I didn't hear it mentioned (or might have missed it), but was the OP using a digital or analog milliameter to measure HOT current? As digital meters are known to go nuts in applications involving high level pulses and waveforms, I sure as heck would use only an analog meter there. And I would do it at the cathode, not the B+ fuse.
As for another poster's statement, "For me I wouldn't get obsessed with voltages, currents, et cetera. The picture displayed tells just how close you are."
Yeee-ikes! That advice might pass muster with B&W. But with color, it is absolutely critical that the HO cathode current be kept within spec or lower. Even with the later 6JE6 and 6JS6 (in Zeniths) we would strive for no higher than 210ma to give the tube and flyback a reasonable chance of survival. 200ma was ideal if width and regulation were adequate.
