You won't hear the tone or it will be pretty weak. First it is AM. Second the 19.75MHz and 27.25MHz traps are pretty remote from the 21.25MHz sound IF.
You could see it on a scope. But just be sure you detect the tone on the VTVM by varying slightly the RF level. When you tune for the notch, the null should appear pretty obvious.
