This is the contents of the Douk Audio X1. What I'm sending is the parts in the first photo. It turns on, but no sound comes out at all. It's unknown what's broken. The vacuum tubes were lit, but Bluetooth didn't light up, and no sound came out. Please consider it for parts. I have a second-stage board with input terminals, and I have another one that is unused. Please note that the power button is not included. The speaker cable section at the rear was arranged in the product's original order. Please make your decision based on the photos. Due to it being junk, returns are not accepted. Shipping is included via Yu-Packet Plus.
