Some pictures.

Almost all of the electrolytics under the chassis have now been replaced.
But I missed two when I was writing up my "need to order" list:

You can sort of see them above, partially hidden under the two 1.2K resistors.
I noticed that, as I observed Saturday evening, that the right channel sound is still not as bright as the left channel sound, although the volume of both seems equal now. I may have to take a look at the tone control board, plus replace those two electrolytics that I missed.
A photo of the 440-T in operation - notice that, without the faceplate, it looks very similar to the 4400 without its faceplate:

Now, for your edification, I present the next two pictures as examples of what not to do to the extremely delicate faceplates of these receivers:

Don't polish, soak, or otherwise attempt to clean these - you can only make them look worse, not better.
Now, other than some more electronic work to see why the right channel seems "muddy" compared to the left, I need to decide whether I want to try Skyscraper's idea of transferring some artwork, or just finding a junker 440-T with a better faceplate. Since I probably need a speaker switch, a junk 440-T might be a better option. So comes the challenge of finding one...
