cap can uf value

Hi Skip, I was looking at my bogen he10 the other day and the cap can for the main filtering section is 80uf,30,10. Its original but the schematic shows a 10uf,10 cap can. The other cap can  is same as schematic 5uf,5,5,5. when time comes to replace the main one should I use the same values as the can rather than follow the schematic. It sounds and runs great but i was just thought it was strange that the values were so different and wondered why  Bogen did that.
