Note they also have ferrite rods at the bottom of the referenced page. 
Good for filament chokes.  Note also that I have refrained from making 
any vibrator jokes (hi hi).

I recon theyre still making some new sockets for them too. Now if anyone would like to do a small mobile tube project, this would be a way to go like back in the 40's. They'll also go right in place on the old ones for repairs. I seen they're still around and thought of a small single sweep tube amp or something using a audio output type just playing around. Heck, they're making 6146B's yet at the cheap, about 16-17 bux a piece. Now they wont hold much current, I think maybe 10 amps max so about 120 watts would be pusing one. But, if your looking for a small project to just pass the time and want to work with some smaller tubes, that would be an idea. One could use the vibrator to switch several heavy transistors on and off using a small driver transformer between it and the transistors. This would get you out of having to
