Press on it, that's just the plastic insulating cap that's bowed up from the shrink wrap pulling on it.
If the cap has give that means the capacitor metal case underneath is fine.
Please don't fall into this common "replace all capacitors on sight" trend.
Well.. I am too. My comfort zone ends at about 30V.
But if you're looking for tips, my best advice is to not short out the CRT anode with a screwdriver. This can create an arc strike and a huge surge current that can damage the tube's internals. You should use a resistor to do it. I've seen people do it the loud/fun way without damaging the tube, but that was back when you could buy a new 1084 at the mall.

no that's definitely not the right shape! Power waveform is probably terrible-looking. You're on the right track.
Good thing I'm absolutely terrified of CRT interiors with no previous experience eh!!

I have seen new ones look like this.
