    The new heatsink on the back of the ADC board will lower the ADC chip temperature enough for it to operate in the safe range of temperature. I have modified my 6600 several months ago as per the instructions and I have not had problems. Dave wo2x

    The back plain of the ADC board is a cooling plain, it has been discovered that the cooling from the back has a much better cooling effect then on the chip itself. This is in part that the chip has a plastic coating on it that hinders cooling. If they had realized this from the designe stage they would have done it this way from the start.

    Un like many kinds of boards, the boards used in the flex have cooling back plans to cool components. As I mentioned, the 6500 needs no heat sinks on the ADC because the back plane cools the ADC more then It needs.
