This circuit from an old MIT documentation excites an oscillograph element, an old waveform viewer.
This circuit was found in a 1977 Radio Shack documentation. The circuit is tuned to 1.4 kHz, but...
This circuit can source up to 1,000 V from a 9 V battery. Output current is very low, some...
We found this thyristor power supply in a 1987 documentation. It uses common SCRs as rectifiers and...
