Yes, you need the cabinet loop antenna for proper AM reception. It is part of the input tuned circuit, so without it AM reception will be weak.

That said, it appears you have additional problems causing the crackling and related symptoms. Might have a bad tube or failing carbon resistor somewhere in the circuit.
