	I've done it, it's pretty easy. 

	1/ As per previous suggestion, best is to look for a local jobber
	   for the tube.

	2/ Wierd trick to do convergence without a pattern generator. Do
	   it on Saturday morning. (Why you ask? Because cartoons, especially
	   the cheaper ones with less motion are ideal for checking convergence.)

	3/ Only kicker is to be very careful when disconnecting the HV anode
	   lead.
