The changer appears to be a single speed type - 78 rpm? The rubber portion of the idler wheel is probably glazed slick which does not help. As for a replacement spring to provide tension against the inside of the turntable platter, McMaster Carr is a good source. Perhaps someone can tell us the size of the original coil spring OD and also the AWG of the wire used to make the coil. That will help you duplicate the original spring. It is possible that someone may even have reproduction springs and/or idler wheels or rebuilds idler wheels.
