For reference here is the SAMS IF circuit schematic with the Zenith Service Manual test points and coil/transformer part numbers. Also here are the abbreviated alignment steps:

1. L4 41.25mc (Bottom Tuned) - set to minimum response
2. L4 41.25mc (Top Null) - set to minimum response
3. Directions say not to go back and adjust L4 (this is what I did to get the option 1 response curve, the response curve in option 2 is closer to correct, but that means other adjustments are needed)
4. T4 Primary & Secondary - adjust to match response curve
5. L1 41.25mc - set to minimum response
6. L2 47.25mc (Bottom Null) - set to minimum response
7. L2 47.25mc (Top Tuned) - adjust to 47.25mc (some interaction may exist)
8. L3 39.75mc - set to minimum response
9. Recheck L1, L2, L3
10. T1 45.75mc - adjust to match response curve
11. T2 45mc - set to maximum response
12. T3 43mc - set to maximum response
13. Recheck to ensure marker locations and attenuations
