You have a Code 122 version. Have not seen the Riders, but it sounds like it's not correct. R100 (as called out in the Philco service Bulletin PR-1135 for Code 121 and Bulletin PR-1298 for the 122) is an 80 ohm candohm unit (filament string ballast). The 46-200 Code 121 did NOT have a 14B6 in it.

The Model 48-200 has that tube lineup in the Rider's you are referring to. There also is no R100 filament string ballast resistor in the 48-200 because the IF tube has a 14 volt filament (14A7) instead of the 6.3 volt (7B7), the difference which R100 makes up.

Riders got it mixed up. There's the confusion.
