I looked up the tda1308, and it's actually eol'd by the manufacturer, which is weird. I found an equivalent, the ts482, and drew this based off of the datasheet. I don't want to wait for anything to come in from china, so I'll just buy a breakout board and the get the components on mouser. I'm thinking it's class AB, so I shouldn't have to worry about board layout. I think i'd have to tinker with the complete board to get the volume pots connected anyway. Would I have to worry about the feedback resistors conflicting with the volume pot values?
