I'm sure you've received enough input now to know that any attempt to
salvage such is extremely ill-advised.  It's possible to damage the RF board
just removing two-lead components.  The same thing applies to those resistor
packs, though fortunately for the K1, all resistor packs used may be installed
in any direction, regardless of directions in the manual.

There are better reasons, such as space availability, interference with 
other components around and above the IC, additional lead length and
capacitive effects in RF circuits, and a few others I'm sure.

What has been left UNaddressed is the use of sockets where not specified
on *Elecraft* gear.  It should be sufficient to say that Elecraft officially
*strongly* discourages such, and "voids warranty" and other repair services
when such "enhancements" have been performed by the builder.  Contact 
Wayne for a more accurate statement.  He has posted it to this list on 
several occasions over the past ten years as such "improvements" have 
been suggested.
