Okay guys not too sure how easy this is going to be I have the yolk from the old tube but the purity ring busted is it as easy as finding another 19in CRT to swap it out with assuming I'm using the same yoke but different Purity rings
 
Use the k4900 yoke and use the rings from the new tube. Try to mark the exact spot the rings are in on the new tube, it will get you in the ball park.
