Also, the indicator light does not work (as expected).
I have seen the
suggestion to replace it with a CM7381. It looks like these can be sourced

with relative ease, but I wondered if there might be a better LED-based
longer term solution? I was also advised that OL-6003BP is good for the 15V
regulators, but these seem to be hard to find, any suggestions there?
For the OL-6003BP, the CM7370 will work nicely. The CM7003 is closer to
the original specs (before de-rating for voltage), but doesn't last as long.
