Repair the Power Supply of an Apple TimeCapsule

In the first generation of Time Capsules there was a quality problem with the capacitors in the switching power supply: a lot of them broke due to heat problems after about 17 months There is an excellent instruction on how to repair the device. Nevertheless the information which capacitors to use is missing. In this post I present a short instruction including more detailled information on the capacitors.
