This 80's circuit uses an audio amplifier to obtain a symmetrical source from a single source. The maximum current is on the order of 1.3 A and the input voltage must not exceed 20 V.
This power control for powers up to about 10 W uses wire potentiometers in an arrangement that...
This simple transistor test circuit was found in Radio Elecronics magazine from October 1961. It...
Another triggered oscillator that we found in the November 1984 Radio Electronics magazine. The...
