Yea, when Jim reminded me of those globars, I realized that would be
perfect to slow down the current surge on
my old radio with the 117Z6 rectifier, that lights up like a light bulb
when you first turn it on! That's gotta shorten the life of the tube,
big time!
In my mind's eye, I could see one of those globars, still in the card,
someplace in all my old TV krap that I never threw away. The question is
- can I find it?
So I headed out to my storage area, rumaged around, found my old tube
caddy, and found the globar, still in it's wrapping, just like I saw it
in my mind's eye. Way Kool!

Those things are really pretty cool. I think they are around 100
ohms cold and about 1 ohm hot at up to 3 amps. They are great for the
primary of filament XFMRs for Xmitting tubes. I used to use them all the
time. We kept them in stock for the degaussing circuits in TV repair but I
haven't seen them for a long time.

George: You might search around for some old "Globar" resistors. Install
on the input line and they will absorb some of that inrush resulting in
longer life for the tubes.
I found a card of them (they were in little packets that one pulled off like
the pull tabs you bought at the beer joint) in little bags. They were used
in TV sets and AC/DC radios. Check for a parts store that has been in
business for a long time and find the guy with gray hair and an unsteady
walk. He will know what you are talking about.
