Source of replacement parts for Tenma 72-4045A Benchtop Power Supply?

I have a Tenma 72-4045A Triple-Output Benchtop Power supply with a plastic panel overlay that has turned a putrid color that is nearly opaque. Any chance of obtaining a replacement?

Did you try Retrobright?

I had never heard of that stuff, but have looked into it and it seems like magic sauce. I'll get some, many thanks!

Weirdly, also leaving the plastic out in strong sunlight can work to reverse yellowing, even though that's usually what causes it in the first place!

That's partly how Retrobright works but UV alone will also erase any lettering present on the plastic.
