Yes, the Scott slrm I have has a few of them in the AC line
I think, and that receiver starts up nice.

God help me if I had to replace one of them...

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!
