Hi Terry,
I think you're right. It is a superheteredine. Coincidentally I had a TRF FI of a GE of the year 33 approximately. I have connected it and I hear a very weak station. It is 175 Kc.
The speaker is bad. The field coil reads 30 ohms. Impossible !!!!!. They must have rewound it wrong !!!!. Generally the field coils are between 1500 to 2000 ohms.
Thanks Terry.
And it is true, the TRFs are practically the same.
Regards,
Ferran
