I did it with an HP-250, but that was for a non-functional system (i.e. it 
needed to look as nice as possible, but increased implosion risk was not a 
factor) - hence there's currently just an air gap between CRT and faceplate on 
that particular machine. For that tiny screen, I got enough juice (just) from 
a plain old PC power supply to cut through the failed sealant.

(One day that machine almost certainly will get restored to working order, but 
not in the near future I suspect)

Personally I've used a lot of 70s and later machines and never known a tube 
implode - I think for my own use I'd be tempted not to screw around with 
replacing the sealant (subject to next owner knowing what they were getting, 
of course). I wouldn't want to risk it for anything "public" though.
