For the sake of completeness, I ought to say that new multi-section electrolytic capacitors, which would be a direct replacement, are available from specialist suppliers but at a price that would be more than the value of the set. EG, triple 40µF 525V twist lock fitting $40.90 US plus shipping:

There might well be other sources a little cheaper within mainland Europe, but those from Farnell or Cricklewood will do the job just as well, at more realistic prices.
