Info/Schematics wanted for V72S (that's the "S" version, not plural)

Like the title says...I have searched the archives but found no valid links to a schematic for the "S" revision.  I understand it has 40dB gain due to a different feedback loop and possibly different xfmr wiring.  There is mention of EMI documents to convert a 72 to a 72S, but I have only found those on ebay  :-\

Nevermind, it seems this unit was downgraded to standard V72 spec.  However the secondary of the input transformer is measuring waaay too high (4.6 meg with R11 removed).  Looking for rewind or replacement.
