There were plenty of them, just like the substandard Sanyo MBC-55x series, that
were modified with a different value resistor to change the cutoff point of the
power supply when the onset of high current requirements came about. I remember
seeing 5150 power supply mods listed in many magazines back then and have done tow
or three as well but I couldn't tell you for the life of me what resistor and what
value, even on the Sanyos where I must have done 20 different machines with a
similar mod when we had a micro club in central Illinois.
With all the technical manuals and old magazines that people on the list have I'm
surprised that one of the IBM tech journals or field service manuals doesn't have
the mod listed.
Unless it's a definite requirement to have an exact replacement you might take
someone up on a clone XT power supply since I've seen them up to 150 watts in
generic cases. I know the first barebones, no name clone had at least a 135 watt
if not a 150 and it should fit like a glove.
