Admiral 14R12 Restoration

[bandersen]

This IF design uses over coupled IF transformers rather than stagger tuned. One stage is peaked to 25.3 and the other to 23.1. That's an economical design that flattens out the response somewhat but not as good as a real stagger tuned with multiple stages each peaked to a different frequency.

Did you follow all the setup directions including replacing the converted tube (6J6) with one that has pin 1 clipped off ? As mentioned above, it's important to use as low a signal level as possible
