Reply to "Atlas O MP15 with ESU Loksound Select L sound decoder upgrade"

Hi Bill,

Yes, I agree that it is indeed those two green capacitors that are storing the current for the keep alive feature in the 4.0 XL decoder. They looked just like the ones in the picture for the Power Pack Maxi and being these XL decoders are for even larger current consumers than O scale, e.g. G Scale, I am presuming they are hopefully at least the same size as the Maxi. As for the capacitance, I did not see any reference to the actual capacitance in the XL decoder manual, nor did I see any reference to the amount of capacitance in the Power Pack Maxi web page, at least on the English version of the Power Pack Maxi ESU web page… However, on the German version of the Power Pack Maxi web page, you can see a reference to 5 Farads in the German text .
