KPA3 mounting screw

w4sec
Good evening,
While installing the KPA module in my freshly built K3, I noticed the inside tooth washer on one of the mounting screws fastening the PA module to the screen comes perilously close to a trace. It is the screw closest to a board mounted trimmer, and the trace comes from a to-220 device. Is there something I overlooked, or is this a non issue? I didn't see anything on a basic search of the archives
Thanks,
Pete

Re: KPA3 mounting screw

Hi Pete,
That is version "C" KPA3.  I commented on that and sent pictures to the
support team a few weeks back.

Yes either they need to go back to the other design or just use an split
washer instead of the inside tooth washer.

I choose to keep the inside tooth washers and just push it work all it was
worth with my finger nail.  I got it stuck the first time and had to loosen
the screw to free myself.  :-)

The old PA didn't have this problem as the trace was move closer to the edge
of the board.
