Wondering if anyone has an old Eveready 753 battery pack they no longer want? OR, the socket used on this style of battery?

Is that the 45 volt one? If so, I made some PCBs for my battery valve P/S that have a re-creation of that socket.

Ian - hi, it's a combined 90/9/7.5 volt battery.

Octal valve socket?

No, I remember those battery sockets. Different to anything else.

It's very cheap to get prototype PCBs made in China these days. Just need VERY accurate measurements of pin dimensions and juxtaposition. And some good PCB cad software (which I have).

There are photos of it and it looks a lot like an octal. I often use the base of a dud valve on sets as you can wire a specific radio to the pinouts of the socket on the PSU.

Some sets & batteries used Fahnestock clips & pins; Both of which are gettable.

Hi John,

I have an Eveready 756 battery pack that is 90/9/7.5 volt battery and the socket on that is definitely not octal. It has eight pins in a circle with a center pin that is to one side as an index.

If that sounds right to you let me know and I can scan it for you so that you can make a reproduction. You may even be able to use an old wafer octal socket if you fill in the center hole and drill the index hole. I will measure it to make sure if you want.

Regards, Frank.

P.S. My email is open.
