Thanks Ron!

Yes, this helps. It's nice to know I followed the wording of the changes correctly.

I'm not sure if it qualifies as a find, as I purchased it on our favorite auction site.

It was a short drive to Western PA to pick it and I was the only bidder. The price seemed reasonable for such a nice radio. The finish on the chairside part is OK as is.

Anyway, the chassis has been worked on a lot. The Nostalgia Air schematic is not the same as the one you posted, but changes are listed which do match your schematic. The radio seems to have parts from both versions. Some parts were missing altogether. I have ordered a clearer schematic. I wired the radio according to the original and then according to the changes. I like the changed version better, but the tone control effect is still very subtle. On a good quality signal you can hear the tone change, but it's much more gradual than any other Philco I've worked on. It's almost as if the engineers wanted a continuous effect. Sure uses a lot of parts for such a small amount of control. Still, a very nice radio and the connecting cable (must be 20 feet long) is in good shape too.
