Hum on the ICM line is often caused by using B battery instead of A Battery. Try testing the output from the power supply with a butt set. Go across B Battery and B ground and listen to the power. it should be noisy.
Now try the same thing with A battery and A ground. It should be clear. If it's not, then you could have a defective power supply. If it's clear, then make sure you are actiually wired to A ground and not B ground. Make sure that all your grounds a re commoned.
Let us know what develops.
