The 37-675 is a really nice set. I restored one that does not have the telephone dial tuner a few years ago. In regards to the speaker plug I think that there are pins and jacks for each individual wire on the speaker that allows the speaker to be detached from the chassis. I could be wrong on that since it has been so long since I restored it and have since sold the radio but I did have the speaker sent off to be re-coned so had to get it disconnected somehow.
