You just got a 5061B and you don't want to open it? It is so cool
looking inside, how can you resist?

See the pin assignments in the 5061 manual:

But, NEVER, make a power cord for something as precious as a
5061 without actually checking pins from the inside. On some
models 5065/5061 that I have HP switched the pin assignments.
See, for example,

http://www.leapsecond.com/museum/hp5065a/conn.htm

> Each of the pins on the jack at are assigned a letter. "G", "A", and "B" (I think).
> "G" is ground as it is connected to chassis (confirmed with am ohmmeter).
> Does anyone know which of the other two pins is AC hot and which is AC neutral?

The other way to check it is pull the fuse and measure which pin
is connected to the ends of the fuse holder.
