Ahh ... very good point, Bob! I forgot that.
I assume crystals can still be had from somewhere, though. I wonder if
Elecraft kept their old stock of them.
I'm copying the list on your reply since it was someone else who needed
a new board, not me.

Dave - To change bands with the K1 boards you also need to change the
crystal.
Good luck,

Unless I am mistaken (entirely possible), all of the K1 band filter

there are several unused two band K1 filter boards out there ... the
result of owners upgrading to the four band module. For example, I
have an extra 40m/20m board left over from when I upgraded my K1, but
I plan to hang on to mine.
If you can find somebody willing to give theirs up, it shouldn't be
too difficult to find the coil winding instructions for the bands
you're interested in. There was even a guy who used to wind the
coils for a small fee, and if he's still around he probably still has
the materials for them.
After all, you don't need a run of boards ... you just need one module.
