Default Looking to replace 6800uF 50V filter caps

Any ideas? Would higher/lower voltage capacitors work?


Thanks

As a rule of thumb: voltage should be the same or higher, never lower

These capacitors should be very easy to obtain at either Newark, DigiKey or Mouser. Never replace with a lower voltage unless you know exactly what you're doing in that application. Do not go more than 20% over the rated capacitance, or you risk drawing too much current out of the transformer and bridge rectifier.

nigelwright7557: I don't know what voltage the power supply is (couldn't find it for some reason...the service manual labels it as B2+ and B1+). As for the power, I believe it is 45W to each channel.



I found these to at newark.

ILLINOIS CAPACITOR|688LBB050M2CF|Aluminum Electrolytic Capacitor | Newark.com

PANASONIC|ECOS1HA682CA|CAPACITOR, 6800UF 50V CAPACITOR | Newark.com


There is a single Elna cap at digikey that I know would work, but they're 15 bucks a piece. Would either of the ones I linked be ok?

It would be cheaper to buy them here.
