Just opened up one of my Predicta's and found this tube. It tests like new. My question is, is this a original tube or a rebuilt tube? :scratch2:

Might be an in-warranty replacement...Many original predicta tubes got weak and changed in warranty.

That's a typical rebuild sticker, notifying you that the tube is made of all new materials except for the envelope (i.e., the glass bulb), which is re-used.

I would expect a factory-rebuilt tube to work as well as a brand-new one.

Yea I need to learn to read the whole label, I saw that after I made this post. So this is a factory-rebuilt tube by Philco in 1962? The way it tests I dont think it got much use after it was replaced.
