Hi Steve.. On the Webster/Hammonds, i don't use the center tap.. i cap it off... I use the two outer leads,(full primary winding) one of which is blue and the other usually white.. i connect the Blue lead to B+ and the white lead to the plate..
i have found that some of these OPT's have a DC resistance of 120 ohms, others have 60 ohms.. i use the full primary in both cases and find that they seem to work fine...
