    Marantz 2325 2SA747 - low breakdown voltage

    I am working on the amp boards for a 2325 and checking the outputs I found one of them (A747) testing a breakdown voltage of 167V, whereas all others test 247V or so. Is that a sign that I should replace the whole set? Would replacing just the A747 with another pulled from a working unit be OK?
