Tubular Gearhead

I think I already know the answer to this one, and I am probably out of luck, but I wanted to just throw this out there and see if anyone else has any ideas.
After doing a complete rebuild of a G07 chassis, I figured I would take out the heavily burt tube (Crystal Castles burn), and put in one from a donor TV. As luck would have it, I found a 19" TV with a yoke impedance of 53 ohms and 2.3 ohms- and amazingly enough, the yoke conector was almost the same as the funky one on a G07 (but only four pin, so I had to break it apart). The swap went very well and the tube is bright and perfectly converged, however, I have the focus knob turned all the way to the right and it is just not enough- it is still blurry.
From the schematic, it looks like there is no easy way to increase the focus voltage other than adding on a satelite transformer or something.
So I guess this "perfect" donor tube maybe is not so perfect after all...
Any ideas?
