This 1.5 A circuit has the output voltages adjusted by a selector switch. We found it in a Popular Electronics from the 90s. The integrated circuit must have a heat sink.
This circuit consists of a single Hartley oscillator using a bipolar transistor that can generate...
We found this circuit in a documentation about SCRs from the 70s. The circuit can be implemented with a...
This circuit was obtained in an old documentation, making use of an operational amplifier of the...
