an excellent way to gain greater understanding of how to accurately
check transistors.
You can purchase several types of general-purpose replacement
transistors for less than RM 1.00 each from many electronics suppliers.
Get a few NPNs and a couple of PNPs, grab your multimeter, and see for
yourself. With some actual hands-on activity, it wont take you long
to become confident performing a basic transistor test.
If you have a budget you may buy specialized transistor tester where you
clip 3 of the tester wires to the three pins of any transistors. After
analyzing, it will prompt to you which leg is the base, collector and
emitter and also it will tell you if the transistor is good, leaky or
completely shorted.
