Phil,

I forgot to reply to your earlier post about the downloaded schematic giving 
5U4G and 5Y3GT as the rectifiers.  There were three common military Super Pro 
power supply models, RA-74, RA-84 and RA-94.  As a group, they differ 
functionally only in the input AC voltage ranges.  However, there were up to four 
versions (revisions) of each, the later of which used 5U4G and 5Y3GT instead of 
the earlier 5Z3 and 80.  So you just got the wrong schematic out of some 9 
possibilities.  Seems like there was also a 25 Hz model as well but if so, I can't 
recall its nomenclature.
