Mystery tube

[Heinz und Hannelore Breuer]

Hi,

the UX-245 is a 45. It is an expensive tube (about $80) and quite sought
after. Don't waste it as a lamp.

The only 283A I found is made by Western Electric and is a receiving
tetrode, variable-µ variant of the 259A (Tube Lore by Ludwell Sibley).

It's a triode power amp, good for 2 watts output, and was used as an audio output tube in many radios of the 20s and early 30s.  I can't find the 283 anywhere either, but I'd be willing to bet it's an 83 rectifier, which should also be in your old manuals.

Needed to replace a tube, so went out to my storage barn and found an old box of tubes I hadn't seen in years. They were old tubes that my dad had kept when he was doing TV and radio repair back in the early 1950's. Sure I found some familiar numbers, but then these:

I can't find them in my 1973 RCA tube manual, any substitution manual, Antique Electronic Supply catalogs, nowhere. I'm guessing they gotta be 1920's era. Any ideas, guys (they sure look neat; maybe I'll make a little lamp out of one)?!
