Hi Megastat 16,
I can give you a good reason. I was using an HK Citation 4 in my bi-amped system with a subwoofer. Every time the fridge would come on it drove my subwoofer and it's amp nuts. I regulated the B+ supply of the Citation 4 and the issue was solved.
It is not trivial to to get power supply rejection in vacuum tube circuits.
