type in "isotap wp" as a search on ebay and you'll get a variety of VIZ Isotap isolation transformers. However, I bought mine from Valutronics since I was new to this sport and wanted to be certain my isolation transformer was working properly. They check it out before shipping. They currently have a 25A model for sale for $29. https://www.valuetronics.com/detail/Used...qt-VLSQORM (I have no relationship with ValueTronics).
