    i want to make a transformer tester. that can drive normal adaptor transformers 60 hz and smps one at a few thousand herts. i have tried a couple of 555 timer circuits but non seem to work.
    can this be done with transistors.

    I would suggest you use your 555 to drive mosfets. If you are trying to drive a transformer with a 555 I would be surprised if it still works, the back EMF from the transformer has probably fried it.
