Hello! I have the problem with PM3070. I have no the schematic and the PCB drawing from A3 block XYZ-Amplifier UNIT (A3). Can I ask You, who can help me to repair that board? Unfortunately I have no the Service manual for PM3070. I have full service manual for digital PM3375 series, but that board is different. I will be very grateful for any help. Regards, Sylwester Lazar
