CENTER TAPPED TRANSFORMER AUDIO OSCILLATOR


Posted on Feb 6, 2014

The oscillator circuit uses a center-tapped transistor output transformer to serve as a load for the collector of Q1, supply a feedback signal for the base, and serve as the output winding for driving the speaker. R1 supplies dc bias and C1 completes the ac path from the transformer to Q1`s base. You can play around with the values of C1 and R1 to

change the oscillator`s output level and tone, but don`t reduce R1`s value too much or the transistor will draw excessive collector current.
