Hello,
I need an isolation transformer for my tube amp project and I wonder if I can use or convert my ballast as one. I have seen tutorial on how to use ballast as isolation transformer http://www.instructables.com/id/Ind...sh/step4/Preparing-the-Isolation-Transformer/
But my ballast is quite different, its closed and it has only 4 connections IN: common, phase, OUT: 400w, 250w.
I cant measure resistance between common and any other contact -it seems that it`s higher than 200Mohm (highest settings on my DMM),
resistances between other contacts (phase, 400w, 250w) is 9mOhm

Thank you for anwsers
