Wow this is cool. Some questions:
I suppose I can create 3 secondaries that I need for my application.
What else do you think I need to buy and where (I hope they are available in local h*me depot)?

To reduce a 250V to 15V you would have to open up the transformer and remove almost all the turns from the 250V winding. Then you will have a 15V winding with the SAME current rating as the old 250V winding.

When they say "add" to the 6.3V winding they don't literally mean to do that. The plan would be a add some turns to create a new 8.7 volt winding and then wire that in series with the existing 6.3V. These new turns can go over top of the finishing tape so it is very easy.

But why NOT buy a second transformers. A small 15V one is very inexpensive

Understood.
I am thinking can save some space by using 1 transformer
Thanks!
