1931 Philco Model 70 Missing Speaker

As part of my searching on the site I found the article about the speaker problems in Cathedral radios in the library. That was the information that made me start to think that the idea of using the 4/8 ohm speakers may not work with the transformers. That 0.7 ohm impedance was the first time I'd seen one like that.
