Amplifier

cathode

Consumer electronics; Amplifier

The "current generating" element of an electron tube. The heater heats the cathode to a very high temperature, causing it to emit electrons, which are then collected by the anode, or plate, which ...

cathode biasing

Consumer electronics; Amplifier

A method of biasing a tube where the bias is generated by the voltage drop across a resistor in the cathode. The grid is referred to ground through a resistor, and the current flow through the ...

channel switching

Consumer electronics; Amplifier

A feature that allows an audio signal to be routed from one channel to another, usually by means of a footswitch.

chassis

Consumer electronics; Amplifier

The box metal frame to which electronic components (capacitors, transistors, resistors, etc.) are mounted.

choke

Consumer electronics; Amplifier

Another term used for an inductor, most commonly an inductor used as a power supply filter.

circuit breaker

Consumer electronics; Amplifier

A device found on the backs of some amplifiers that automatically interrupts a circuit carrying potentially damaging current; often used instead of a fuse.

Class A

Consumer electronics; Amplifier

an amplifier operating with the grid bias adjusted so plate current flows for the entire 360 degrees of the input waveform, by biasing the tube halfway between cutoff and saturation, in the most ...
