We can use this basically a high gain amplifier with feedback circuit to cause the LED flash at rate determined by the 10u and 330k resistor. Before insert the unknown transistor, remove one of the transistor. The LED flash when it’s NPN with pins as shown in the photo. Remove one of the transistors to turn the unit off.

This article describes the Transistor Tester (NE602AN). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:NE602AN.
