Similar to what another poster suggested, but more direct - assuming the schematic shows that only the live side is fuse protected inside the HP, then if you take out the fuse on the rear panel, and see which prong on the connector connects to it, that should tell you.
- unless both sides are fused :-( Ian. ----- Original Message ----- From: "Jeffrey Okamitsu" <[EMAIL PROTECTED]> To: "Discussion of precise time and frequency measurement" <[email protected]> Sent: Thursday, October 02, 2008 7:56 PM Subject: Re: [time-nuts] AC Connector On HP 5061B "What happens to a 5061 if I swap the power wires?

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. -- These are my opinions, not necessarily my employer's.
