BRIDGED T AUDIO OSCILLATOR


Posted on Feb 7, 2014

Incorporates heavy degenerative feedback in which small lamp is nonlinear compensating resistance. Provides constant output frequency and voltage for any supply between 12 and 32 V, at temperatures down to -20 °F. Frequency is determined by capacitors C and 500-ohm trimmer control, to give choice of 100, 150, 230, and 350 cps. -H. P. Van Eckhardt,
