Dear all,

I've just bought an LC3 case 2nd hand and there are a couple of issues that I need help with.

Firstly one of the 16 way BUS board headers has one of the -12V pins missing. It looks like the two vertical rows on each header are duplicates of each other, so I assume the remaining pin will give -12v if I plug a module's ribbon cable to it Or should I take it apart, and solder a new 16 way header strip in

Secondly the external PSU brick's on off switch seems to be faulty, and not always creating an ON connection–  I wondered where I can buy a replacement  

Thanks in advance,

Neal
