    First off, new here, my first post.
    I'm starting to try to repair car audio amps, this is only my 3rd amp, and i'm stumpped.
    American graffitti S/X-2.10 amplifier.
    when hooked to power source, goes instantly into protect mode. no hesitation, no power light at all, just protect light.
    Testing the FETs with this method,
    http://www.bcae1.com/ampfail.htm
    1/2 way down the page.
    with the first test, i get the same exact reading on all 8 FETs, which is about 850 from the gate to drain, and 400 from gate to source.
    is it possible that all of these transistors are blown?
