Soundcraftsmen schematics
The new 900X2 arrived today. I was surprised to see the front grille slots horizontal rather than vertical like the PR1800. Otherwise looks pretty much the same on the outside.
As I was unable to get any PR1800 or 900X2 schematics on any forums I bought some from this online source:

They have schematics for most of the soundcraftsmen line.
I actually bought the PR1800 schematic and they came with "PR1800; 900X2; Pro-Power 8" on them, so I didn't bother to buy the 900X2 schematics.
So it sounds like a Pro-Power 8 and 900X2 and PR1800 are all the same thing? rickedd46 has me confused, he describes an A900 as also the same 12 output transistors/channel but then describes it as 4-channel or 2 PM860 in 1 chassis, which would be only 6 output transistors per channel??? Something doesn't add up, even the power spec impedances are like unbridged, unless the A900 is like two 900X2 in 1 chassis?
Help please, Peak indicator light on?
unfortunately as of yesterday the right Peak indicator light on my "new" A400 is lit whenever I run the amp.
It lit up and low volume and has stayed on at low volume, even after shutting it down for the night and starting it back up the next day.
Does this mean there's something wrong with the actual output in terms of clipping or possibly that that light itself is defective? I can't hear any audible clipping/distortion?
