    I am trying to find a PSU with the following outputs (or as near as practical).
    It is for an ECHO Audio Fire 12. The PSU in it has failed and I can't find an
    exact replacment for it. UMEC do have similar, but don't have this exact model.
    The PSU about an inch high as it goes in the ECHO unit (which is 1U). But
    I would be happy for any recomendations of a PSU I can purchase that can
    supply these voltages?

    The spec states that it supplies the following.
    +18Vdc @ 0.3A
    +6.75Vdc @ 2A
    -18Vdc @ 0.3A

    Part number: UMEC UP0303S-0551

    Many thanks :)

    with this kind of audio gear that needs precisely regulated supply i wouldn't suggest you to make a DIY power supply. u could use lab power supplies, but that would be inconvenient to use for 3 different voltages.

    did u try fixing the old one?
