Nice work.
I kinda wonder if Philco over drove the flyback in these...My set I've found I need to run a weak B+ rectifier for the rail that feeds the flyback to get boost down about 50-75V below the spec Sam's quotes...If I don't the cathode current is something like 250mA when supposedly the output tube is only good to 170mA. At the lower B+ voltage cathode current goes down to under max spec, HV is still more than sufficient as is width...and everything else seems to work fine.
