[Elecraft] KPA500 Assembly Question

[Ron D'Eau Claire]

You should have gotten an errata sheet showing that you need to 1/4" screws
there. The screws were to be packaged in a separate envelope. If they are
not in there, call Elecraft or drop an e-mail to K3support at Elecraft dot
com.

Subject: [Elecraft] KPA500 Assembly Question

I Just started assembling my KPA500 serial number 0585 this evening. All was
going OK until I got to the point where I mount the Z-bracket to the PA/LPF
heat sink. The book sez to use 4-40 5/16" black flat head screws. Using this
size screw does NOT pull the Z-bracket tight against the heat sink. I've
measured these screws three times and I am certain I'm using 5/16" screws.
If I use a 3/16" screw, it works fine. Also, I have verified that I've
positioned the PA/LPF properly. So, is the documentation wrong, or is this
Z-bracket supposed to be wobbly and not tight against the heat sink?

Thanks, Jim / W6JHB
