While a very late reply the issue of the bottom green LED coming on with bargraphs is offset on the TL072 used in the rectifier. Simply swapping it with one from somewhere else in the desk may well fix it. The offset tolerance is close to the level that the bottom LED responds. The chip is not actually faulty.
