The meter should be changed today. It is not that old.
I will remove the ferrites from the power cable when the new one is fitted, and see if there is any hum/buzz with the new meter.

Apparently caused by ants in the meter.
The "owner" of the meter tells me I need to put some product in the meter box to stop the ants. 

I reminded him that neither the meter, or the box belong to me, nor are they on my property, and as I don't have a key, how can I, even if I wanted to?

The conversation was cut short as they found a problem with the installation.....

And I think they have now found the root cause. A dodgy connector on the telegraph pole….

Meter replaced, connector (and possibly old cable) replaced.
Result? No hum/buzz audible on the vinyl side of my system.

I would never have found that fault, so I am happy it has been replaced

Thanks Kevin, that is good news on several levels.

I'd be surprised if they've replaced any cable - most grid issues can be laid at the feet of insufficient torque at the supply tails into meter.

After a period of silence, the hum came back last night, but at a lower level.
I dug out my old mains regenerator and have plugged everything but the power amp into it.
The result is that silence has now returned, and hopefully the hum/buzz is banished from my system.
