D preset potentiometer (alternate), E: preset inductor, F: preset capacitor. In circuit diagrams, the symbol for a variable component is the symbol for a fixed component with a diagonal line through it terminating in an arrow head.
