Philco 144B low volume
#11

I just checked the tube socket pins and traced them back to the socket. Here’s what I found,  pin 3 of the 42 tube goes to pin 1 of the socket, pin 2 of the 42 tube goes to pin 2 and 4 of the speaker socket, pin 1 of the 80 tube goes to pin 2 of the speaker socket. 
I think something’s wrong so I’ve attached a picture of the back of the output transformer. The green wire goes to pin 1 of the speaker socket, the yellow wire (replaces striped wire) goes to pin 2 of the speaker socket, and the white wire goes to pin 4 of the speaker socket. 
Both the white and yellow wires go to the field coil connections.  The green wire only goes to the output xfmr.
