If nobody already posted the info (didn't read all the replies) the tube
used is a type 955, and it's not very rare. I see them all the time and
have one spare for my model 59... -WB2WIK/6

Carl,
The tube is what we called a "gland" (hope I remember well) quite a time
ago we used that "gland" in UHF triode preamplifiers. Probably difficult
to find in a industrial environnement. A special request would have some
results I believe. Quite sure one or an other OLD TIMER still have one
or more sleeping in their old drawers. Unfortunately I forgot the code,
but i stil see it sitting in its 4 or 5 pins socket disposed
horizontaly.
Just a question, whats worth a Boonton grid dip nowadays ? 1976 last
time I used the grid dip in our lab.

Objet : [Amps] boonton 59
I have acquired a boonton 59 dipper. In looking at the innards I am
curious about the oscillator"tube" !! The unit works fine on all bands
, but if that osc. fails, where would anyone ever find a replacement ???
The "tube" has no markings on it and the "megacycle meter " is connected
directly on top of the tube shell.
Can anyone tell me anything about it ??
thanks
carl / kz5ca
