Hi All - just getting back into restoring radios after a few years away and it feels GREAT.  Last fall I picked up a Philco 15X radio in great shape but of course not working - the fun part.
I have recapped the set and am able to fire it up to silence. 
Checking the voltages per the online schematics I found the P to K voltages on the Push Pull 42's to be about 10VDC and should be 255VDC.
Checking the Output Transformer I am seeing something I have not seen before.  The primary side has 2 leads attached to the plates of the 42's plus a center tap.  I have 295VDC at center tap and nothing out of the top and bottom leads.
Weird thing is I get 7K ohms measuring between top to bottom leads BUT 0.7K ohms CT to each of these.
Is this transformer pooched?  Am I missing something?  Suggestions for replacement?
All other voltages on the set are close - just the P - K on the 42's are way out.
