Greetings- I have one in a high level transmitting mixer I built in about
1960. The mixer took about ten watts in on 14 mhz from my HT-32B, mixed it
with the output of a crystal oscillator, drove the grids of the 829B ,and
the output was 144 mhz ssb, enough to drive a 4X-150A amp. The circuit was
designed by Don Stoner, W6TNS, and published in CQ mag., as I recall. The
tube was used in VHF military gear . It has a little brother, the 832A.

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
