Capacitance Meter Capacitors, especially the electrolytic type used in power supplies as filtering elements to smooth the output power, are some of the most trouble-prone components of all. In addition to suffering complete failures like opens and shorts, capacitors can gradually lose their ability to store energy. Worse, their internal equivalent series resistance (ESR) can rise, in which case the capacitor will measure just peachy keen on a meter, but will act like it has a big resistor between it and the circuit when it’s in use.
While a little pocket radio might eat around 50 ma (milliamps), a power amplifier or radio transmitter may require hundreds of times as much current. For most work, if you have 5 amps available, you’re covered. There are some fancy laboratory-grade power supplies with digital metering, ultra-precise regulation, and price tags to match. You don’t need one. Any decent, hobby-grade supply will do. 8 volts, the actual voltage of a car with its engine running) supply with 10 amps or more is great to have as well.
Just be sure you can check that the instrument works properly before you plunk down your cash. Read Chapter 6 first so you’ll know how to test the scope. Look for a nice, sharp trace and no lines burned into the display tube, if the scope uses one. Along with the scope, you’ll need a pair of probes. Scope probes are more than just pieces of wire; they have voltage dividers in them and are specialized devices designed to permit accurate signal measurement. Most divide the incoming voltage by 10 (you’ll see why later) and are called 10X probes.
