    Hello everyone,
    I am hoping that you may be able to help me.
    I have an ADC SoundShaper 3 eq that the power supply transformer is dead. I am trying to fix this for a friend but not quite sure where to source this part. I have a schematic of the power supply section and I am hoping someone with greater knowledge than I can point me in the right direction.
    I have checked the old transformer with a meter and there is no output.[​IMG]

    Thanks for any help.
    Rick

    Can you post a photo of the transformer with a scale to show dimensions?
    Is there room for two transformers?
    Looks like you need two windings, 85VAC and 36VAC.

    Your not likely to find one except from the company that made the amplifier. It is a dual transformer 18 volt center tapped and 42 volt center tapped.
    Transformers usually don't go bad since they are just wire. Are you sure you have voltage at it's input?

    Definitely voltage going in. I have looked for a used or new one, no luck. There is actually room in the case.
    I will try to take a pic for you.
    Here is the part # on it. P100721, TKP0151-17.

    This is actually an eq. Fairly low power consumption. I will take a look and see.
