[Elecraft] Are matched XTALS needed for new K-2, KSB2

[Brian Wruble]

Hi all:  I have on order, due any day, my second K-2.  I ordered it with the
100watt amp and the SSB board.  In looking at all the mod kits --- which I
needed for my first K-2 (S/N 2528), I see that the matched XTAL sets for the
K-2 and the KSB2 do not carry the notation "supplied will all K-2s..." of
recent vintage.  Do I need to order these separately in order to have the
best possible performance, or are the K-2s and KSB2s now coming with
appropriately matched sets of XTALs?

Tnx de Brian W3BW
