In the early days the tube manufacturers inverted the half-finished tubes and dribbled really high quality sound into them before they were sealed up. It was the best sound ever contained in a tube. That e-bay price is cheap, 'cos tubes that good are worth millions.

No wonder they're all gassy!

They are output transformers, for military tube radios. They are pretty narrow-band to use as interstage transformers for audio.
Actually that is close to what I remember us using in the ARC161 1KW HF transmitter back around 1975 when I was Intermediate Repair at NAS JAX. It was an inerstage transformer between the AN-ARC150 transmitter and the modulator output for the AN-ARC161 Linear amp (400W-1KW).
Although it has been a few years and it WAS the 70s, so I could be mistaken....
Some people must think they are worth the money he has 10 bids on one 300a $1500.00 auction #300338776081 .
It must be me but I don't think my ears could tell if the sound was through a 300a or a
6L6 given other equal components. (Hmmmm lets see the graphite plates give a SMOOTHER sound becouse its a good dry lubricant) or maybe just helps slip the money from your wallet faster !!

Tubes before boobs
You mean like this?
An externally hosted image should be here but it was not working when we last tested it.
Hmmmm those 4-400a's would make an interesting pp amp, you would just have to wind your own transformers, but i bet it would be LOUD !!!!!! EARSCHPLITENLOUDENBOOMER!
Albeit a little wimpy compared to a GM-100

I'll give the guy the benefit of the doubt because he could have thought he was specifying Hong Kong dollars. There is no excuse for things like this which are fairly more common on eBay:
