HELP Aleph 5 is burned?

I was making some tests because a ground loop with computer as source.
I was testing different power cables on the Aleph with different multi outlet plug strip, all used and without problems, but with different characteristics.
A typical test: power on, 10 seconds of music, power off, change the cable or the outlet, power on...etc.

I made it about 5, 6 times. Last time that I powered on I heard a kind of "snap", burn smell for few seconds and the Aleph since that moment is mute.
Panic!
I watched the fuse on the input, but is good.

Please, somebody have suggestions?
Thanks in advance

...well, Aleph 5 have 2 separate channels and the common power input. Well being it mute in both channels I think that the problem could be in the power input, I don't think is in the 2 different channels, or at least is more difficult that something burned in both channels.

You are right, I am sorry.
2 powamps that I loved burned in 2 months and I'm a little depressed
...I'm tired, I'm beginning think to change hobbie, something more "solid".

Thanks for your reply. With the friend who assembled it we found the problem: he tell is a diode and capacitors problem.

And thanks to mr Pass who shared with this community the project: a great man and a rare example of gentleman.
