Thank you Chriostopher, that's very kind of you. The good news is I have
managed to contact someone else who owns one of these boxes and have
asked them to forward me details of their power supply. If it turns out
to be something that's not available off the peg I may still need to
build a power supply for it but that should at least remove the
guesswork. I will drop you a mail off list if that turns out to be the case.

Thanks again,

Roger.
