Someone had published the schematic for a model 90 using PP 45's about three or four months ago, on this site. I am sorry I don't recall who, However I do have the diagram and it does work, because I needed it for my own use. It shows the 4 pin plug as well as the output transformer and field coil wiring. I am willing to make a copy and mail it to you if you wish, or I can take a picture of the sheet and e-mail it to you. Tubesforme (Michael)
