Not good, I pulled the PSU out tested the capacitors they read 45v I discharged them with a light bulb setup. Then tested unplugged the capacitors from the recitifer and turned it back on and tested the output of the transformer diddly squat. There's 240v going in but nothing coming out.
Well that shows the caps are OK.
Now check to see if you have continuity between each winding pair on the transformer after you have disconnected it fro the rectifier
I doubt the AM882 has blown the transformer. Did you have it working at one time or is this the first time you powered it up
