hello i have two lister startomatic control boxes. one is in good shape and less complicated than the other as in does not have the large capacitor in the center. the other is in not such good shape but has the large capacitor in the center  and two extra metal fin type things. my question i obviously i want to use the good one. so are the diffrences in boxes just diffrent years of production and will either of them work? i have seen on google images there are two diffrent boxes.. many thanks Jason.
