Hopefully somebody on this reflector knows of a source of the old (3/8" I think) 3 circuit phone plugs. Not the current production 1/4" jobs. I have a piece of gear with an old 3 circuit jack, like the one used on the T-38 mike, but I can't find a plug in any of the catalogs I have. I hate to modify the equipment, but it look like it's coming to that!
