Some folk use a hot air gun to melt the solder off the board and then they tap the board and the components just drop out. Be sure to wear safety gloves if you try this!

I usually put on safety goggles and gloves, then drill a small 1mm hole in the centre of the copper anode cap and quickly attach a vacuum hose with blutak (CRTs make good one shot pumps for low vacuum work) someone also suggested this approach for evacuating a fusor chamber if you don't have access to a proper pump.
However for a more effective pump I'd use some prepared 59c alloy to temporarily seal the hole you just made in the tube, then evacuate the chamber and hose with a fridge compressor in reverse. Heat up the alloy with a small induction heater and the chamber should then shortly be at some fraction of a Torr.

Another amusing hack is to salvage the scan coils and use them to drive small fluorescent tubes via induction.
