Christian do you know the gauge of the wire you used ? And the current?

Maybe I should try that approach again!

I don't think so because since the 60s, practically all CRTs have a so-called "integral implosion protection" (thick glass on the front and metal band around the edge). I think it is just an anti-glare filter glass. OTOH American CRTs may be completely different in this aspect compared to European ones.
