   OK.   
   What is known:   
      
   a) Scope is blowing mains fuses.   
   b) RIFA -branded caps blew up.   
   c) The power-supply board was affected.   
      
   Suggestion:   
   1) Remove the power-supply board.   
   2) Replace all, repeat: ALL the capacitors on that board of any nature, type   
   or style with the correct (but modern) replacement type.   
   3) Check each other component on the board. Diodes, regulators, transistors,   
   whatever.   
   4) Replace any that are either bad or the slightest bit questionable.   
   5) Replace board - carefully (now might be an opportunity for a DBT to 'do its   
   thing' - but a metered Variac would be better).   
      
   I kinda-sorta think that will do it. KISS and all that.
