Need advice on replacing ceramic capacitors (in Klipsch ProMedia 2.1's)

[MWink]

It seems that a pair of ceramic capacitors blew in my Klipsch ProMedia 2.1's. I found this ( http://christopherbradshaw.net/The_Project_Bin/Klipsch ProMedia 2.1 Power Supply Schematic.gif ) schematic, which seems to indicate that they are 0.047uf (C119 and C120). What I'm not sure about is the other specs (voltage, etc.). Can anyone suggest appropriate replacements (hopefully available from somewhere like Mouser)? I appreciate any advice.

We would need to know what size they are. Can you measure the caps or are they too badly damaged? If so then can you measure the pads?

If they are small like that then you need to be very accurate.

If you measure the pads, then provide the measurement indicated by the 4.3 below

If I have that measurement I can find a cap that will fit.

Looks like they need to handle those transformer secondary voltages, 40 for the one, and 80 for the other?

I'm assuming those are 250 volt caps. There is really no reason not to provide plenty of extra voltage rating, since the cost difference is nil. But who knows, maybe they cheaped out and went with 100V or 120V caps. At any rate, I'll provide a 500V+ replacement part. They will cost around 50 cents apiece.

Luckily, they're not surface mount. I think they're 5mm radial style. Would these be a good choice: http://www.mouser.com/ProductDetail...GAEpiMZZMt3KoXD5rJ2N/5Yhuu121M%2bIaMH1TlZ3O0=

I would rather spend more and get quality ones that will hold up better than the originals. Thanks for the help!
