I’m trying to restore a 1931 Echophone Echoette, Model 40 radio.
The speaker was completely destroyed however.
It’s a 6 1/4″ diameter speaker with attached field coil.

Would anyone have something like this available?

The schematic in the Riders manual (Vol 2) says ‘In the later models the speaker field is in the negative lead and part of the drop across it is used to bias the grid of the power tube. A bucking coil is used in the speaker to keep the field ripple out of the voice coil.’
Note also says the field coil is 2000 ohms.

Thanks Gary,
Any information is useful.
Would you know of anyone in Canada that would rebuild a speaker? I have a new cone for it but wouldn’t know how to go about replacing it.

Thanks again

I don’t know anyone in Canada who can do this but you might try starting a new topic with a new title such as ‘Can anybody recone a speaker?’
I see from a google search that there are audio stores around the country that recone speakers, and there are a lot of YouTube videos if you feel like trying it yourself.
