When I spoke to Scott, he said the startup sequence is the same as for a 7125. I have both and they definitely don't power on the same way. I have finally replaced the part Scott sent me, but the amp powers on the same way as before. It is almost like the caps need a little time to charge or a warmup period. The amp is in its box right now waiting for me to swap it with the 7125. I ran with it for about a month while the 7125 went back to the shop for a dead channel fix. I powered it on about 100 times and it acted the same way almost every time. No issues with the amp itself once it was on.
