Howdy,

I purchased a large lot of tubes for my audio gear, and wound up with
this RCA tube in the box as well. Someone told me to post it here, as
there are ham radio, Hallicrafters etc that used these tubes.
Frankly, I don't even really knows what it is.

AE i selling them for $129. I'm offering mine for $85 (Inlcuding
shipping) in the US.

Please e-mail directly if you are interested. (I have a lot of
online references if requested...I've just never posted to this
individual group before.)
