So if you apply a 460kc signal to the grid cap the 77 mixer tube do you get a good loud signal from the spkr??
If not peak IF trimmers for max audio output. If that doesn't help much check voltages around the mixer and IF amp tubes. You may have a bad resistor causing low voltage on one or more of these stages.
