This 12 V to 110 V inverter with 100 W was found in a 1977 Signetics manual. The transformer must be rated according to the desired power and the output transistors admit equivalents.
We found this circuit in an old documentation from the 70s. The sensor is an LDR that must be...
This low noise audio amplifier stage uses only one transistor and has a high enough gain to...
In fact, the 556 consists of a double 555, which can be replaced by these integrated ones. The...
