Many times the loop antenna is the D.C. path to the first grid of the converter/mixer tube for the AVC voltage.
With no gain "throttle" on the front end of the set, it's running "wide open" and stations will be overloading the front-end, and then the IF stage
and the detector causing the audio distortion you hear.
