 GM> Yep. For my money they are SCRs.

 RJT> I don't think so,  but let's see what an ohmmeter has to say about
 RJT> it... 
 RJT> Nope.  Reads like an NPN transistor,  with the pin that's common to
 RJT> the case being the collector,  I'm guessing.

It's time to set up for some DC tests with a power supply and
resistors, and see if they act like NPN transistors.

 RJT> They're pretty dirty,  I need to figure out something I can clean them
 RJT> with that won't affect any numbers that might be on them.

Plain water and a soft brush is the safest, but there are no
guarantees that even that won't remove the numbers.
