As I noted, the N/P means that the polarity is reversible by changing over two wires inside the set. Apart from the speaker connections, the only other lead fitted by the makers, IIRC, was the power supply one, which should include an in-line fuseholder with a(from memory) 5A fuse. An earth wire (the thick black one?) screwed directly to the chassis may have been fitted at some point. I do have the service manual somewhere, if more info. is needed. Be sure to check the polarity before applying power to the 108.
