After I had it put back together, something I had noticed about one end of cap (40) kept bothering me, so I took it back to the basement workbench, took it apart again, and had another look.

You guessed it - I did not have the end of (40) that goes to the plate of the 7B5E output tube connected correctly. DUH!

Once that end of (40) was soldered to the plate of the 7B5E, the tone control began working correctly.

So now the 35A is back together again, back on the shelving unit in my home office again, and is totally complete.
