Brenda is talking about the IF transformers.

You did OK, except for A3. Philco wanted you to tighten A3 (this is what they meant by completely clockwise), adjust A1 and A2 for maximum output, then adjust A3 for maximum output, and finally adjust A4 for maximum output.

Try it again, it should get better.

One final thought. When you're finished, your 620 kc station may not come in exactly at 620 on the dial no matter how carefully you perform the alignment. Non-linearity in the circuit, especially as these components age, may cause this. Not to mention the fact that Philco did not provide an adjustment for the low end of the band in this set.
