I was informed that the 50hz buzz coming from above the cab was actually
the static inverter... Can anyone confirm or deny this? Information came
when I questioned someone about the 4D making this buzz from above the cab
about a week or so ago, when it was stabled, live, at Bayswater in the wee
hours of a Sunday morning.
