The Heathkit IT-121 FET/Transistor Tester

Описание к видео The Heathkit IT-121 FET/Transistor Tester

In this video we'll look at a piece of vintage test equipment, the
Heathkit IT-121 FET/Transistor tester. I'll give a little background on what transistors testers are, the devices they can test and the parameters they can measure. We'll cover the specific features of this instrument, and look at the front panel controls and inside circuitry. I'll discuss the restoration of this particular unit, and say something about the circuitry it used. We'll see a demonstration of the tester in operation, and then wrap things up with a summary.
