Good afternoon, Harry! Wow, how cool that I'm finally seeing others encountering the same discrepancies. When I restored my 46-480 a couple of years ago I, too, discovered that R300 should be a 4.7 kΩ resistor (the original Philco schematic and parts list were at odds with each other, but my chassis had a 4.7 kΩ resistor which matched the original schematic). R205 should also be 220 kΩ.

For your convenience, I've attached a Rev. 0 copy of my digitized schematic that I created when restoring my 46-480. It depicts the exact original wiring. I will also attach my Rev. 1 schematic, which shows how I modified the power supply for safety and captures any other modifications (i.e., changing C101 from a 20 µF to a 22 µF capacitor, due to commonly available values in today's electronics market).
