    Can anyone identify Q5 on the PCB for me?

    I have a dead Squeezebox radio, something is dragging the PSU down.

    After quite a bit of diagnosis I think I have found that Q5 has
    failed, I'm just hoping that it is cause rather than effect.

    Q5 is a three terminal semiconductor of some sort, can anyone tell me
    the device ID or point me at somewhere that can tell me?

    I'd found that but hadn't read through to the next pages, in one of
    the later postings I found "I also had to replace Q5 (?) with marking
    "P3A" right above Q3. It is a PNP Transistor (DPLS320A). Mine was blown. "

    So it seems that it's a PNP transistor, I can get them from Mouser
    (among others) for ú0.33 so it's worth a try anyway.

    Thank you!
