[Elecraft] Back in time question

[Doug Hensley]

What test equipment is needed to accurately perform the alignment
and proper tuning of a used K1 or K2 ?  

I'm not looking for minimum recommendations nor NIST-Traceable
recommendations; just what is needed to make sure they are up to
spec or up to speed for the guy who wants to enjoy what they are
capable of doing.  I hope this is not a trick question.

If there is another list or email venue I should be using for this question,
please let me know.  Thanks for reading.

Thank you.
