Thanks for this information ( I Did not know this about Toroid transformers )

I have only seen this type of transformer a few times in a few devices I have seen them at some electronic surplus supply stores online I have been tempted a few times in the past to buy some but not have any experience using them I have not bought any of them

I will read about this type of transformers from the website links that you provide

Thanks again for information
