Got it! A screwdriver blade placed UNDER the bottom center pried it out; the fuse was blown. The replacement failed immediately.

I am dismayed by all the reports of failed power supplies in Meridian gear. It's an old unit and out of warranty. I guess

I'll give Marc Koval a call.

Thanks to all for your help.
