Jeff,
I've been using, for several years, a scheme similar to the KT88 post you refer. Mine uses 1 ohm resistors for measuring the individual currents and a low ohm pot for a small amount of balancing potential. I think it works great and sounds even better. If you can live with the class A power limitations that are imposed by this scheme then I think you'll like it. I do have several sets of output tubes and I check the tubes periodically to make sure they are matched fairly well. My tubes are pentodes wired for triode operation.
Best,
John
