I cant seem to find the getters on the 21ax. I know they are normally located in a slot on the neck near the end of the gun assembly, but I cant seem to find it. I do see what looks like silver getter material in the base though near the heaters of the guns. Were the getters ever placed inside the base of the tube rather than on the end of the gun?

The 21AXP22A in my 21CT55 looks the same. There is a picture of it in post #81 of the thread:

Mine has a date code of 5704, about 8 weeks after your date code. It also tested good and makes a nice picture. My avatar is a picture from that set. I say don't worry about the CRT until you get the set operating well enough to get a raster. Nice save!

A couple of questions - When you had the tester on it and got those unusually 'good' high readings, were the heaters glowing a nice healthy orange?

If not, was the neck around the gun area getting really, really hot really fast?

Seemed like the typical orange glow. Got really hot after about 10 mins. Hope it's not gassy?

That's good. It's under vacuum. (If a jug has gone to air, the heaters won't glow, but the neck gets sizzling hot in half a minute due to conduction.)

That would be normal.

Awesome! It should display a beautiful picture then.

I do intend to document almost everything I do while I restore this set both cosmetically and electrically. I am doing this to use it a reference and as a step by step series of the restoration of this set due to how rare it is. Next I decided to get the latex paint specks off of the tuning knob. It was a lot harder to remove the paint on the knob than it was on the cabinet due to the risk of harming the fragile plastic. I soaked the affected areas in olive oil to loosen up the paint and then used a pencil eraser to remove as much as I could. As you can see, I wasn't able to get all of it off, but it looks a whole lot better than it did.
