ok I replaced the nte130's and put it back together and... well not to much. It runs now pulling very little current, but it seems the output board is not amplifying as I have signal but not loud like only the preamp or drivers working, is not getting hot anymore but I feel that is not pulling any draw. On the scope I have signal in pin 1 of the Molex but on the differential, I see half the wave which may be what the differential is supposed to do and then send its half to the plus or minus side. It seems to be doing that, but the main drivers and amps are not turning on???? will take some more measurements soon on this eternal restoration.
