I believe Wayne stated the caps on the main board that require
replacement are 0403 sized sm "chips".
If you have never done any sm work you will find them very difficult
to handle. I have built some boards that use that size and had to
use a magnifier to be able to see well enough to place them. You
need a very fine chisel-point solder iron and small jeweler's
tweezers to handle them. Also very small diameter solder.
I would recommend you find a nearby ham that does this kind of work
or maybe a local two-way radio shop that does component level repair
(though those are becoming rare). In the end it may be better to
send the radio into Elecraft and have all the work done by
them. Ham's in the lower-48 of the US this it not that bad. For
oversea's hams shipping and customs becomes a real hassle/expense.
I will make my own mods but I regularly build sm equipment and have
the necessary equipment. Saying that, 0403 are still very difficult
for hand replacement.

the kits I build use 0805 & 1206 chips.

I think I understand all this now.
One other question, please. Will it be possible to just send in the KBPF3
from my K3 to be modified by Elecraft? not the whole K3?
I think I can handle installing the one cap on the RF board but never done
surface mounts.
Thank you 73
