[Elecraft] K2: High SWR On Dummy Load

[Ron D'Eau Claire]

Wayne has assured me that torn pads are no problem as long as pieces are not
pulled off and lost, and I have been through that many times with no
deleterious effects on my KPA100!

Ariel.

While it is sometimes possible to clip the leads on the top of the board and
use the remaining leads to mount new diodes, I suggest that "is cheating".
I always remove the board from the heatsink and de-solder the diodes from
below.
Usually, the thermal pads will stay in place and can be re-used unless they
become torn.

desolder and replace those?  It is tight against the back panel and a
toroid.  I do not want to risk damaging the nearby toroid - so I think I
will remove the the standoffs and remove the PCB from the heat sink and
desolder it from the back side (non component) side.   Is this what you
would do?
