I ONLY sell name-brand, top of the line Japanese and North American-made capacitors sourced from the distributors themselves. (See end of listing for which brands I choose and which I don't)
There is no issue buying Capacitors on eBay, SO LONG as you do your research, but any listing that are suspiciously cheap, or a store that has tens of thousands of sales, I would be skeptical of. Amazon is the worst possible place you could purchase from, alongside random websites.

Don't get overcharged by certain CONSOLE websites that are going to send you the cheapest capacitors on the market, or possibly receive who knows what kind of capacitors from other sellers..I had a hard time going through reviews, reading spec sheets and figuring out which buyers to buy from, who to trust etc, and it was ridiculous. So instead, I went straight to the Japanese and US based manufacturers who originally made the capacitors for the consoles and who make better, higher end replacements. Now, I have it all here for you all ready to go

These capacitors are sourced properly, not from 3rd party sellers, amazon, ebay etc. All of the capacitors I use and sell are purchased directly from Japanese or American manufacturers and their distributors.



A bit about me and what I do
I refurbish game consoles, and in the last 2 years or so have specialized in just the Xbox platform, but I have recapped and refurbished pretty much every console from the Ps1 through the 360. I will not sell a capacitor that I haven't personally verified myself on my own consoles. For instance, I ordered a regular CPU recapping kit from someone, and I got JCCON caps which worked, but they were HALF the size of the original caps and they ran HOT. They did still work, but If they can't even be bothered to measure them, who knows what ripple current, dissipation factor, or leakage current they chose when they bought them. Every capacitor that I sell is either the manufacturer OEM's modern replacement, or the closest possible cap that you can get.


Included in this Kit:

-1x 10uF 16v Capacitor
-2x 100uF 6.3v Capacitors
(3 total capacitors)

Enough to completely recap your S-type controller

I do NOT use WURTH capacitors. They are a German brand, but their fabs are Chinese and generally are of a lower quality than other brands. I very rarely use Panasonic, for the same reason. However they do have some caps made in Japan, so those I will use.
Other brands I stay away from are Murata, Sanyo (Japanese, but also mainland China and commonly faked, even through major distributors)

Brands I DO choose from include Nichicon (Japan), Chemicon(Nippon, also Japan), Abracon (North America), KEMET (North America), Rubycon (Japan), KYOCERA AVX(North America)
