Hi!
I have a non working multimega,the system doesn't start,however the CD rom unit works only the with batteries so I think that the lens is ok.
In my opinion the system was connected with a wrong AC adaptor.
I suppose that there is a problem on the AC board with B1267 transistor,does anyone know where can I buy another one?

2sb553 came up an alternative while I was googling.. You'd probably get away with most power transistors, I've had fairly good luck using whatever I have on scrap boards as far as replacing transistors.. Just gotta make sure it's the right type. (pnp/npn)
