Installed the Hammond 125D and it works fine.  It has the same size core so I was able to remove the surround and mount from both transformers and install the Philco mount around the new hammond transformer.  It looks at least a little more original.  Not that it really matters.  It turns out that though the speaker is vintage Philco, it is not original to this model chassis so originality is out the window!
