AW12 output TX

[Corby Dawson]

Hi,

 

I'm working on a singe dial AW12. It has a single 12" speaker that I think is a Jensen.

The amp has 2 type 45 tubes.

I'm going to send the speaker out for repair as the cone and voice coil are missing.

I was Ohmming out the field coil and output TX and it looks like one side of the output TX is open.

 

Does anyone have a good output TX for sale?

 

Also there are 4 wires coming out of the speaker, I see 750 Ohms between one pair and no continuity on the other.  I'm assuming this is not good?

The schematic I have for the power unit/amp shows the wiring for two speakers. Anyone have the wiring diagram for a single speaker?

 

Thanks!
