I was looking inside my B&O M100-2 speakers as the previous owner had said that he recapped them , I discovered that he has substituted most with the incorrect values albeit by a small difference but will this effect their performance?
They do sound very very good btw .
is it ok to do so ? Should I replace them for their correct values?
Surely the wrong values will have some effect on their performance?

C4 5uf 4.7uf
C5 8uf 8.2uf
C6 50uf 47uf
C7 16uf 15uf
C8 8uf 8.2uf
C9 12uf 15uf
C10 50uf 47uf
C11 4uf 4.7uf

You would have a hard time finding the correct values, as what used to be standard values many decades ago are not standard values anymore. I think the previous owner tried to get close to the old values with the values that are now available. The old capacitors probably had 10 % or 20 % of tolerance, so any differences smaller than that are apparently small enough.
Maybe you could replace C9 with a 12 uF film capacitor and C11 with a 3.9 uF film capacitor.

Thanks for your reply.
I have managed to locate all of the correct value caps from different companies but at over £100 is it really worth it?

I would say no too re: values.. But they looks small. Whats the Voltage rating marking say on the new caps? OK, I see now 100V - should be ok.
