Whilst inspecting my handy work very closely after completing my SP-14 build I noticed that the heatsink that the LD1084V voltage regulator is attached to on the left channel is in contact with a track on the PCB topside. This track connects with the adjust leg of the regulator. The input leg of the regulator is connected to the heatsink via its metal tab. This would not be a problem unless the heatsink has a chip or scratch in the coating exposing bare metal on the base in contact with the PCB track. This would cause a short! To be on the safe side I inserted a piece of insulation between heatsink and board before firing the amplifier up. Filing the overlapping bit of heatsink off would be another option.
Roy and others may already be aware of this and I have got it wrong and there is no issue, so please put me right if I have.
My SP-14 sounds very good by the way!
