    Hi,

    You will have to use an ohmmeter to check resistors. But, unless they show damage (discoloration or split body), it's much more likely something else is bad.

    You need to verify that all the power supply voltages are present - if you know what they are. Being able to inject a signal and follow it through with an oscilloscope would be helpful, too. Without a schematic, this can be quite a challenge.

    Depending on the brand and model it may have a safety cutout that kills power if it detects the slightest problem in the amplifier.

    You may be able to order a schematic from the manufacturer.

    If its not the fuse, or the Power supply.... odds on bet that its the Output devices......
    Might be cheaper in the long run to take it that 50 miles, and put up with the long wait.
