Genuine ALPS switch used in Sansui G8000 and G9000 receivers, it is the same as switch for:
Speakers system A, Speakers system B, Turnover, Tone, Audio Muting, FM Muting, Mode, Dolby FM, FM Auto and FM IF Band.
In G22000 and G33000 they could replace all switches for audio functions like Speakers system A, Speakers system B, Turnover, Tone, Audio Muting, maybe for Tuner functions too, but now, I cant remember. For sure they are not compatibile for switches TAPE COPY and TAPE MONITOR in G22000/33000 receivers.
This is a picture of TONE SWITCH BOARD from one G9000
As you see, they are the same!
