i AM REPLACING THE SPEAKER TO THIS RADIO WITH A MAGNETIC TYPE. CAN ANYONE TELL ME THE CONNECTIONS AND THE VALUE OF THE RESISTOR TO BE USED AS A SUBSTIUTE FOR THE SMOOTHING

MANY THANKS FRANK

Thanks Carl

The speaker I removed is a magnetic type but it has a 3 wire connection with a choke fitted to it. I have obtained a period magnetic only replacement and wonder if I should remove the old choke on the speaker and fix to the replacement:or just subsitute a resistor in place when I fit the new speaker. In either event I am unsure what wire goes where should I use the resistor

Are you sure it's not the output transformer mounted on the speaker, that would have 3 wires to the chassis, and 2 wires going to the PM speaker.

This model Sparton does have a 3 wire Audio Output transformer for the push pull duel output tubes. It may look like a choke, but it's not. Remove the Transformer from the old speaker. Mount it to the new speaker frame. Connect the wires as was with the old speaker.

Yup! It is an output transformer for the push pull. Got it figered out now, many thanks to you all
