NAD 320BEE capacitor query

Hi, I've just opened up my NAD 320 BEE and noticed that one of the big 15000uF 50V capacitors in the power section is starting to bulge. I've found what I think is a suitable replacement but the service manual says the original cap has a 10% tolerance. The one I'm hoping to replace it with has a 20% tolerance. Is this likely to be a problem? Many thanks for taking time to read this.
