Retained the same main PCB date but updated the display board and changed the audio amplification. Some units in this era introduced a slight "hiss" at zero volume.
Simplifies the board to reduce manufacturing labor, featuring only about 3 adjustment points and a different audio amplifier. xhdata d-808 schematic
connecting the two main boards, which must be handled carefully during disassembly. (like the ferrite rod upgrade) or component-level photos from community teardowns? XHDATA D-808 Radio Retained the same main PCB date but updated
