I went through all of the steps through the video IF and trap adjustments that are done from the top of the chassis (step 11 on the alignment table). I was able to do all of the minimum voltage adjustments with the VTVM on the 1.5V scale. The signal is being fed into V102 pin 1 at 300mv through a 1500pF ceramic capacitor.

The max/min swings on the VTVM while adjusting the slugs were pretty minimal. That didn't exactly fill me with confidence! Could my input signal strength be too low at 300mV?

I have not encountered the problem described earlier where I had to increase the VTVM DC range to 50V. I must have seen that while going through the adjustments on the bottom of the chassis for maximum deflection on the meter.
