Measured a bit more following the diagram which is definatly not my field of expertise.
On D1 the side described in the manual as cathode side is towards centre of the board, this side have 0.000V, but reading the datasheet of D1 it say that the ring denotes the cathode, meaning the cathode side would be AWAY from centre. This side measures 0.6V. Cheching some other places, i see that C2 have the full 9V on one side, and 0.6V on the other side.
Just to ask a stupid question: the entire board is DC?
