This is the power step of the previous circuit. Output transistors must be mounted on good heat sinks. The circuit is from documentation from the 60s.
This circuit makes use of an old Texas Instruments component. The buzzer is also from the era. The...
The resistors R determine the frequencies of the oscillator together with C. The circuit is from a...
In this oscillator circuit using 3 TTL inverters we have all the conditions for the frequency...
