I´m trying to recap my Sony F270 Amplifier , anyone knows where i can by authentic capacitors Nippon Chemicon 10000uf 63V ? i found these on ebay but i´m sure they must be fakes...

Something like this - check Dia and height against existing caps. These are 105 deg C also. The link you posted are not snap in types and anything out of Shen Zhen in China will be fake - count on it!

The caps on my amp are like the link I posted , not snap in , only dimensions are different 35mm x 60mm but I can't find them

If the footprint is smaller by a little that's okay (eg a bit shorter), you could go next value up or even 2, eg. 12000 or 15000uF which is likely the same dimensions. Capacitors like this would generally start with +20% or more of rated capacitance, where now they tend to start at -10% to -20% a lot of the time, so it's fine to go up a value.
If you can only find them in snap-in, well, that's the standard now... Either hunt around in case they're made but not stocked by all retailers, you may need to switch to another reputable brand to get the right footprint, another option is to drill out the pin holes to accept snap in pins. I would not go NOS parts in electrolytics as they do have an age function.

Oh, an oddball footprint, that might be awkward to change. Someone in here might know a good equivalent [emoji106]
The ones in the picture on post1 are on the amp and need replacement, the fake ones are on the link
Need replacement? or you want to replace them? There is a big difference 🙂
Those original caps probably perform as well or better than many new off the shelf replacements and I would bet they are comfortably within their original spec.
Just sayin 🙂

Those on the link are genuine Nippon Chemi-Con, but constitute a pointless replacement.
It is better to avoid the types of modern industrial style featuring low ESR and a high volume / capacitance ratio.

I dont think i can find those caps , is it ok if put the caps somewhere on the chassis and run wires to the PCB ?
I wouldn't recommend that.
I suggest find a spot on the board where you can drill the existing PCB tracks for the other terminal of a snap in type (10mm from one of the existing terminal holes) and still have the caps fit right in the board. Then scrape away a little solder mask around that hole and voila, you can use any of the myriad snap in options available.
From looking at your pics it should be possible. 2mm drill in a Dremel is a good bet or if you have a nice light hand drill run at high speed.
The other option is to spin up a new power supply board, or purchase one. As they tend to be fairly generic, this shouldn't prove too difficult, although you then need to fit it into the case.
I also wouldn't recommend that. The resistance of the leads, even though very low, and also the lead inductance would drastically impair the caps ability to deliver a low impedance point at the PCB where it was intended.
