Hi everyone,
I have a friend's radio to repair. It is a zenette with 5 valves: 57, 58, 57, 47, 80. I have not found any scheme. It looks like a RFS with no reaction. The problem is that the RF transformer in the third step is cut off. The primary reads about 750 ohms. The secondary cut. Trying to see how the transformer was, the primary has been cut. A disaster !!!!!.
I do not know what to do. I've rewound Philcos coils, etc. But this case is impossible. It is small and I have no data. It was covered in wax.
Question: Could the coupling be made between the 58 and the 57 resistors?
Can you give me a solution? At the moment nothing else has occurred to me.
Thanks in advance.
