We found this circuit in a 1965 General Electric documentation. The circuit generates synchronized 400 Hz pulses. Modern components can be tested.
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...
