Two Tone Generator Circuit

The final project as built.  All the modules are wired together to form this two tone generator.  In future designs, the blocking oscillator will be modified to give a much higher frequency tone.  The multivibrator needs to be slowed down a little also as the switching rate here is too fast.

Overall, the project was a success… the phase shift oscillator and the blocking oscillator with the transformer providing solid connection between the AC theory from unit UEENEEH114A and the practical soldering and construction skills in unit UEENEEH102A.
