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

You sure you don't want to try a shamanic purification rite?

It sure sounds like your amp has accumulated spiritual residue.

You must cleanse it so it may reconnect with the greater cosmic flow.

Or, you know, use a tech. Potato potahto...

It’s no longer “amp I bought 3 days ago…”

may be heed @thecarpathian advice. Call a priest. It needs either exorcism or a final prayer. Cheaper than the tech with a collection of nice cars.
 

no, I will not heed @thecarpathian advice @audphile1 

Not because it's bad but because his brain was exposed to too much Florida sun.

Update: my troubleshooting is shot. It doesn't turn on now when nothing is plugged on. All my hopes are in the Murietta tech baby!

If it ends up being the power switch you owe me a nickel.

I think the amp is out of order. You're out of order! This whole thread is out of order!!
