Amplifier

filament

Consumer electronics; Amplifier

The heating element in an electron tube, also called the "heater". The filament heats the cathode to a very high temperature to boil off electrons, which are then collected by the plate. The ...

filter caps

Consumer electronics; Amplifier

Filter capacitors. The term used for the large capacitors used to filter out the residual AC ripple in the power supply. The rectifier converts AC to pulsating DC, since it just allows current to ...

a method of biasing a tube or output stage by using a negative DC voltage on the grid with respect to the cathode. This name is sometimes confusing, because an amplifier may have a bias adjustment ...

flatness

Consumer electronics; Amplifier

the peak-to-peak deviation from the nominal voltage in the passband of an amplifier. Flatness is typically measured in dB. For example, if an amplifier has a passband "ripple" of + 0.5dB, it is ...

footswitch

Consumer electronics; Amplifier

A foot-triggered switch used to activate an amp’s reverb, vibrato, or other feature, as well as effects devices.

frequency response

Consumer electronics; Amplifier

The range of frequencies over which a device or audio system will perform.

full-wave rectifier

Consumer electronics; Amplifier

a rectifier that conducts on both positive and negative halves of the incoming sinusoidal signal. It produces a "pulsating" DC composed of single-polarity "humps" at twice the incoming AC frequency. ...
