Hi I have a Supercap which I bought years ago. Checking the back recently I noticed that the serial number isn’t there and it is different to the one in the box when it was supplied which is for a NAC52PS
Any explanations.
I wondered if the Supercap may have been swapped into a PS sleeve.
Yugster, the usual reason for units with no serial number is that it is probably a staff build item. Historically staff could build units in the factory, but these were not given serial numbers.
I have a Supercap that was upgraded from a 52PS. The rear panel should have a serial number and the box on mine was updated to the new Supercap serial.
Yes, if there’s no obvious serial number then it’s either a Staff build item, or the serial number was removed at some point (although, if so, there’s usually another one hidden inside somewhere if the unit is internally disassembled).
Yes, a “staff build” item is something that was built by a member of staff. Naim offer and indeed encourage staff to build their own kit for use at home; not only does it engender a better understanding of the equipment, but it also enables staff to purchase the kit for little more than the cost of the parts plus cost of test and some overhead. Build could take place outside of normal working hours.
For some of us, like me, who wouldn’t really trust their own soldering skills, we would go and ask some of the best PCB workers and wirers to build a bit of kit on our behalf, and in return we would usually provide gifts (alcoholic variety usually very popular).
