Just to nit pick. It's voltage across the coil and current through the coil. Anyway. you definitely do not want to burn out that focus coil. If B+ in the set is close to what the service info specifies, I'd look elsewhere for a solution.

For instance, the entire focus coil/yoke assembly can move back and forth on the chassis. There are two large screws down at the base that hold it to the chassis and there are slots in the support. It was designed so that you can loosen those crews and move it around. It might not be in the "sweet spot" for this particular CRT.
