It is the original 21FB22 manufactured in the 43rd week of 1961. All the tubes except the damper are Zenith and I assume the originals. Availability of 3DG4 in the future kinda worries me.I need to stock up on a few if I can find them.Definitely need to get the old filters outta there.Can't afford a short with those tubes and that transformer which is probably unobtainable.

I also think it's a low hours set due to all the original tubes and the underside of the chassis basically untouched.The chassis is very clean.No rust or corrosion anywhere and only a light coating of dust/cigarette smoke deposits. Wonder how the cabinet got so beat up?Since it's a basic black cabinet it should be fairy easy to fill in the gouges and refinish though.

With all the original tubes in there and apparent light usage kinda makes me wonder if Zenith was hard on damper tubes.I was once given a Zenith 20YC38 chassis Zenith that had sat for years unused because the damper was arcing inside. All the tubes were Zenith and CRT strong.I sold that set when I could sell a console tv for $100 or more.Kinda wish I still had that set.
