After using Google images to track down pictures of 2000 ohm
headphones, I am satisfied that those are what I have. (Eight sets, in
fact.) Found out the one tube is a 6BJ6, not a 6BU6, but it does still
seem usable. Going to ask if I can make some trades with tubesandmore,
so I can find a good home for some of the headphones and possibly get
the tube sockets and transformers I need for my project.

Thanks again to everyone who has helped. Time for me to go do some
math. (Ugh!)

You can just measure the resistance of the phones with an ohm meter.
The result will be close enough to the impedance (I think in the era
they were made they didn't even measure impedance, just the resistance).


Also, I have a lot's used 12au7's. If you need a few you can have some
for the cost of postage.
