6 pcs Nichicon FG Capacitors 100V 10uf Audio Grade

Nichicon FG Capacitors.. I had to replace the caps on a OLD Nad 2140 amplifier after 1 470uf 63 volt cap that failed that made a low Freq hum on both speakers.. SO it was time to change all the old caps since It was apart anyway. I have used the NAD for music and home theater for 13 years..The New Nichicon FG Caps looks to be very well made. But I dont understand why NAD used a 63v cap on a 59.2v supply. but the old cap did last 35 years but the replacements for that were 470uf at 100v.The Nichicon caps cost more but are better quality than what was used when new.I can recommend NICHICON Caps.. but be careful not to get FAKES.. I am sure they are many copies of the real ones !
