What are the main changes in the schematic between the pre-war 1942 PT-2 transitone and the post-war 46-250 (besides the obvious different 35Z3 tube in the PT-2 and a 35Z5 in the 46-250)? I have a PT-2 I just got and want to have ready to give to a friend when he's in town next Saturday. I'm working off of an original Philco Service Bulletin with the schematic for the 46-250, as I don't have the complete schematic for a PT-2. One thing that puzzles me is that it appears certain capacitors are reversed between the two different models. I can't imagine Philco would've made that many changes to a relatively simple radio when everything else appears identical. Any thoughts from those who have had experience restoring these two different models would be most appreciated.
