Hi All, So I have two Genelec 8020Cs that are about 10 years old, one of them stopped switching on. I took it apart, fuse was blown, and I've traced the short to one of the two large capacitors on the circuit board.
Now from looking at the Capacitors, they seem to be from Samwha's SD Series with the following specs: 3300uf, 35v, 85C, 25 x 16 mm Radial.
The problem is, I can't find any capacitor from Samwha's SD Datasheet that matches these specs. The closest is 3300uf, 35v, 85c but 31.5 x 16mm, with a max ripple current of 2.5A. I'm guessing the 25mm is custom made for Genelec, and would have a correspodingly ca. 20% lower ripple current.
The closest replacement I can find is this: https://www.mouser.de/ProductDetail/...QB4xyb2g%3D%3D
This matches the specs, expcept it only has a ripple current of 1.7A, however this is at 105C, I'm guessing it would be higher at 85C.
My question is this - Would replacing these Samwha Caps (I would do both) with the Rubycons probably be ok, or is it a bit of a gamble?
Many thanks in advance
