To answer the questions:
The amp itself is not working. GoldenEar is sending a complementary re-placement.
Yes, the light on the amp flickered and went out after being plugged into the wall..
The amp is internal. Can’t take a look at the back.
I bought the Furman from Amazon. Easy return.
I’m going to plug the amps in the f…ing WALL.
Nothing has gone wrong with blown components from electricity in several decades living here. I’ll take my chances.
However, my electrician is looking into a surge protector for the electrical panel.
