It's a standard Elecraft replacement kit for early KFL1-4s, Tim.
See: http://www.elecraft.com/Apps/KFL1_4_Temp_range.htm
There are two available fixes. I replaced the trimmers (Method 2)
because several were very pressure sensitive in aligment and I am in a
very stable thermal environment (SoCalif, one mile from the ocean). And
my 20 m output had dropped dramatically in a 4-5 day period. So I
figured it was time to bite the bullet.
Later KFL1-4s had the newer trimmers, I believe. But I think I got the
first one shipped, or close to it.
I just finished and did the alignment and it feels much more stable.
