The problem was solved by adding a resistor in parallel to the carbon track resistor. (I did not have the needed value at hand that's why I used two resistors) And now the AT works perfectly. Here is a photo of the two resistors in place: AT Resistors <http://groups.yahoo.com/group/yamahacs80/photos/album/1863574374/pic/10\ 5926260/view> Joachim [Non-text portions of this message have been removed]
