I started to recap my pma-850 and noticed it has the ETC-281 board . This board is connected to the crosstalk control pots on the rear of the unit. The SM I have does not show this board . So there 2 versions of the 850 ? Excluding the 850II. I can't find any paperwork for the ETC-281 board . Anyone care to comment ? thanks
