Built PCB assembled on to Akasa AK-860 heatsink (not supplied with kit), click for larger view.
Please note that this new module will only perform to expectation when installed on a purpose designed PCB, some builders are using a PCB previously designed for the bipolar modules (M57762 etc.). Users of these PCBs may find low output power or in extreme cases instability and device failure.
Although advocated elsewhere on the net I wouldn't recommend filing the back of the module flat (its manufactured with a depression), this can lead to the substrate inside the module cracking.
