I’m currently upgrading my Warm audio WA8000 and am trying to upgrade the capacitor that comes after the capsule to the Vishay ERO MKP 1840 (this seems to be the one people are saying is in the c800). I’m pretty new to reading schematics/ electronics in general and I’m stuck on what capacitor would make the most sense. I’ve found a Vishay 1840 rated at 630v (warm stock is 400v) and a Vishay 1841 MKP ERO rated at 400v with 5% less tolerance (warm stock is 10%). Anyone have any idea which is correct? What does the ERO mean? Thanks!
