The question about the A600 has been settled earlier in here, but I'd like to add some words. I extracted the previously stated numbers for the A600 filter from a schematics PDF that's circulating, which in turn actually contained A1200 Rev1d specs in the audio filter.
As luck would have it, I was just handed an A600 for fixing. And unsurprisingly by now, that A600 has the same filter as A500/2000, 100nF+390Ohms.
