I have recently acquired another pair of SL-1200s and have taken it apart to clean and service. I am having difficulties dating one of them. I have been to all the usual places for info on dating but none of them seem to help me on this occasion.
The serial number is MJ3K01D077 with SL-1200MK2-XGE written above it. The base has no provision for the extra metal bottom base I have seen on all other SL-1200s and SL-1210s and there is a larger diameter whole where the RCA and ground cables go. The power pack is also mounted differently to all other Mk2s I have seen with 4 screws holding it in place rather than 3.
The problem I have is that the serial number appears to be a later Mk2 but the base and top (plus internals) appear to be of the earlier spec. It doesn't make sense, the serial number sticker looks very untampered and original.
Any help would be greatly appreciated.
