   I'm not sure it's worth the expense, because there's another fault   
   with this scope that will most likely still be present even if the   
   present one is fixed. In fact, this 'other fault' may well have caused   
   the current one. This 'other fault' involved the displayed traces   
   suddenly turning extremely bright, accompanied by lines of dots. It   
   materialised only rarely, but I was out of the room when the scope   
   went *phut* so have no idea if there's any link to the current fault   
   or not.   
   I'm beginning to suspect those caps may have failed at some time in   
   the past, because for them to go *bang* with that amount of crap   
   sprayed everywhere must surely have resulted in a great deal of acrid   
   smoke being released - yet there was none discernable. And if those   
   caps fail open circuit (which they both did despite being X2 safety   
   ones which are supposed to fail short) then the scope can contintue to   
   function pretty well as normal so long as the mains supply is   
   reasonably clean.
