Make TDA1540 Tube output DAC

The love for TDA1540 belongs to everyone. Today we can still use the Philips LHH2000 and hear its warm sound. However, it is very difficult to obtain the output transformer of LHH2000. I think only through TUBE output can I find the feeling of LHH2000. I think I will share with him. You can also purchase him.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 five parts: audio input board, format conversion board, DAC decoding board, HV power 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
