How to Find Substitutes for Discontinued Transistors

As promised in the Fisher RS-2010 video series, here is my attempt at showing how to find substitute transistors when the original is not available. This problem presented itself when we tried to order the components for the STK discrete component modules used in the video. In this video, I go through the process of finding a replacement for the NJW3281 transistor. The same process can be used for other transistors. As you will see, I actually found another source for the original NJW3281, as well as some alternates.
