This circuit was found in a 1966 EEE. The circuit uses transistors from the time but can be made with modern equivalents. The operating frequency ranges from 0.1 to 1 kHz.
This 600 W reducer uses SCRs and a switching system. The circuit is from Motorola's 1975...
We found in an old documentation how to use a 555 as a monostable key. The circuit should not be...
