Hi Sandy_r.

I did rewire the transformer to terminal wiring as it was missing...someone had started to rewire the speaker as a regular low impedance extension speaker. There is no energising supply needed. It's just a regular speaker with an output transformer on it. As I mentioned, the switch is wrong and disconnected.

Thanks for the help and information, I think I have what I need now to use it as designed. Someone will have a copy of the actual instruction leaflet somewhere.

I have some plans for vintage TRFs and the like.

Regards

Simon
