I used this output transformer (2 X 115V - 36V (that is, with 2 X 18V in series):

The reflected load is then 75 Ohm (in each half primary section), corresponding to the theoretical maximum power transfer.
For feedback I had manually added an auxiliary coil through the center of the toroidal transformer (about 100 turns); the actual output of this coil was 1/8 W.R.T. the 36V output, enough for the purpose.
For the input transformer I recommend something like this one:

If you wanted to create an industrial product the safety problems are the same as with old TV sets (nothing new).
