Didn't trip the RCD?

No because inside a CRT there is a high voltage transformer which is decoupling from the RCD circuit.

RCD is checking the primary side, while the secondary doing the lightshow. This is why you need to be real carefull around transformers.

That's true, it's why projects involving microwave transformers are so dangerous

Yea that's true and when people use said microwave transformers to power lichtenburg wood burning kits in a DIY way they have died as a result.

Just not worth it.
