no transformer will come with banana plugs - just terminals that you
solder your wires to. you'll need to know what size plug Dupla is using
(i'm betting metric), as they come in several sizes. a local electronics
supplier will be able to order whatever you need (_not_ radio shaft!)

you need to take a good look at what is involved in building your own
power supply - it ain't simple, and you should know what you're doing.

you should fuse both the AC and DC side of the power supply. GFI is
always a GOOD idea when building an electronic device to be used around

some of your questions lead me to believe that you may not have had much
experience in electronic construction. please forgive me if this is an
incorrect assumption. 

putting together anything that is designed to plug into household AC is
potentially _deadly_, and should be approached with caution. if you've
never built a DC power supply before, you'll need to bone up on basic
electronic construction techniques.

a 24V DC power supply is not all that complicated, but care must be
taken in it's design and construction.

sorry to rant, but the FAQ (even though it says "if you don't know what
you're doing, get help") does make this sound like a "simple" project.
