[Elecraft] K2 glitch finally found!

[Don Wilhelm]

John,
Yes, 1 megohm of resistance to ground for the negative side of Ctrl Bd C13
is a problem, and yes it should be connected to ground.  If you have damaged
the through-plated hole during your removal techniques, you should connect
the lead to ground somewhere on the back of the Control Board - adding a
wire to the center leg of the 8 volt regulator would be a good way to do
it - because soldering the capacitor on the component side of the board
would be most difficult - that capacitor will be responding to lower
frequency noise rather than HF, so a moderate length added wire should work
just fine.
