Check the oscillator coil for an open tickler winding. You may not be getting any mixing of the broadcast signal to the IF frequency.
If you get the growl, then the regenerative detector is working ok. Back off the adjustment to the point just before it growls.
At least you know that everything after the mixer-oscillator is good ( detector and audio output stages).
