    Coilcraft T6 transformer confusion

    I have a Q4438-B variant of the T6 and was wondering can it be used with the sproggy PSU or does it have to be the Q4439-B version? If it can be used, is it wired in the same way or differently? cheers

    you will have to make some jumpers to connect the q4438-b in place of the q4339-b. check out the schematics on the two transformers
    q4339-b
    q4438-b

    wire as follows: (pin numbers)
    q4339-b <--> q4438-b
    2<----------> 3
    1<----------> 2
    7<----------> 10
    8<----------> 11
    6<----------> 9
    5<----------> 8

    so you would wire pin 3 on your transformer to the cricuit board hole that would normally be connected to pin 2 on the normal transformer
    look at this sheet to help you identify the pins:
    datasheet other than the modified wiring, it looks like it should work
