I have a few transistors(I think) I am trying to identify.
They look like stud mounted SCRs with a 1/4-28 stud but the ohmmeter
says they are NPN transistors. They were in a bag marked "servo amp
transistors" no ledgable markings on the transistors. Any suggestions
as to which type they maybe.

M cubed makes a nifty tester that automatically identifies the leads, type
(NPN etc) DC beta , leakage etc.
