Jones plugs, or similar sorts of plugs

[ Video connector with pins like this : o o o o o o o o ] s/had/have/ in my case :-). Getting replacement heads is decidedly non-trivial, but you can modify the head beam to take Betamax head tips (take them off a Betamax head disk, although where you find those now is another matter). As a totakl OT aside, the portable reel-to-reel Sony VTR I have (which doesn't have one of these connecotrs...) has a nesty design flaw. The head beam mounts on a disk on the main motor sindle, the heads rotate in slot between the upper and lower drums (which are fixed). The problem is that the nut holding that disk to the motor spindle is a normal right-hand thead, with the result the nut can work loose in normal operation, When this happens, the disk wobbles all over the place, the head tips hit the edge of the upper drum and break off. Had they used a left-hand thread, I would have not had to rebuild said head beam. Much as the Microribbon connecotrs are called 'Amphenol plugs' in some books,. I guess. To make this marginally more on topic. I have an NEC RGB monitor that used to have such a connector on the back. Years ago I modified it to take RGBI (CGA) video and replaced the connector with a DE9. I probably still have the 8 pin connecotr I removed, just don't expect me to find it any time soon. -tony
