Hallo,

i'm trying to repair my old Zyxel Prestige 100 ISDN-Router. The power
circuit of the router has some problems... The mosfet of the switching
regulator was kill and the resistor R99 blow up. I was still able to
identify the mosfet ( n-channel mosfet 15N05) but the restitor is too
damaged. I can only identify the last two rings (gold and silver) so the
value must be below 1R.
Does anybody know the correct value of resistor R99? Or does anybody
have a schematic for this router?
