Nikko Alpha 450 replacement relay

Hello All!! I'm currently working on a Nikko Alpha 450 power amp. It has a dead speaker switch relay, I know it's bad because I've switched it for its partner (speaker A B situation) and the other works fine. The coil seems dead. It's a Takamisawa MAT 2B-119H. I'm having a little trouble figuring out a modern equivalent replacement, any help from those better at sourcing these than me would be greatly appreciated. Thanks!!

Aside from taking the time to swap something for another, it would have been much easier and faster to use an ohm meter to test the 48 volt coil for being open.

So just to clarify, the other relay works in both the A and B speakers position?

Thanks for your reply. That was actually my first move and it did test open. I’m one of those weirdos who sometimes doesn’t trust his own eyes. It was easy enough to swap them for confirmation. Yes you are correct, the other relay works perfectly fine in either position.
