I believe there was a msg re this before.  They have improved the 
matching over the years.  So it depends on your S/N how much improvement 
you will get.  There may be something on this under tech notes or 
builder's resources at the website.

FWIW -- this morning I changed all 14 IF xtals (main board and SSB) in 
K2 S/N #380 and it took about two hours.  Since I am now doing the BFO 
and PLL thermistor stuff, I have yet to do a careful realignment.
