2" neck glass for round color CRT's wanted

Yes Tom. I am turning over everything that John Folsom and I had accomplished to John Yurkon and Nick Williams. I would not expect anything to happen in the short term, but with John Folsom having passed on, and my health in decline, passing the baton on to John and Nick is the logical thing to do.

One of the primary pieces of material for rebuilding 15GP22 and 21" round color tubes is 2" soda lime NECK GLASS. We have searched world wide and nobody is making soda lime glass tubing in 2" diameter. All they make now is 2" borosilicate and due to the difference in the coefficient of expansion, borosilicate is incompatible with soda lime glass. So unless we can find some NOS lengths of 2" soda lime glass, we will need to salvage 2" neck glass from dead tubes that are headed for the dump.

I also discovered that dead 7JP4 tubes are also suitable donors for 2" neck glass.

Each tube to be rebuilt, requires about 3 to 4 inches of 2 inch neck glass to extend the neck on the tube, in order to install a new gun assembly.

If you are going to convention we can talk more about all of this at convention if you like. There is still a long long way to go, but every journey starts with the first step and a will to persevere.
