Based on your description, a preamp failure seems likely. If you have
any test equipment (say a voltmeter) try to measure any AC output from
the preamp line out to "amp in" plugs. If there is output, the amp is
bad. If no output, that more or less confirms a bad preamp, but check
the continuity of the preamp to amp cables.
