Forget it - I just used Brute Force and the thang came off.

I'm glad you got it off... but you were lucky! I'm guessing you have one of the new non-slip knobs with the o-ring in it; those can grip the shaft pretty tightly. I have one of those knobs and I deliberately installed it incorrectly (with the O-ring just sitting on the shaft rather than inside the knob) as I have not yet had the infamous slipping knob problem and didn't want my knob installed so tightly that it couldn't be easily removed, yet I still have the option of installing the O-ring properly should the need arise.

Anyway, you were lucky -- because brute force pulling on that knob/shaft assembly has been known to result in a broken fill nipple on the display board (see here -- sorry if I brought back some unhappy memories, David...) and that's a pretty expensive repair.
