Electronic Organ Circuit


Posted on Feb 7, 2014

This electronic organ circuit is very simple to construct and is basically an emitter-coupled oscillator composed of T2 and T3. An squarewave voltage can be sampled from the collector of T3 (X2). This signal gives a clarinet character to the tone. An additional vibrato signal can be added to this basic sound through switch S1. The frequency of the

vibrato is around 6 Hz. Its amplitude is determined by the R4. The value of R4 can vary from 100 up to 300K © but you can experiment with different values.
