If the noise is only on AM, then its probably one of the transformers. Of course it also could be a bad resistor, connection or loose tube socket, etc, but I assume you already checked the other possibilities.
If you wiggle the IF transformer and the noise changes or gets worse, then that pretty much confirms that its the problem.
