Tektronix used this type of tube in some of their later vacuum tube
scopes. Some audio amplifiers also used them. Can help improve tube life
by keeping the plate supply off until the tubes warm up.

They're in their original boxes.
I have no idea what devices used them.
It seems a shame to throw them in a recycle bin.
Does anybody want them?
