When performing an IF alignment, it is important to keep the signal as low as possible so you just hear the audio out of the speaker. With a ac voltmeter across the speaker with volume at max you start with T12 secondary and peak it, then go to the primary and peak it. If the volume jumps up, turn the signal down again. This is critical as the AVC circuit cuts in with too much signal and you will never find the peak.

If you keep tuning the transformers without any success, they could all be so far out that you may have to start by injecting the signal at the grid of each stage and peak one transformer at a time.

For example:

With a small cap, .01 or so in line with your signal generator, inject the IF frequency into the grid of the 2nd IF tube, (pin 1), and peak T12 again with low signal. Repeat the process at the 1st IF tube grid, and the go to the mixer grid last. All the while you should have to keep reducing the signal as I mentioned earlier. If each stage peaked, you can now keep the signal at the mixer grid and then re-peak every thing again starting at T12.

If along the way you find a transformer that won't peak, then it is likely bad, or the tube is not amplifying. Each stage while working backwards to the mixer should have gain requiring you to lower the signal. It is not impossible to have more than one bad stage, and this will help you find it.

I forgot to mention that the sig gen should be modulated with 400 Hz audio during this test.

Hope this helps.
