Philco 40-180 Schematic help.

Schematics downloaded for this Philco 40-180 do not agree with what is in my version of this radio.
Downloaded schematics show an 8 tube model with this tube lineup:
1232, 7J7, 7B7, 7A6, 7C6, 41, 41, 84

What I have is:
1232, 6J8G, 7B7, 7C6, 41, 41, 84

Grillcloth.com has a radio finder feature that seems to indicate that the 7J7 and the 6J8G are interchanged on this radio (per Howard Sam's Red Book - 1st edition).
But these tubes have such different pinouts that the schematics have to be radically different.
7J7 pinout:http://www.nostalgiaair.org/tubes/7j7.htm.
6J8G pinout: http://www.nostalgiaair.org/tubes/6j8g.htm.

Does anyone know where the proper schematic can be had for a 40-180 that uses a 7 tube line-up with a 6J8G in use?
