[Elecraft] [KPA500] Leftover parts?

[PTA_ABD]

Same deal here a few weeks ago.  K6RB is exactly correct. The purpose of the washers and nut is to provide extra support so that the bottom panel wouldn't suffer any warpage during rough handling. ( There's a plate underneath anyway)  I can assure all that it works fine without them. I have no intention of tearing it apart because it will be sitting on my desk. Not sure what anyone else does with amplifiers in terms of physically handling them.

Surprised that they're still being shipped w/o an included addendum to the assembly manual. Revision wasn't on the website last time I looked either. But a query to Support brought an immediate answer.  I love the Support crew at Elecraft.... can't say enough about them.
