well I am hoping some of my observations may be found useful to those that view. Something I did not know before was the effect of the excessive load on the HOT on the grid bias voltage, I still need to go back and see where it is now, that is if its closer to the -60 it should be now. It may be that the kind of HV regulation that the Philco uses could also be the reason, as it uses a feedback type regulation from a winding on the fly. Since the HV was low (due to the short in the focus coil) then maybe the feedback regulator was just trying to increase the drive to the HOT.
