I have two original Nintendo switching power supplies. One works and the other doesn't.

The only thing I know about the non-working one is that a few years ago I had it in a DK cabinet that I had installed both Mario Bros. and Super Mario Bros.

While I was working on the game the adaptor I made to allow switching back and forth between the two boardsets partly slipped off the finger board that connected it to the main harness, which resulted in a smell like something was burning.

I guess it's time to get back to it and I was wondering if anyone can point me to a cap list for these power supplies so I can at least shot-gun the non-working one and probably re-cap the working one before it fails anyway. (There is a third power supply in a game that I sold to a friend about 8 years ago may need to be re-capped soon also).

Lastly, a pointer to those who fix Nintendo power supplies would also be appreciated.

Thanks a lot.

PP7B cap list...

Just capped this today. There are 2 boards inside with harnesses that tie them together. - Barry

Board without heatsink:

330uf 200v - C6/C7
10uf 16v - C22
47uf 35v - C13
47uf 16v - C18/C19/C20/C30/C31/C32/C37/C38

Board with heatsink:

47uf 35v - C11
1000uf 50v - C10
47uf 16v - C36/C12
3300uf 10v - C15/C16/C27/C28
1000uf 25v - C21
10uf 16v - C2/C35/C34/C24
100uf 25v - C23/C33

I bought all my caps from mouser and I think it was around 13.00 for the kit. There are 2 caps that are over 3 bucks each which is why it costs so much. Fairly easy to do though.

To add to this - since this is a switching supply, you MUST use low-ESR type caps for the Vout caps of the regulator circuit.

Thanks.

Can you direct me to any "How to" pages and also "Cap Maps"?

I don't know of any for these power supplies. The nice thing about them is all of the caps are clearly marked and the boards are small so they are easy to locate. - Barry

Ok. I've never actually opened one of these power supplies up and I didn't want to get stuck.

Thanks.

www.mouser.com They are very reasonable. It lets you search by microfarad, voltage, size and several others. Make sure when you order you pick USPS Priority as it's cheaper and faster than UPS. - Barry
