The design used triodes as phase inverters and drivers.
2.
Power Damping is a method of output level control that involves the phase inverter and a potentiometer.
3.
More complicated SVM strategies for the unbalanced operation of four-leg three-phase inverters do exist.
4.
The second triode is a phase inverter, which creates mirror images of the signal to drive the output tubes.
5.
A basic three-phase inverter consists of three single-phase inverter switches each connected to one of the three load terminals.
6.
A basic three-phase inverter consists of three single-phase inverter switches each connected to one of the three load terminals.
7.
The potentiometer allows that stage to be overdriven at reduced output similar to a Post Phase Inverter Master Volume ( PPIMV ) control.
8.
It is often used in guitar amplifiers ( where it is referred to as the " phase inverter " ) to drive the power section.
9.
The Harvard was a fixed bias amplifier, using a basic cathodyne phase inverter, but did include a selenium rectifier in the bias circuit.
10.
These are referred to as the 12AT7 tube as a phase inverter, and individual Treble and Bass control knobs rather than single tone controls for each channel.
