Thanks guys for all the ideas. Here is what is happening now/update. First I power up the pre first. The amp was boxed for six months or so. I have had the amp in stand by mode for 3 days now and the very faint hum i heard is gone and when I power up the amp is stays on 99% of the time. If it does pop off and I turn the amp back on it stays on and sounds wonderful. Maybe I will call Manley and see what they have to say. Thanks again
