In the BOM for the Dual SVF board, it mentions in note 1 that the SSM chips can operate in ‘Class A or AB’ modes, according to whether resistors R37 and 38 are installed. Can someone explain the difference in output sound between A and AB modes?
I’ve had a look at the SSM datasheet. Various graphs look quite different for the two modes, but I don’t really have any idea how that translates to differences in the resulting sound, so I’m afraid I’m a bit none-the-wiser
I notice in the example photo of a completed SVF board, the resistors are not installed. Maybe I should socket them, so I can decide which I like best…
