Hi Folks-
For those of you with x-ray transformers, I need some simple info: First, my unit was made in 1985. How likely is it to have PCB's? Secondly, it has primary ratings of 230 V at up to 120 A. Secondary voltage is 67.5 kV per side for a total of 135 kV. Is it OK to have a periodic arc now and then (I mean in case of accident?) Can I pull an arc to see if the thing works, without worrying about a blown tranny? It also has a bridge rectifier in it that doesn't look too beefy, but then again the current is very low. Can the bridge handle a arced output?

Secondly, if you live near northeast NC, you may be able to find a transformer from Jim Wells, whose company is Merry X-ray and is located in Wake Forest, NC. He mentioned he had a few extras around, though most were three-phase. He gave me a super deal (super= $100) and in addition he was very knowledgeable about the equipment and helpful getting it loaded up.
