6 pcs Nichicon FG Capacitors 100V 100uf Audio Grade

All mine measured 90 - 92uf instead of 100uf. Some of the caps I was going to replace still measured 100uf so I put them back in (but I would've preferred replacing them) , a tough choice since they were 40+ years old. 90uf is still within tolerance specs, but it's kind of worrisome for new caps to be off that much. The ones I did use seem to be working ok. I'm using them to rebuild very complex (for) speaker crossovers, and all 8 speakers are identical so when a cap is to far out of spec it's easily noticed.

For some reason all 6 capacitors measured from 86 to 89uf, and they’re new maybe they were stored in a hot place for a long time. I’m in the middle of re- caping a vintage amp but sadly these are going back.
