Opera Consonance Calaf Mk2 arc sounds after pluging in while power button was on

I have a consonance calaf mk2 that smells like burnt electronics and it makes small popping/arc sounds when i turn it on. It started after i plugged the power cord into the wall with the power button set to on. The fuse in my house blew, and when turning it on again the amp startes having these issues. The amp works just fine, but i dont want to use it before i Get this fixed. Anyone experienced this before?

Typical over-done chinese design, designed to impress, yet poor build quality resulting in reliability issues.
And nothing online about service information either - again, built to impress (heavy) but from what I can tell, it doesn't have a spark-snubber capacitor across the power switch, or likely some form of slow turn-on either.
Without service info, you'll only get speculation replies, unless someone magically has a schematic on that thing.
 
Size and superficiality reigns as strong ways to market and sell something.
The well-known phrase of "bigger is better", along with eye-dazzling appearence is something used by those chinese in hopes of finding someone gullible enough to open their wallets.
And after the sale, those same companies usually can't be bothered with providing help.
