philco 620,,,#32-1647 if transformer
#8

I may be wrong on the If transformer crapping out,,,the schematic says 20 ohms on both side of this transformer,now,,do the adjustment screws for alinement change the ohms "total "on these coils ??,,,IF transformer # 37 --my reading is 390 ohms on the 78 tube side ,,,with the tube out of the socket,,,,and 385 ohms on the 75 tube side ,,with the tube out of the socket,,,Now,,I have never went to school for any of this,,,and have learned a lot from playing with this,,,JUST a Pipefitter reading schematics,,,has that,,,,Now on the 1st Det. and IF transformer #32 ,,reads out at 11.2 ohms on the 6A7 tube side with tube out of socket ,,,and on the 78 tube side it reads out at 12.2 ohms,,with tube out of socket,,this all started with no plate voltage to the 75 tube,,I had recapped and new resister thru out,,,thank you ,,for putting up with me,,,Kenjr
