Is this the set you are referring to? I've got one in white. It wasn't too bad of a restoration. It's an adequate performer. I set mine next to my computer and used to watch the morning news on it but grew tired of the small screen.
Sams 336-14 covers it. It does have a power transformer. For the right price, they do seem to move an ebay, but I have seen some overpriced.
