This simple source uses two 2N3055 transistors that must be equipped with good heat sinks. The source has no protection, only an input fuse. The diodes are for 5 A x 50 V or more.
This simple circuit makes use of a buzzer with a 6 V oscillator, compensating for the 2 V voltage...
In the figure we show another configuration for a crystal-controlled overtone oscillator using a...
The circuit that we give below has two possible applications: it can be used to control a lamp...
