amp I bought 3 days ago not powering on - electrical engineer advice wanted

Consider taking it to George Meyer AV in LA.

They specialize in AV repair and did a great job replacing the capacitors in my power supply for a 35 year old Carver.

Hope that helps. 

yes, thank you @genomeip !

Well, since I'm being ignored I withdraw my questions, your Honor.

I ask because if the wires coming off the power switch are utilizing connectors as opposed to being soldered, even someone as mind boggling inept as you can change the power switch. 😀

Those things are really inexpensive and worth a try before you take a hundreds of dollars loss. Or not. 

Gosh, I hope my advice isn't too inept.

Wow, $800 for 3 days' fun.  That seems a bit too wild.

@parkergetdean 's amp sometimes powers up normally, and sometimes it gets stuck in protection mode. But either way, it always powers up, in the sense that it comes to life, some LEDs light up, etc. 

That almost certainly rules out the power switch, which is most likely doing its job just fine.
