C-H,
That transformer unit on the right looks vaguely familiar, I think it may have been built by ABB Systems, if this is any help.
I checked up on a travel guide for Tuvalu and it said that the power supply is 240VAC 60Hz, there was also a website on the page
www.tuvalu.tv , so you may find something there, there's even a Forum there!. [Linked Image]
