Review on 🔊 High-Quality Bluetooth 5.0 Power Amplifier 2 Channel Stereo Mini Hi-Fi Integrated Amp 2.0 - 50W x 2 USB Wireless Audio Receiver for Home Speakers & Headphones - Douk Audio Tone (Silver) by Stacy Preddi

PSU is rubbish. DO NOT USE! The cap says "LITE-ON Model: EADP-75GB A". The plastic case could not be closed due to the PCB design. See Figure 1. Very thin PRIMARY wires, barely connected (and partially exposed)! See Figure 2. The extra secondary wires are cut off and simply left hanging in the case. See Figure 3. The non-working power LED is only connected with a (bare) wire and hangs in the housing. See picture 4. The worst thing is that the separation of primary and secondary is completely eliminated by a metal radiator! The only thing separating the output from the mains voltage is a very thin piece of plastic insulation. See Figure 5. By the way, there are CE and UL marks on the power supply cover! The amp is excellent. Use your own reliable power source. (9-24VDC)
