How to remove McIntosh glass faceplate?

I haven't ever removed a faceplate on a 2125 but have on other pieces and once you remove the faceplate frame from the chassis it comes off fairly easy. You may contact McIntosh service and inquire if they offer a re-printing/screening service for that model. They are very helpful in keeping their equipment alive.
sometimes you can find a service manula here and look at the xploded schematic for dis-assembly

I agree with Mcintech. There are no instructions on disassembly, but as mentioned the exploded view of the chassis provides a layering of how it is assembled. That was how I always accessed the plate and light bulbs on the various Mc gear I have owned. Its nice to have confirmation that McIntosh is still offering faceplates. They DO take care of their customers. I have always been very satisfied with them. I hope the new owners continue the same level of service and quality. So far Audio Research seems to be the same company and maybe even better.
