I have one of these as a bedside radio...

With all of my radios which I use frequently and which incorporate a mains switch in a potentiometer I do two things - to avoid potentiometer wear and to increase safety:

Fit a switched 13A plug with a neon to the radio and use it. Fit a 1A HRC fuse to BS1362 to this plug.

The fuse would not have saved your radio in this case, but being in the habit of turning it off at the plug would. The 1A fuse did once save a mains transformer when I had a UU6 rectifier fail short - anode to anode.
