Hey everyone,
I have an Amiga 600 (rev 1.5). As soon as I bought the Amiga a month or so back I replaced all of the caps, I also replaced the Audio RCA connectors as well. Everything works perfectly, but I noticed an issue where the filter is always enabled on the right channel regardless of it being switched on or not (left channel still works as it should). The problem now is I have no idea if I caused this, or if its always been like that.
Turning the filter on or off makes no difference on the right channel, its like its always enabled.
I'm not an electronics expert, but not bad with a soldering iron and I'm kinda stuck as to what to try. I'm assuming this is going to be a bad capacitor, transistor or resistor - I can't see any issues with any traces and the board is in good condition.
I have looked at the rev 1.5 schematic and read somewhere that removing C331/C321 on the underside should bypass the filter but in this case doesn't seem to make any difference.
Any help at all appreciated :)
