This 50 kHz to 250 W circuit was found in an old RCA documentation. The transformer is a commercial type of the time and the output voltage is 80 to 90 V.
In the figure we have the CMOS logic test circuit developed with the 4049. The circuit activates three...
The oscillator shown in the figure keeps its frequency constant in an active cycle adjustment...
We found this circuit in a 70s RCA manual. The circuit uses an LDR by directly driving a sensitive...
