Got this one Sunday
I think it is a Latham. It's very unmolested and the picture tube has a date code of 60-22. It looks like the original 21CYP22 as it has the serial numbeer still on it. And it's good and strong! The flyback has what looks like a white outer covering on it and very little wax dripping. The tag has a repair date of 1968. It was originally purchased and lived about three blocks from my house. A friend of mine found it at a hugh garage sale a few miles from here. The circuit boards are nice and brown, not black. Even under the vertical output tube. This critter has a number of bumblebees under it so I'm going to replace anything suspicious before the variac gets started.
One question... how does the front glass come off?
