Rather noisy inside, too - as I recall from a flight from Heathrow to Aldergrove. My first productive job was on the Line at Brize Norton, where the Belfast had the Tyne engine. Oil consumption was a bit of a problem - though I think we may have had tight limits stemming from the days when air-to-air refuelling was specified. So my guess is that the Tyne was not much of a problem on the Vanguard.
The electric system referred to seems similar to that of the Belfast, Britannia and Victor Mk1.
