I would check the speaker or hook a different one to the set. It could be that the cone can't move freely. The values of the caps/resistor look pretty average. If you want to lower the highs increase the value of C-7 to .015 - .02 @630v. You can go larger if you like but it will start to sound muffled.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
