[Elecraft] Some KPA500 Assembly Questions

[Ed G]

Hi Folks,
     A couple KPA500 assembly hang-ups I have run into so far. KPA500 is S/N
550.  I am experiencing the problem where PA heatsink holes are not deep
enough, so the 5/16 screw length called for (to mount the Z bracket) bottoms
out and the bracket remains loose.  I see in the archives where some use
3/16 length, so I'll do that.
     The other problem I ran into was with the 40 pin I/O cable.  Mine was
not keyed properly to fit the board connector.  One of the ribbon cable
connector pins is blocked off so that the connector cannot be mated in
either direction.  I am proceeding by using a spare hard drive cable I had,
but it has an extra connector along the length of the cable; I'm assuming
this won't cause me any trouble farther along in the amp assembly.
