I'm in the middle of building Musikding's "The Range" kit and have come to soldering the transistor to the circuit. However, i'm not sure which leg of the transistor is the collector, base or emitter. The transistor is a PNP AC 128. Two of the legs are the same length, while one is slightly shorter. There is a small tab that sticks out from the metal casing, and there is a small red mark on the casing next to the small leg. Any ideas as to which leg is which?

Any help will be great!

The leg closest to the tab sticking out is the emitter.

Red dot symbolizes collector.

If in doubt test it with a beat meter and arrange the pins in a way that you get a reasonable hFE reading.
