Zsuttle, I soaked mine overnight YMMV.
I'd go back to Squirrel Boys suggestion.

I actually wasn't that wound up...IIRC I had a spare 21AXP22 then, I knew the tube I had was toast if I did nothing, so I had nothing to loose and everything to gain, I had done a similar thing with a monochrome tube before I knew how to solder at my current level and cracked it with heat so I had a feel for max dwell time on cold glass. I had those wire stubs shiny ready for solder, warmed the glass to improve tolerance to solder temp and besides the actual soldering (which I did with calm sharp focus) I did everything slow and deliberately. I won't say I wasn't a bit tense but I was relatively calm.
