[Elecraft] Blown finals

[artus]

Folks, 

I have a K2 that's a couple years old.  A friend and I were working with it
a couple weeks ago and switched an antenna connection -- the K2 went blank.
After a bit of trancing it was apparent that one of the finals went.  It was
not in transmit.  Pulling the bad final resulted in the K2 coming back to
life.  We ordered the final replacement kit and my friend installed the kit
-- triple checked his installation and wrote: "Got everything back together,
checked to make sure the cathodes weren't shorted to ground. Attached the
heat sink. Double checked topside to see if the cathodes were shorted. 
Triple checked. Attached the top cover.  Set PS voltage limit to 10v and
current limit to 1 amp. Dummy load. Punched the on button and voltage
immediately dropped below 1 volt. No smoke, no noise. Cathodes are shorted
to ground. I assume the finals are blown."  I'll get another final kit on
its way -- but need to find the issue before installing.  What is the best
approach?  I haven't written Elecraft, yet.

73,
Jack (W0FNQ)Folks,
