Ya your right, I was refering to the sub mini not the nuvistor for the proximity fuse.

Yea the were made long after WW2 don't know the exact date off hand but I want to say late 50's early 60's.

I remember the RCA "New Vista" (get it) TV set commercials, so they had to be in the 60's.

OK, Google knows all. The New Vista appeared in 1961 with the CTC11 chassis. The 6CW4 that it contained was probably developed in the very late 50's. They are horribly microphonic little critters, and here in Florida they rust!

Thats funny that they are horrible microphonic because everything I read says they were made to not be.


But that doesn't really surprise me though.

Is the question tube "power amplifier" -- you could probably use ONE 6360 dual pentode for a couple of watts. My first 50MHz ham transmitter used this tube.

You won't get much power out of a Nuvistor -- I have a bunch of them around here -- used as VHF preamplifiers and converters.

Y a I know they are power tubes, but they are a tube and they are smaller. This is the only reason I said that.


Do you have any you would want to sell?

I have some in the original GE boxes.

But I'm not parting company with any:

I can't imagine that this type of socket does it any good.
