The California Instruments Model 101T Power Amplifier is a solid state, high performance, low distortion power source that provides up to 100 VA output when used with the proper California Instruments Oscillator. The Model 101T Power Source is illustrated in Figure 1-1. Full power output is available from 105 volts to 135 volts rms and from 45 Hz to 10 KHz. For two phase and three phase operation, at least two power amplifiers must be combined together with the applicable multi-phase oscillator. Two power amplifiers will provide a total of 200 VA two-phase power, or 200 VA of three-phase power in the open delta configuration, Three power amplifiers will provide 300 VA of three-phase power in the wye configuration,
