Hello i have a question today
I was fixing my old crt tv and i decided to make compleete recap for all electrolytic capacitors. Well tv kind of work, but it will be 30 years old next year and i wouldn't want to see any smoke before then.
So i went online and bought a bunch of caps, i kept to mostly known brands for bigger or high voltage ones (Rubyco,Elna Nichicon) for smaller ones below 100uF and 25V i just bought whatever they had, because most of the smaller caps were advertised as "audio caps" and i didn't want any snake oil so i ended up with a buch of daewoo caps. At least a brand i know and not generic black ones without any logo on them.
But something isn't right with one of those bigger caps. I might be paranoid, but i thought, before i put them in i ask wiser people about their opinion.
Caps in question are suposed to be Nichicon Chemi-con 470uF / 50v
what they are i am not sure, they have JAPAN printed on them, small font capital leters, next word is NRSA, CE85*C, 0035 Some kind of "Nc" logo and cap voltage and capacity
I am concern, because they measure a little low , (on ut139c non the les) 430-450uF range. They might be just old or unformed but who knows
I also have few TEAPO caps 470uf /63V but since oryginal caps in circuit were all 35-40V , 63V seems a little bit much.
What do you think?
