[Elecraft] KPA-500 Question

[Don Wilhelm]

Gary,

Try to put a 4-40 screw into the holes.  If it goes through, it is a 1/8 
inch hole (clearance for 4-40 screws), but if it must be threaded in, 
all is well.  A threaded hole for 4-40 will look almost like a 1/8 inch 
hole.
Yes, the holes should be threaded for 4-40.
