[Boatanchors] sweep tubes (was Re: Galaxy V)

[Marvin Match]

I find this discussion of amplifiers built with gobs of sweep tubes 
interesting, especially the idea that it's easy to vaporize the tubes if 
you fail to tune up quickly or improperly.

Personally I've always felt that sweep tubes were being abused when used 
as RF output tubes in a rig or an amplifier . . .

However, I've always been curious about the GE 8950. It was marketed as 
an RF output tube, but as far as I can tell, it's just a sweep tube like 
all the other sweep tubes. The inter-electrode capacitances  are lower 
than some sweeps, but otherwise they smell and taste just like sweep 
tubes to me. Even in the spec sheet, although the description is "linear 
amplifier and RF PO aplications

Just wondering . . . is anyone aware of differences that make the 8950 a 
real transmitting tube, like heavier glass, or thicker plates, or are 
they just sweep tubes with a different marketing campaign?
