Guess what...the audio output transformer primary is wide open.  Where can get details on the parts for this 40-165K?  Ohms don't tell the whole story.  I saw some books about philco radios in two volumes.  Will they answer the questions I have about part details?  I want to order the right output transformer.  Although my basic electronics is weak, I have swapped enough boards in digital equipment to know that even a part number suffix can make the difference between working and staying up all night only to find out I needed a C board not and A board.  Thanks for your help.
