Ron,
  I also have a model 39 in a similar state as yours . Mine went back on the shelf while waiting for a tapped volume control to arrive and I have not gotten back to it yet. The filter caps were replaced as well. I believe there are some misswiring issues as well due to the incorrect control and the filters so I will really appreciate your under chassis pictures. They will surely help me sort things out.I agree that the model 39 schematic is difficult to follow.
  It would be real nice to see a bottom view of an unmolested example.
                                           Thanks for sharing.
