6 FAQs about [Old style capacitor connection method]

How a capacitor is connected to a circuit?

In the equipment's chassis, often capacitors of different voltage ratings are connected by voltage-dropping resistors, and the equipment uses the current demands of the circuit to keep voltages in operating range. You could disconnect each capacitor from the circuit and reform individually, or perhaps follow method 2.

How do I reroute a capacitor?

How to reroute the wiring: you may have to unsolder the existing wiring and replace with new wiring long enough to reach the new capacitors, and route that wiring away from sources of hum (like parallel AC line wiring). Be sure to use wire that's rated for the voltages it will carry.

How do you replace a capacitor?

Hold the new capacitor near the place where it is to go, bend the leads to fit, and then trim the excess wire from the end of each lead with the wire cutters. Leave enough length on the lead to allow for crimping it around the terminal. Again, be sure to avoid leaving stray bits of wire inside the chassis.

What shape is a capacitor on a radio?

By convention, these shapes are a square, a triangle, and a semicircle. (In older radios, the can may lack coding and you will have to consult the radio's schematic to determine what each wire is connected to.) The following photo shows the value markings on the side of a four-unit metal-cased capacitor.

When should a capacitor be replaced?

But the capacitor must be replaced only when this drop becomes excessive. A simple way to evaluate the proper insulation of the capacitor is to remove the tube from its socket and measure the voltage drop across Rscreen, or VB+ minus Vload. If this drop is in the order of a couple of volts or less, no need to replace the capacitor.

How do you install a new capacitor?

New capacitors usually have wire leads somewhat longer than needed. Your first job is to trim these leads and bend them to fit the spot. Hold the new capacitor near the place where it is to go, bend the leads to fit, and then trim the excess wire from the end of each lead with the wire cutters.
