A disassembled Marantz CD 73 on a very messy bench. This is also based on the classic Philips CD 100 / 104 / 204 / 304 mechanism and board-set. Marantz' version of the servo board can be seen in the middle, to the right there's the decoder/analog board with dual ceramic TDA 1540s and a crazy daughter-board containing Sony decoder-chips(!). Very unusual that Philips (who owned Marantz at that point in time) would use Sony chips. On the left, there is an insane sled mechanism that can eject the whole CDM-0 transport from the case to load a CD.
