Commercial ballast tube in thermal regulating bridge is used with feedback-stabilized amp lifer and liter to regulate ac voltage source to 0.1%. Used for instrument calibration. Triode oscillator circuit oscillates al series resonant frequency of LC filter, which can be-tuned from 50 to 2,000 cps.-E.
