I was surprised by the number of techs who had a B&K 1077 analyst. I
have had a 1077B for years. I also have a B&K 970 (Radio Analyst). Gee
maybe they are worth something.

Roy,
By golly, I think I got it!
I uploaded this file to tech assist: 931A (PMT).pdf (PMT=3D Photo
Multiplier Tube)
Take a look at it and see if it matches.

I had forgotten about my B&K 1077 which had not been used for many years
until I read the post on it, gee that was a long time ago, how time
flies!

I used one of those B&K 1077s back in 1970. I kind of remember it having
several slides you could insert to get test patterns. Don't remember
much more though. Didn't use it but a couple times.

What sort of analyzer test was that used for? I used to use
photomultiplier tubes in nuclear radiation monitors. The radiation would
cause flashes of light when captured in a transparent crystal material.
The photons would cause electrons to be emitted from the cathode in the
tube. The electrons would be accellerated to an anode. When they struck
the anode a shower of electrons would be emitted. These would be
accellerated to the next anode which was at a higher voltage,
=A0=A0=A0=A0and etc.. It took 800 to 1200 volts to make the tube work.
The various
anodes and the cathode were connected to taps on a voltage divider. The
gain of the tube was adjusted by adjusting the high voltage. The current
from the last anode would go to a milliampmeter or to a pulse amplitude
analyzer. They are still used for this purpose as they are more
sensitive than solid state devices. The Harshaw Chemical Co. of
Cleveland Ohio used to make them and kept large numbers of them on
burn-in. The ones that exhibited good stability at high gain over a long
period of time brought very high prices.

They call it a photo-multiplier tube it picks up a flying dot of=3D
light from the crt which produces an output signal that is proportional
to the amount of light which strikes it.That number=3D
=A0=A0=A0=A0that
I posted yesterday isn't the actual number its B&K's part=3D number,I
have the diagram of the tube if you need it.It also has no=3D heater.

Hi all, Thanks for all the responces and here is all the info=3D I=3D3D
can
supply.
Tube number is in a Sylvania box with a number os 13-27681-4 Size is
like a 6sn7
Bakelite base with a key
Has 11 pins
made in 1968
The words "red"" blue" are stamped on the base There is a visable grid
on one side of the tube. Thats all I can offer in info. Thanks in
