19V 4.7A 90W Power Adapter Supply

i had some trouble sourcing an adapter of this spec. I'm happy fosi carries it.

The first one i had made a weird clicking sound. It didn't let the amp get enough power for a passive set of bookshelf speakers. The second works though!

I have 4 Fosi amps and they are powered on continuously and the power adapters are beginning to fail so appreciate being able to only purchase the power supply. The surprise was when it arrived it was not the exact replacement but I assume it’s the correct one because it has the word “Replacement” printed on the back.
