I readjusted the audio traps and the tilt and this is the closest that I have gotten the IF response to the Magnavox service manual. As in the Magnavox service manual, the bode plot is inverted on both X and Y axis. So frequency increases from right to left, and amplification increases from top to bottom.

Frequency: 41.65mhz (chroma lower)
Target: 20% +/- 5%
Actual: 17%

Frequency: 42.17mhz (chroma mid)
Target: 50% +/- 5%
Actual: 51%

Frequency: 42.75mhz (chroma upper)
Target: 80% +/- 15%
Actual: 81%

Frequency: 45.00mhz
Target: 80% +/- 15%
Actual: 81%

Frequency: 45.75mhz (luma mid)
Target: 50% +/- 5%
Actual: 51%
