I suppose to obtain the stereo two SN76489 is needed. One for left and another for right for the same channel.
I think, channel 1 of the first SN76489 is dedicated to left channel and channel 1 of the second sn76489 is dedicated to right and so on... To play sound on left and right (center) we need to use both SN76489
On this video we clearly see 8 channels but grouped by two for stereo. It' a wierd implementation of the stereo. Using one chip per channels and wasting 4 voices.
