This 12 V x 2 A regulator was found in 1965 Delco Radio documentation. The circuit uses transistors from that time. The input voltage can vary by 15% around the indicated value.
This circuit lets through the 300 Hz to 3kHz range that corresponds to the human voice. We found it...
This complementary circuit increases the output power of an operational amplifier. Outputs with...
