This 12.5 W quasi-complementary amplifier was found in a 1969 General Electric publication. Note the high supply voltage. Transistors are common types at the time.
This circuit was obtained from a 1962 magazine. It can still be mounted to be powered from 6 V...
The gain of this amplifier is 10 times and the excursion to the output voltage is 6.0 V (peak to...
This circuit consists of an adapter that allows the reading of low currents at various scales. A...
