Replacing the power suply
The original power supply is of the linear type, which means it uses a bulky transformer. This power supply has a few disadvantgages:
* It is bulky, which is not very convenient when you're carrying your NES in a pack sack.
* It covers almost 3 sockets when you plug it in a power bar.
* Mine is old and has started to fail (you need to pull the plug in the right direction to make it work!)
* It has an AC output, which is rarer. It is hard to find a perfect replacement looking at the NES schematics, I saw that the power coming from the power supply is converted to DC and lowered to 5 volts using a simple lm7805 voltage regulator. This means that giving 12 volts to the NES will not damage it (however, please note that the regulator will generate a little more heat). Since the NES expects AC, you can supply the NES with DC power without having to check the polarity.


Switching power supplies are usually smaller than linear power supplies, so I have used the switching power supply that came with my old cable modem. It gives 12 volts up to 0.6 amps. So far, it has worked flawlessly with the NES. 

tak wiec oboje mielismy racje ;-)
