Good. Try turning the generator output down till you can just barely hear it from the spkr with the volume full up. Then see (hear) if you can get a peak from the 4 adjustments (slugs). To answer the question use an ac voltmeter set to it's lowest voltage scale across the spkr terminals. Since we are dealing with the IF stages the dial position (frequency) should have little to no affect on this adjustment. If it does something else is going on. Most of the time alignment instructions will say to set the tuning cap at max capacity (closed) for the IF alignment.
