    I purchased a nonworking Miller Spectrum 375 plasma cutter off craigslist. After taking it apart I found a blown transistor, however I do not know how to find the correct replacement part. I have a copy of the schematic. I am looking for the values of:

    D13
    Q6
    D46

    I have attached the schematic, the circuit is on page 2 (Pilot Control)
    I am somewhat of an electronics rookie but have some basic knowledge.

    Thank you in advance.

    Here is a pic of the blown part.

    The D46 IN4746 is an 18V 1Watt zenner diode. Q6 is an IGBT but the number on the circuit doesnt come up & neither does D13 09249X. Pity there isnt more to read on the Q6 in the picture.
