[Elecraft] K3S Build Progress: 1st power-on

[Gary]

And if you have one, ask the cat to stay away. Why you ask?

Ha, mine relocated several parts and water boarding, threats, pleading, shaking....didn't do a damn bit of good.

The assembly manual is quite clear when it calls for SS (stainless 
steel) hardware.

RE: surgical rubber gloves - I would advise against that. The purpose of 
the anti-static mats and ESD percautions would be defeated by the use of 
any insulating material between you and the boards you are handling. 
Remember the whole purpose is to keep everything at the same potential. 
Remember the old high school physics experiment of the rubber rod and 
the silk cloth?

The TCXO is probably in a small box protected by conductive foam.
