I noticed in my player some low serials as well as what looks like added components (fixes / upgrades ?). For example there's a BAW62 diode over a capacitor on the CDM board. Another added on the servo board. And why were the two capacitors next to the crystal not already routed on the circuit board ? Did an earlier design work without them, and what their addition fixed ? And what are those serials ? One caught my attention: the yellow one with a hardwritten 114. Same type as the typewritten CD200A / 0003845. Could this mean a very early board, hence the added components ? I'm really curious. Photos are here. Also, if one can help me dismantle the unit to recap the boards that would be great. Power supply is already done. Also, I was amazed to see so many different screws, just like if someone dismantled the unit and lost most of them, replacing them with various types. Any ideas ?
