I need to replace the speaker terminals board on my Yamaha A-1 integrated amp. I found a board on Ebay from a Yamaha CR-2020 that might fit if the spacing for the mounting holes is the same (3 1/4"). I asked the seller to measure it, but alas, no response.

Is that terminal threaded with a nut? If so can you just replace the broken terminal?

The gray plastic is broken off. I'm not sure how it works. I was also thinking about replacing the unit with some 5 way binding posts.

Where did you get that receiver? It sure doesn't look like any CR 2020 I've ever worked on; that terminal block is not the type normally used.

It's not a CR-2020. It's an A-1 integrated amp from 1978. Except for the colors of the little knobs, the A-1 speaker terminals looks the same as the CR-2020 speaker terminals.

Are you after an "authentic" replacement? If not, just cut a piece of plastic to cover the entire rectangular cutout, and replace those with regular binding posts

That is the Plan B if I don't find originals.
