<p>chris<br />
guess there is still some trouble on C5 in the new docus, compared to the 2.1 pcb.<br />
square(+) down, round(-)up, it should be.<br />
or the input won't  work!<br />
i checked my board and C5(-) goes to the center lug of the input-pot. and all works.<br />
is there something wrong with the schematic?
