relevant documentation available.
Just to add to the
Hi Ed,
I just tracked down Fluke and he offered me one, and per your advice I will
try and confirm the condition before purchasing from him (not that there are
alternate sources) . I have the schematics, but taking apart the hocky puck
is another matter, I pry and pry but get nowhere.I

Maybe noise WAS important, so they removed the regulator altogether. That
I suspect the reason was far simpler: 5 volts was available in the system,
why not use it and take the small amount of heat out of the box. There would
also be a reliability improvement, one less regulator per freq standard.

Anyone know the gain?
