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.

Well the Assembly so far has gone pretty well; other than the odd hardware
dance. This is an area that can be improved dramatically without being
overly complex. There's apparently one set of Stainless hardware and the
rest are zinc. I infer from the assembly that all (or nearly all) hardware
that is on the OUTSIDE or mates to outside screws/bolts is stainless.
Everything internal ONLY is zinc.
My Hints/Tips:
1. Wear surgical/rubber gloves - During assembly I suggest wearing thin
rubber gloves (lowes, home depot..etc.. ). That helps keep oil/fingerprints
off of everything and you get a slight better grip.
2. Use a magnetic parts tray - even for the SS hardware it helps as they
have some slight carbon content.
3. Use a magnetic tipped screwdriver.
4. User gravity to put/keep washers on the screws - don't be afraid to
pick up the assembly you're working on and position it such that gravity
helps keep parts where they need to be. Keep it Simply Simple.
5. Work in a well-lighted area and I'd even suggest a desk/work lamp. I
have plenty of light in my office and the addition of a desk lamp made a
dramatic difference to my work.
6. Don't mix bags - keep hardware from one bag in it's own container.
Don't mix zinc and stainless J
7. Don't be distracted - ask the wife, kids, pets, ..etc.. to leave you be
for a bit. I had to dis-assemble/re-assemble the front panel several times
because my better half wanted to share details of something. Being that she
has the higher priority I listened and inadvertently assembled some parts
incorrectly and caught it on verification.
Well I'm past the resistance and first power-on test. Just need to figure
out if/how they packed the TCXO. I have the KREF3 module but can't locate
the TCXO.. not many parts left, 3 modules, the 100w PA and sheet metal mmmm.
