[Elecraft] [K3] jack size

[Ken G Kopp]

I have a large number of "1/8"- plugged patch cords.
None seem to fit the K3's jacks correctly.  I've always
attributed this to the quality of the jacks, not a possible
size mismatch.

The plugs on my several Heil headsets fit so sloppy
that I've sometimes used tape to hold them askew
to maintain contact.

Are there plugs commonly available in the US that -do-
fit properly?

73!
