Philco 20A - Electronic Restoration Questions
#23

I found a tear in the paper speaker cone and I saw a "how-to" repair online using Elmer's glue & coffee filter paper.

And I gave it a shot. It seems to be working well, the sound is coming through just fine. I can paint the repairs if I wanted, but the dried result actually looks less conspicuous than the picture shows:
