[Elecraft] Tightening K2/100 PA device screws

[eric norris]

Dear K2 Wizards:
I bought a K2 from a friend's (WA6OCP, SK) estate, and had a 100w lid built into it by Dave, W8FGU) who also gave it a full checkout and realignment.  I've now got well over 10 hours of TX time on it, and according to the manual the PA screws need to be tightened.
My problem is I can't tell from the manual  exactly which screws to remove so I can pry the heat sink up.  I've lost my fine motor control in my hands, so this is going to be a bit more of an adventure than it would've been 10 years ago.  I'd also appreciate advice on which tool I'll need to tighten away (1/4" nut driver?) and just how much to tighten.  I suspect it's the same snugness I used on my own K2/10 back when dirt was new?
With SKN coming up quickly, I'm hoping to put this K2, and the HW-16 given to me by my Elmer, W5NYT (SK) on the air as my tribute to them.  
Thanks for any advice!

73, Eric WD6DBM
