[Elecraft] New Crystals

I have received - very promptly, I might add - the set of 14 new matched
crystals to replace the CW and SSB filters in my K2.

I intend to connect case ground wires to both sides of the CW filter
crystals at the very bottom of each side *before* installing them. So each
crystal will go in with two signal leads and two ground leads already in
place.

Similarly, I intend to attach case ground wires to the SSB crystals very
low on the cans and to route them to the existing ground through-holes with
the shortest lead lengths. Thus these crystals will have three wires on
each prior to installation.

I think that this procedure will not only allow for much lower inductance
case ground connections but will greatly facilitate installing the crystals
and their case grounds.
as well as allowing a better and quicker soldering job on the cases.

Any comments or ideas?
