>the preamps get powered up last, after the power amps are up and running. the "hum" definitely comes from the power amp, because you can hear it when everything else is off.<You might want to power up the pre-amps first, then if they make any clicks, pops, snaps or thumps (especially as they age) they won't be amplified and passed on to the loudspeakers.
