FWIW early on I did all the basic things, including I polished all the pins on all of the Loctal tubes.  I've also checked all of the small components, to make sure I have them wired correctly, no cold solder joints, they have not drifted in value somehow or to insure I was not sold a bad part.  All of the parts I used in this radio are new, modern equivalents.
Rod I know nothing about the proximity of the coils.  They are mounted as they were from the factory.  One is mounted on one side of the, "coil" shelf and the other on the other side.  I'd have to Frankin something to get them closer.
But your comment got me thinking.  I posted a link to this oscillator coil earlier in my comments but here is the schematic for it.
I have tried it in various configurations in place of either or coil 28 primary, and 26.  But I have never ran them both through the coil simultaneously.  When I've got time again I'm going to try that.  You can't get the two coils any closer together than that.
FWIW the old man that has white hair and the long beard told me that I would never encounter a more difficult circuit to service or diagnose than the oscillator circuit in any of the "40s" Philco radios.  I smiled to myself when he said that, I am now grinning out of the other side of my mouth.  

Thanks again for the help.
