I pulled the main PCB again which actually wasn't bad to do now that I've got the hang of it.
Getting the old sockets out isn't quite so easy though. I ended up cracking the old brittle plastic and removing the pins one at a time.
I had thought the replacements were identical to the originals, but I was wrong. The replacements are made from heavier gauge metal and are twice as wide where the old ones broke. They should hold up very well
