Well thank you both for this information. Being unfamiliar with these old radios, the modern speaker idea was my first thought since we don't have a speaker at all and it seemed like a good idea at the time. 

From what you tell me, that's a non-starter since it is a family heirloom. I'll talk to my friend and explain that it might take a little more time, but the search for the original 70 speaker might be the best way to go to get this radio running again. 

You saved me from a lot of work on a project that I don't know much about. The fate of that radio would probably not have been good without your help. 

Thanks to you both for your quick and knowledgeable replies.
