[Elecraft] KPA100 Tightening the finals...

[Ward Willats]

Just finished the KNB2 for my K2 (a birthday present from the in-laws 
-- yea!) and while I was inside the K2 to install it I tightened up 
the screws on the KPA100 finals per Elecraft's recommendation, since 
I've been using the radio for about 6 months now and this was 
probably overdue. They all took a little snugging up, maybe a little 
less than 1/8 turn.

My question is: will they stay tight now for all time? Or do I have 
to check them now and then? What's the theory on the thermal cycling 
here and how it effects these screws?

Just wondering...
