I have a Deforest Crosley radio model 1722. I am restoring it. It did not come with a field speaker and I do not know the resistance of the field coil. The schematic does not give the value of that coil. Does anyone have any ideas or have the speaker.
Hi David
I have a Deforest Crosley Replacement Parts And Circuits 1925-1934 It list the transformer output as part # R4209 and Driver transformer as part #R4211.It list the 1721 &1722 together and one is THE EXPLORER & the other is called the NAVIGATOR. So far no values.
