Even if you discharge the second anode by the book the crt can hold some of the charge and bite you while you are holding it! OOPS! BANG!

The chassis is considered ground.
I'd discharge it several times, holding screwdriver there several seconds each time.

I've discharged the crt several times, only to have it still bite me a few minutes later. It's not a bad bite, just like a bad static snap if you rubbed your feet on the carpet too long. The worst part about getting shocked is having your hands fly back in response, hurting yourself on whatever you catch them on, or if you're carrying the crt and it snaps at you, causing your to drop the thing.

Typically for restorations, we leave the crt in the cabinet, and pull the chassis out for recapping.

Man, there is cheap, and then there is the uninsulated plate cap on that horizontal output tube! I would be quick to change that if it was my TV, and I intended to be spending much time poking around in there. Is that common on 50s sets? If the 807s on my RCA audio amplifiers were similarly equipped, I am sure I would have electrocuted myself several times by now.

That kind of cap (more of a clip, I guess) is not uncommon in my 1940s TVs, but in those the horizontal output tube is located inside the HV cage, where you have to work a little harder to shock yourself.
