I've just run a cable from the left interconnect to the earth pin on the plug for the speakers power supply. I've also put a resistor in the middle of the cable. There's probably lots of reasons why this is a very stupid thing to do (which is why it's currently unplugged!), but it cured the hum nicely. I suppose my problems come when the cable becomes detached from the earth pin and wanders over to live or neutral...
