Guys -
There is no problem here. The recessed area on the KPA100 heatsink is
actually exactly where it should be with regards to the height of the
other standoff locations around the edge of the heatsink. The recessed
area is will definitely vary from heatsink to heatsink. The reason it
may
Ben,
I just finished building my KPA100 and it is quite happy in the K2 at this
time. I agree with your observation of the milled out hole on the heat sink.
I tried placing a lock washer between the heat sink and standoff (against
Elecraft instructions) which resulted in not having the screws
Ben,
Every KPA100 heatsink is milled in that area to remove part of the raised
platform that the PA transistors mount on and still allow for the standoff.
Just how much below the lower adjacent surface (large lower area) has your
heatsink been milled? In most cases, it is only a tiny bit (1/64 in
Anyone have any insight on this?
