It was very common for the mains cable to break at the strain-relief
grommet, particularly if the cable is wound around the machine for
storage.  I replaced several mains cables during my time at an Acorn
dealer.

The replacement cables (with moulded plug) we obtained came from the RS
catalogue (http://rswww.com/).  These had "MARBO" moulded into the plug
top.

You can tell if the cable's been replaced by examining the black strain-
relief grommet - it could be a pig to get back into the hole provided
for it in the PSU case and you will usually find marks caused by
wrestling it back into place with a pair of pliers if the cable has
indeed been replaced.
