I recall these in Military Aircraft of the 50's --- I believe ARC-27 -- a
UHF Transceiver by Collins Radio

The ARC-1 Transceiver used a smaller rounded version 832B -- we called them
door knob tubes -- see google

So would make a VHF/UHF power output stage maybe 10 watts or so

Hi all,

I just found several 829B tubes - believe it or not in my garage - I
must have got them in a box of stuff at a ham fest at one time.
A check on Ebay shows they're pretty much worthless for the sake
of dollars, but they're so COOL! With the two plate caps that are
actually just stiff pins, they look like little Martians.

I put a pair on my office credenza just to look geeky cool. Fresh
out of the box as NOS they look amazing - just like they were made
yesterday. It's a pity they have no value - maybe as a homebrew
project??

So can someone tell me what they would have been used for?
Something tells me they're a VHF power tube.

Any application as a one-tube QRP rig of any sort? Any stories
about using them in the past? I've built a lot of little rigs over the
years, but never knew about the 829

Thanks,

Dave

They were the final in the TX of the AN/ARC-3, too. I never got
mine lit up, as I went into the USAF not long after I got mine --
surplused (or something) from the Civil Air Patrol, way back in
1964.
