The problemo appears to be the voltage regulator 7805, which is frazzled. Measuring with a digi multimeter between two pins is the 11.5V (correct) and 0V between the other two (oh dear). So I have arranged for a new one. A big thanks to Bowood Electronics UK supplier of all electrical components for the heads up with a new part in the post.
I have prepared the ground by undoing all knobs to remove the PCB board and solder-sucker the part out from the board. We now sit by the pear tree and wait...
