I am getting closer. I now am ensuring the sound detector (C2) voltage is at 2 volts and the video detector (C1) is at 6 volts. Over/under driving these voltages does affect the signal response. I also labeled the scope each time I snapped a picture so not to mix them up (label includes signal generator input and scope output). See below for where I am at:

The one concern I have is on the sound detector C2 response curve there is no real response dip like shown, my curve just starts to slope down continuously until it gets to the 41.75mc marker. Is it possible that I am still way off and need to push the 41.25, 41.75, and 42.75 further right on the wave form, that would put the 41.25 on the top of the first peak but currently is at 25% vs the spec of less than 5%.
