depends on plate voltage, plate current, whats the drive?
8950 is just a ruggedized 6LQ6/6JE6. Horizontal output tube (thats from a color TV).

100-150W PEP output per tube is normal with about 900V on the plate. CW "key down" it will do that also but only for a very short while until the tube overheats...

As Steve said, that tube will put out quite a bit of power, but you have to remember that, although it's ruggedized, it's still a sweep tube.
Keep mindful of two things: They are expensive and they are fragile.
Keep the duty cycle (key-down time) short.

Re ZNA...
In reality th 1011 series were terrible radios. They drifted terrible. They were the poor mans Swan Radio. And Swan Radios sucked.
Compared to the new program control radios of today (which only cost less than a thousand dollars) the 1011 any series pretty well much sucks.

I had one once and it didnt drift that bad. After about 30 minutes warm up time it didnt drift that much. It gets me how some people will down something that they know not much about.

I had a 1011 D once. It was awful! It drifted like an untied boat. I sold it and took the money and ran like He&&!! Now i did own a Swan 700 CX and that bugger never drifted after about 25 minutes of warn up time.
