### ⭐⭐⭐⭐ Good, for what it is
*by P***8 on August 15, 2022*

I inherited one of those inexpensive record players. It was damaged because they hooked up the wrong power supply and fried the existing board. I used this board to replace the amplifier, and it worked. I'm surprised honestly by how well it actually works. We're talking 3 watt speakers, so it's only for personal listening but it worked out and made the record player at least able to play records again.
