    Replacement thermistor values

    Hi, I have a behringer B205D monitor that powers up but has no sound output. I've gone inside and discovered what I believe to be a blown thermistor. It looks to be a chinese one, green disc with no values on it. The behringer schematic has it as R1 with a value of 10. Am I correct in thinking that this is 10ohm and if so what can I safely replace it with so get the monitor working again.

    Please post the schematic you mention.

    And, what does "powers up" exactly mean?
    Do any lights come on?
    Do you hear any pop/click/hiss?
    Any other sign of life?

    R1 is indeed a NTC thermistor with a value of 10 ohms.
    It is used to limit inrush current at startup of the unit.
