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.
