I have been searching google to purchase a 120v ac isolated transformer to stepdown the ac voltage to something usable.  Does anyone have a link to a website?  I plan I building my own benchtop ac/dc transformer.  I realize I can buy a manufactured one, but I want this to be a learning experience.  Thanks!

Hard to say because you haven't filled in your location.

Not sure what you mean. They are all manufactured unless you wind your own coil.

I'll have to fix that, but for now I live in Arizona.   I meant I would like to build my own benchtop AC to DC converter.  I would like to buy a isolated AC transformer and all the electronic components needed to build the AC to DC converter.  I can find all the components except the ac transformer.

If you don't need a large and expensive one you will probably have to make it your self. You can use two suitably sized step down transformers wired low to low and you would have created an isolated, current limited,  ~120v source.

You have also not communicated the intended scope of your project properly.
Power requirements?
Why would you strictly need a 120v-120v Isolated transformer?

If indeed that is what you need. It's hard to tell from what you have presented.

By design, transformers are isolated. They are electromagnetically coupled.

So I guess I am not really sure what you are asking for.

what exactly is your learning objective?

I did a benchtop power supply project like 30 years ago and I can't imagine that will have the same learning value nowadays.
