tubes age 96
I seem to recall a method where you use a small wire that you hook up to a 12
volt car battery until its glowing good and hot, then quickly wrap it around the
tube where you want the break to occur and dip it quickly into water. The hot
wire heats the tube at the break point and the rapid cooling snaps it cleanly off.
Anybody remember/try this technique?

I was wondering when someone would propose this. It works very well for
bottles, jars, etc. -- as long as they aren't made of zero-TC glass or quartz. A
length of Nichrome toaster element would work very well, as long as it doesn't
turn out to be fragile.

I seem to remember being taught to wrap a piece of string around the object,
soak it with lighter fluid, ignite it and let it burn out. Then the quick dip into cold
water. Just another twist on the same routine.

I have had mixed luck with a small file. I etch a line around the tube and then
tap the tube with a screwdriver handle. Most of the time it will break clean. John

Subject: [R-390] 26Z5 vs 26Z5W
Is a 26Z5 and a 26Z5W the same animal? I found a source for 26Z5 (no other
information) for supposedly $7.00 each. My tube references don't seem to
adress this beastie.
