[Elecraft] Time for a new Volume pot?

[Don Wilhelm]

Brent,

Since you asked, the pot replacement is actually rather easy - just take it
one step at a time - first remove the front panel from the K2 (don't forget
the screws from the control panel to the front panel on the inside); then
remove all the knobs and the one screw next ot the VCO encoder to separate
the front panel board from the metal panel.
After that, remove the pot itself in whatever way you remove such
soldering - if you do not have a powered desoldering tool, I suggest that
the easiest way is to destroy the existing pot (no sense in preserving it,
you were going to throw it away anyhow).  With a set of heavy diagonal
cutters, first cut off the 3 pins and then crush the pot body a bit so you
can cut the two mounting ears off - after that, you can easily heat the
stubs left in the board pull them out - clean up with solder wick and put
the new pot on the board - re-assemble after doing the AF Gain pot wiring
mod (if applicable).

And as Ron pointed out - if your K2 serial number is less than 3000
(probably is if you are replacing the pot), make the changes for the AF Gain
pot wiring mod - it will make a difference in the future for longevity of
your new AF gain pot and makes the AF Gain control less 'touchy' and less
noisy.
