Stubborn yoke removal

[bandersen]

I'm trying to pull the 10BP4 out of an Admiral 20X1 chassis and I can't get the yoke past the CRT base The ion trap and focus coil were easy, but I swear the yoke must have shrunk with age!

It's tight but does just slide over the glass neck. I tried putting a little tape over the base thinking it was getting hung up on the plastic lip of the socket, but that didn't help.

If I can't get it off, I'll just work around it. I've no desired to force it and break something! I was really hoping to try out my 5AXP4 for the 1st time though.

Any suggestions?
