Opposite problem: disintegrating Old style Oval HP Receptacle ( ... was Old style oval HP power cords )

 

I have the opposite problem:

I have an instrument where the Old hp Oval Receptacle has disintegrated due to misuse or time.
It is so bad that it causes intermittent AC mains issues and is on the verge of shorting.

-? Does anyone have a?? spare,? good condition ? or?? NOS? hp Oval receptacle ?

thank you,
rick?
 

That is a PH-163 connector. Here's one:

Note that these were made in grounded and ungrounded versions, there are a few that used the ungrounded variant with an inductor to the case, the 331A is one example.

Also they are used for many other brands of test equipment in the 1960s, not just HP.

This one's in good shape. If you can stand the extra parts that come with it. $15 incl postage.

hi,

my disintegrated Old Oval receptacle in in an Hp 9100a Calculator.

it is so badly corroded and disintegrated that I can not tell if it was grounded or not.
The lower part of the 9100a case likely sat in water for some time.

According to Tony D ¡®s schematics, the ground pin in the connector was a ground connection for the electronics. One would assume that the external metal case was connected to the electronics ground. I can¡¯t verify this for you at present but it¡¯s highly unlikely not to be.

Some pictures for reference (not for sale), grounded shell versions from both Switchcraft & Tower, the bagged one is ungrounded one from Tower.





I've seen them broken from being shipped with the cord left in place, early 1970s IEC suffers the same fate.
