[Elecraft] K2 & P3

[John Chance-Read]

Can anyone help me with the following :-
1.  Can the new Elecraft Pan Adaptor be used with the K2 ?
2.  My Elecraft 7040 sig gen seems to have lost some output - 50uV o/p  only reads S5 on the K2 instead of S9 and indeed also on my Orion and no indication on my Oscilloscope which used to indicate 1/3 of a division on the extended range.
I have probably put a little radiation into it !!.
What component should I first test/replace.
