BOM 100_a changed Q1..Q28 with available part #C2680385 (ZXMS6006SGTA) BACK TO OLD BOM! I made a mistake, the ZXMS6006SGTA is NOT compatible to ZXMS6005DGTA as it has the cooling fan to Source and not to Drain. :-( As a workaround you can lift the cooling fan from the PCB so that it has no contact anymore.
