[time-nuts] AC Connector On HP 5061B

"What happens to a 5061 if I swap the power wires?  I can imagine some second

This is my concern.  Hence, I want to get it right in the beginning.

It used to matter back in the tube days when cheap radios/TVs didn't have a

power transformer.  The neutral was connected to the chassis and the B+ was 
derived from the hot line.  That gives you a hot chassis if you swap the 
power wires.  (The chassis was all hidden in plastic, at least in theory.)


What happens to a 5061 if I swap the power wires?  I can imagine some second 
order considerations that would depend on how the power transformer is 
constructed.
