Charlie,
I don't have a set of calipers or mikes handy but grabbing a steel
rule and measuring three 3.5mm plugs at random off my bench - they
all look to be 9/64 (0.14"). I do know that I've thrown out all of
the 1/8" plugs I had because they make such bad contact in equipment.
I don't know of any amateur manufacturer that is still using 1/8"
jacks. They can be damaged if one forces a 3.5mm plug into them.

That doesn't answer my question..... Are they REALLY 0.137795 inches
or is 3.5mm just a rounded off way to describe the same physical part
using two different measurement standards?

3.5mm is 0.137795 inches, 1/8 = .125, that's quite a difference in terms
of a good contact.

fight, but I think it's worth knowing. Anybody know for sure? I have
found that a particular "miniature phone" size plug to be very
difficult to insert, so it might be a fact.
Sorta like a .38 cal is actually 0.357" and very close to (wimpy) 9mm.

3.5mm & 1/8" are not quite the same size, so if you've put a 1/8"
plug in a 3.5 mm socket, you might find this problem.
I have no problems with my K3.
