Skip to main content. The beat generator is also a programmed divider which contains 15 available beats. It has an inbuilt tone and a beat generator. Here the musical IC UM66 generates the music when it receives supply and drives a small speaker through a class c amplifier using silicon transistor Datasheey. You need off voice recorder circuit interfaced with a amplifier circuit.

It is better that you should not run this circuit in Eliminator as most of the available eliminator don’t have a good filter built in and have no precision over voltage protection. Resistor R1 limits the base current of Q1 within the safe values.
