Amplifier

inductance

Consumer electronics; Amplifier

The strength of an inductor. The unit of inductance is the Henry, or "H". Most power supply inductors, or chokes, are measured in henries, typically 2-20H. The inductance of a transformer primary ...

local negative feedback

Consumer electronics; Amplifier

feedback that is applied over one stage only, as opposed to global negative feedback, which is applied over several stages of amplification. An example of local negative feedback is a cathode ...

a phase inverter topology that has a single resistor connected as a pseudo-current source from the junction of two tube cathodes, with the outputs taken off the individual tube plates, one in phase ...
