Also be sure the built-in antanna loop is connected correctly AND that it has continuity. If there is an open loop, AVC voltage will not get to the front end tube and the gain will run wide open also causing the exact distortion you have. Also check all the components in the AVC buss as well as the 150K resistor at the loop.

The AVC voltage also goes to the IF tube grid for gain control.
