I reach down in my drawer of extra cables and stuff, connectors & computer cards & I bring up a 9v treansformer - isn't that what you want. Don't most of them have the same size fittings ? This doesn't seem like a rare item. Mine happenedto be a U.S. Robotiics modem cable, for a 56k baud modem. I'm sure you have a lot of those. What's special about yours ?

I get them for this product and i need hundreds of them ... not something that i can go to the junk pile for.  So, just for the record, now i get them from "All Electronics".

Or you could probably go to your local Radio Shack
been there, done that.  prob is we need a 9 volt and not a variable voltage one, and we need it in wholesale lots.
