You are talking about the common mode choke on the filament supply. Not the Power Supply choke.Mine too buzzed, I too am on 240V - drove me nuts. I built my DRDs myself and added the Star Chief upgrade.
I eventually took it to someone with a scope and he traced it to the common mode chokes which are supposed to be an upgrade to the standard DRD. Once the chokes were removed the amps were dead quiet.
They are indeed excellent amplifiers.
