Unfortunately my aged caliper gauge is damaged and not good for
measuring inner diameter. However, it's good to measure outside
diameters. At least one of my Neutrik jacks has got a measured outside
diameter of 6.35 mm, while one of my elCheapo's has got an outside
diameter of 6.3 mm and there's still much clearance, if I connect
the 6.35 mm Neutrik to different sockets. I can't say for sure, but the
inner diameter of a socket might even reach be around 6.9 mm, which
would likely be enough space to join with a 6.5 mm jack. OTOH data
sheets from at least two vendors mention an inner diameter of 6.4 mm,
for the sockets, too small for 6.5 mm jacks. Anyway, I own a lot of
cables with 6.3 mm jacks, that can't be used with a lot of 6.3 mm
sockets or they at least don't ensure a safe connection, especially not
for "mobile" instruments, such as guitars ;).
