Both windings are 40 turns so it does not matter which winding is used for the primary or which is used for the feedback. The phase of the transformer winding must be correct to get the circuit to oscillate. There is only one trick to get the circuit working.

The project uses a single 1.5v cell and this voltage is below the 1.7v needed to illuminate a red LED so no power switch is required.

The two LEDs in series are used to produce a voltage greater than 1.7v + 2.3v = 4v so the 4v can be used to illuminate a white LED placed on the 'Test LED' pins. It's a flyback transformer that produces a high voltage when the transistor switches off and this voltage is used to illuminate a single LED for the PNP transistor and 2 LEDs for the NPN transistor. And, amazingly, it only uses a few components. Some provide the gain and even the maximum operating voltage but in most cases we only want to know the c, b, e pin-out and if the transistor is NPN or PNP. There are lots of transistor tester circuits on the web and they all do the one thing - identify a PNP or NPN transistor.

Transistor Tester Transistor Tester To buy a kit: There is a certain amount of skill required to design a circuit but a lot of skill to simplify it. If the transistor is open, both LED’s will flash and if the transistor is shorted, neither LED will flash. If a good transistor is connected, it will produce a short across the LED pair when the voltage is in one direction and only one LED will flash. This allows the red and green LEDs to alternately flash when no transistor is connected to the tester. The other end of the circuit is connected to a voltage divider with the mid-point at approx 4.5v. Output pin 3 drives the circuit with a positive then zero voltage.
