Mark, are there two separate isolated secondaries, or a single center tapped secondary? If it is center tapped, you can just remove the feedback networks and it should work fine with the step up ratio.
The reason for the original step down transformer was to provide enough current to drive the grids positive in Class AB operation. With the step up transformer you can just run in Class A with a few less watts output and you will never notice the difference.
