I'm thinking the green tube is also a 'modification,' especially since the dial face is brown and is unlikely to be enhanced by the green light. Tube-wise, the Mighty 190 is an 8-tube set, numbered and marked on the schematic as follows:
1232 R.F.
7J7 Det.-Osc.
7B7 I.F.
7A6 2nd Det. A.V.C.
7C6 1st Audio
41 Output (two on the chassis)
84 Rect.
Aside from having only briefly had an introduction to radio theory for a week back in college, the terminology has loooooong slipped my mind (I majored in Marine Transportation, not Electronics).
