New Green Tube + Ball Point Pen Spring = TV!
Submitted by: Les Brown, July 11, 2010

A green tube went bad in one of the Norelco cameras. Those cost about three grand apiece in those days; the most expensive of the three tubes per camera. "Bob" (who shall remain last-nameless) undertook to change it with a nice new one. The tube fit perfectly but the base was a little off center and he drove it on with the heel of his hand. That is, most of it. One pin on the tube broke clean off leaving just a tiny stub of tungsten; a metal on which you just can't solder.

We came up with a ball-point pen with the spring-loaded refill (pushbutton on the top of the pen). Filed both ends for good clean contact, put it in the hole in the tube socket corresponding to where the broken pin would fit, squeezed it all together and fired it up....hoping.

Yup. It worked. It was probably several years before the tube needed replacement again and anybody might have had any chance to find what we had done. By then I had left for California to work for Grass Valley (that made the master control and studio switchers) and "Bob" had left to work in Boston.
