I just was given this Electrohome/Dominion radio, a Canadian radio, and it hasn’t been touched. All the caps and resisters are original and I haven’t changed anything yet, BUT, what I do need is a speaker. There isn’t even one there to repair. I was hoping to replace all the electrolytics, caps and out of range resistors and then fire it up on a dim bulb but I can’t proceed without a speaker.

It originally had a 10” dynamic speaker and I was hoping that I could get some advice as to my options on how to replace it. Getting an original may be impossible and if I replace it with a permanent magnet speaker how would I go about connecting it correctly. I have read up somewhat on that process but figuring out what value resisters or additional caps may be required and where they are connected is beyond my abilities at this time.
If there are other options other then a PM speaker please pass that along as well.
Any advice at all would be greatly appreciated.
