With an output power of 1.5 W under a 12 V supply, this circuit makes use of transistors that are still common today. Power transistors must be mounted on heat sinks.
This circuit uses amplifiers from the 60's American company Microlin. The circuit can be designed...
This power control from Motorola's 1971 SCR Power Control Fudamentals can control full wave loads...
Despite being from a 1969 publication, the transistors used have current equivalents such as BC548 and...
