Yes, its very difficult without a print, especially if the radio has been modified. It looks like that transformer at the bottom left in the photo is not original, so who knows if it was wired in correctly. If it was connected to the plate (pin 2) of a 226 tube, it might have been a interstage transformer driving the grid of the 71A, not an output transformer, but then why was the speaker connected to it?
What is the transformer in the upper right? is it connected to the 227 detector plate? What does the grid of the 71A (pin 3) connect to?
