This circuit is from an article in Radio Electronics magazine from October 1958. The circuit is for testing electrolytics that operate at high voltages depending on the source.
We found this circuit in a 2002 documentation. It still uses old type plugs, but it can be adapted to...
This circuit was proposed by a 1965 Electronic Design. Its purpose is to widen the line transients...
The circuit shown can measure currents less than 1 uA and is powered by two 1.5 V batteries in a...
