So far as I can make out from the Trader sheet, A to D aren't measuring points for the primary, they're the winding sections, the resistance figure given will be for the total of all those sections, in other words the resistance between the two anode connections for V2 & V3, which I think are the uppermost and lowermost tags of the tags on the right hand side of the output transformer as viewed in the photo you posted.
