[Elecraft] K3 - modification - some ideas

[d.cutter at ntlworld.com]

I'm not in favour of bringing the mains supply into the box.  My dc power supplies all have isolated outputs, ie neither go to the psu frame/ground, so mains earth is separate from rf earth.  I know it's done on some big t/rx, but I'm not in favour.

Even with a small mains psu, you might have mechanical issues fixing to panels not expected to hold weight, eg leverage against small screws into pcbs.
