Re: using an SS White x-ray transformer

Hi Terry,

Thanks for the info!  Very enlightening and has built up my confidence
working with this xformer again.  I'll let you know what happens and also if
I need any oil.

Initially I was also concerned about pcb's in the oil residue from when the
xformer was last used, but after performing a couple of "home" tests I am
confident none are present.  Just too many horror stories about seemingly
great bargain surplus transformers later turning out to have pcb's in the
oil.

Thanks again,

John
