Question for Marantz 22XX Receiver Owners

Does the Stereo indicator come on for multiple functions (Aux, Tape, Phono, etc., ie everything except AM), or just for FM (when a FM stereo station is tuned in)?
FM stereo only.
Can anyone else weigh in on this too? (Thx)

Does the Stereo indicator come on just for FM (stereo stations) or for other sources too on your 22XX Receiver?
FM..Stereo only and won't come on with weak stations also....
I have both a 2220b and 2265b. The stereo light only comes on when tuned to an fm stereo signal.
