Hi All,

I have seen these before but don't know what they are called so I can track a couple down. Thanks!

3-Pin HP/Burroughs/NCR connector, depending on the max oval dimension and pin spacing - there were IIRC two (maybe 3) sizes.

I have some NOS cords listed, deep in the classifieds:

viewtopic.php?f=15&t=281280

They fit the most common "HP" size, and have IEC color coded leads - you'll want to open up your instrument to verify the polarity if a hot chassis or fusing is used.

You can find them if you search for "TV Cheater Cord" as well

The cords occasionally show up at hamfests and surplus stores. Sometimes the seller doesn't know what they are and prices them really low. Sometimes they know they are in demand and price accordingly.

It's called a PH-163. Very common on North American business machines and test equipment before the IEC connectors became popular.

Still being made for replacement use, at least until very recently. Should not be too hard to find one.

Note that NEMA, or whatever orginization that set a "standard", chose to reverse the L and N connection convention used by HP, so there are two types or cords. Usually either will work in the other's place.

Thanks folks! Much easier to locate something once you know what to call it. A friend of mine said he might have one in his stash, so I will dig and see if I can find one this week. Findem, if I don't find one I know where to get one.

Those power cords usually sell on eBay for more than $20. I have a stash that I won't sell because some equipment can't be easily changed over to IEC. If you can make the change I suggest doing it; you will need to cut metal.

You know, I have been thinking about that. The unit is a mid/late 50's ampex suitcase amp. Its already been modified with an extra mic jack and an external fuse holder. There is sufficient room to put in an IEC. I don't happen to have a panel mount IEC laying around either though. I guess I will see if my buddy has one (if so it will be free) and if not I'll have to decide. Findem has 'em at a good price but then there is shipping.

Anyway, thanks for the suggestion.
