I think some friends have seen the previous post because he was very confused. I think I will reorganize and send it to him. This is a very old DAC, with a price of $200 per unit back then. Because it is the first generation chip for recording magnetic tapes. So he is very valuable. He works great and can recall warm vintage sounds. You can purchase PCB boards and ship them from China. If you are a friend of the European Union. Please provide the IOSS number, which consists of IM and 10 digits. The mailing time is about 10 days. All PCBs consist of four parts: audio input board, format conversion board, DAC decoding board, and power board. You can play app content through a Bluetooth chip (purchased in China, manufactured in Shenzhen), or use CS8412 coaxial to play CD content. COMBO384 can also be used to connect to a computer for playback, and there is also an external input IIS interface for connecting to Philips turntable playback. I will provide Taobao product connections. You can use Taobao's overseas warehouse to purchase. If you need assembly instructions and BOM list, please send an email application: 410746700@qq.com
