I turned on a 3520A for about 10 years before I got my AB. I have always kept the control box on the headstock. Since the bed is stainless, the box won't stick there. The box on the banjo didn't work well either. I didn't have mine for a week before I replaced the 2 bolts set up. He doesn't make them that way any more.
