    Hello all,

    A technical discussion is presented on RC Phase-Shift Oscillators covering BJT, JFET and Triode-based topologies. The design of a 1-Hz sinewave oscillator using a 1629 Magic-Eye tube is comprehensively detailed and its usefulness shown when testing indicator vacuum tubes. Procedure for obtaining equivalent small-signal parameters for the triode section of the indicator tube is thoroughly explained.

    Best regards,
