Yeah, you definitely need a good transformer. It may be cheaper for you to build your own transformer. If you do build your own Isolation Transformer, I hope you write an article about it so we can see it!

I know about the safety transformer why I wanted to buy one Robert. Maybe I can build one. I need good powerful transformer(s) for that but they are very pricey. Recently I had a 2KVA transformer that was 230VAC in and 110VAC out. I gave it away because I need at least 2 identical ones to make a 230VAC to 230VAC safety transformer.The 2KVA transformer was too heavy anyway.

Thanks Robert. I normally use a 24 Volt light bulb in series to bring up the power supply.
