Here you can see my homemade "shielded" signal cable and the SureElectronics 4*100 heatsink. On the right is a small fan pointing at the location where the power protection diodes are (sort of). Also, you can see the holes in the case where the old SureElectronics 4*100 was mounted. The 41hz Amp9-basic is a much smaller PCB.
