I did try it on one tube over the weekend, it SORT of worked, but did not like it, it was unstable, would lose h-sync when power cycled, much more stable with both tubes, comes up with lock each time.

Still don't like how hot the FBT gets, but at this point, there is not much more I can do about it, as it seems to be the way it was made, I will attempt to put some heat sink paste between the FBT and the large copper plate they have there for cooling which I hope will pull the heat away a bit better, there was nothing originally, this plus a massive case fan will hopefully keep it from frying.

The focus coil also gets rather warm, this I'm guessing is normal as they had a 5w 560 ohm resistor and 5w wire wound 2.2k pot in the circuit, both of which fried when the pot failed and shorted to gnd, I could not find a suitable 2.2k pot in the right power range, so I got a 5k 5w wire wound, this should not be a problem as only one end and the center is used, and the 16LP4 uses a bit less focus current than the 16FP4 that was in there, so the extra range won't hurt, 146ma vs 110ma, I still have to clean the rust off the focus coil and fix the disintegrated covers on the yoke.

Overall, I'm impressed with the level of detail I'm seeing in the video on the 8YP4, even though it's not a good match to the set, and it's smearing, it means the IF is pretty good, and so is the video sections.
