[Elecraft] 2.5 kHz Mod for the KSB2 (link) - Mouser Part #'s

[Harry Yingst]

Take A Look at:

http://home.pacbell.net/johngreb/modifications_to_the_ksb2.pdf

If you have a newer K2 (3000+) and KSB2 then you should only need to
change out the caps on page 4 (that is all I had to do) since it
appears that Elecraft has already incorporated the 2nd filter flatness
mod.

The mod involves removing twelve caps on the SSB board and installing
ten new ones (Very simple mod).

If you haven't built up your KSB2 then you should be able to just sub
these parts in as you build it.

The Mouser #'s for the caps I used (5% NPO) are:

 39 pF,  581-SR151A390J, 2 Required
 27 pF,  581-SR151A270J, 2 Required
 33 pF,  581-S5151A330J, 4 Required
150 pF,  581-S5151A151J, 2 Required

(The shipping cost more then the caps, so if possible try to go in with
a buddy to split the shipping cost)

I just did this mod tonight and what a difference it made.

(you will need to re adjust your filters when your done).
