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 ;). -- pacman -Q linux{,-rt{-securityink,-pussytoes,-cornflower,}}|cut -d\ -f2 4.18.12.arch1-1 4.18.7_rt5-1 4.18.5_rt3-1 4.16.18_rt12-1 4.16.18_rt11-1 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
