Found in a 1970s American documentation, this circuit uses components from the era that can eventually be replaced by modern equivalents. The power supply must be symmetrical.
The presented circuit makes use of two hybrid modules (see articles on the website) to drive a...
With this simple tester you can measure the gain of an NPN or PNP transistor. The instrument can...
This circuit amplifies signals only in the frequency range determined by the double T. The circuit is...
