I have a 2001 Caldera Geneva Utopia serious spa, and the board has gone out in it. I don't really want to replace it just yet (the actual hot tub, that is)......... Pool store says $1000.00 to replace and fix it. My husband is pretty handy,and could fix it himself, if I could get my hands on the right part. So............. anybody happen to know exactly what I would need? (Part number/links, etc)
