KPA500 PA/LPF module mounting instruction problem

[kp4md]

While building the KPA500 I found that the ten mounting holes on the PA/LPF
module heatsink were not tapped deeply enough to accommodate the five 4-40
1/4" screws specified on page 22 of the assembly manual, nor the five 4-40
5/16" screws on page 24 of the manual.
I had to use the 4-40 3/16" screws in both cases.  If I had used the screw
lengths as the manual specified, the module would be loose and insecurely
fastened to both the Z-bracket and the right side panel.

So, did you contact Elecraft support to discuss the issue?

Yes, I found this to be the case in one built a few months ago  Reported
to ELECRAFT.

This has been a problem in the past too.  Used shorter screws.

Never got a response.

I have never had an issue with Elecraft response.  Did you call or email? Try calling.  Has always worked for me.
