I am trying to repair an old Emerson Model 646 radio for my mother-in-law. I discovered that the primary coil in the speaker matching coil is open. I have no idea what the impedence is or the winding ratio. Does anybody know what it is, or where I can find a new transformer?

Thanks

Larry

Hi Larry,
Your other option is to get a transformer from a scrapped set. Almost any radio that used a 3V4 output tube will have a transformer that will work well in this application.

All the Best,

Thanks guys, I will dig again in the junk in my garage plus I have e-mailed the two places that you listed. Since I started this mother-in-law project I am getting in the mood to play with some old radios again like I did years ago. I had a lot of fun back in the 50's when I was a kid, I remember the old radios that had the short wave bands I thought that was truly amazing that we could capture broadcasts from foregn countries. I also remember building crystal radios in Junior High School....those were the days, man if we could only go back : )

Thanks

Larry

You can. With every old radio you bring back to life.
