Welcome to Quilting Board.
Ouch! that is going to be hard to find.
I was about to give up. I had found
https://www.naehmaschinenverzeichnis...hinen/phoenix/ which showed a couple of machines with that kind of plug. Thinking that you would need to go to some German sites, I decided to try one more thing. I did an
image search for a site specific for "lead cords" and found what I think may work for this machine. It is a Pfaff cord that looks to be the same configuration
https://www.sewingmachinesplus.com/p...-332003-12.php Then when I put
lead cord 70-332003-12 in a google search I came up with a Canadian site
http://www.smscanada.com/viewproduct.php?ID=5196 however, you will need to find a dealer near you. I did a search on that site and it looks like there might be another one in white that would work - 90-223010-23. Once you have a number, you can search by that number and 'lead cord' as it looks like there may be some other places that have it.
