Hello Jim,
Good to see you here.
At this time I do not recall having seen any Philco literature which adequately explains the "E" suffix tubes.
About all I can say at this time is that, with my extensive collection of Tropic sets which were all designed mostly for "E" tubes, that the standard American tubes (without the "E") serve very well as substitutes.
The 233G/AG and the 263E were designed for export. The UK Vintage Radio Service Data DVD lists a Philco 233 and 263 (which use the tubes you listed, respectively), so these sets were likely intended for export to Great Britain/Europe?
