[Elecraft] K2 question

[Don Wilhelm]

Dan,

Safely, yes.  With certainty, maybe.  Just test them with an ohmmeter as 
you would for any NPN transistor - base to collector resistance, base to 
emitter resistance - some resistance with the probes in one direction 
and no conduction in the other direction..  You may find the resistances 
lower than with them out of circuit, but it should give you some idea 
about their health.  If they show zero ohms in both directions, they are 
for sure bad.
