The modulator adjust is likely for the modulation or output level, not the carrier frequency. There is a slug in the tuner for each channel that can be reached from the front of the tuner. Set the fine tuning in the center of it's rotation and tweak that stations oscillator trimmer. Adjust for best picture then go through the audio alignment procedure outline in the service info. It's all done by ear and pretty simple to do.
