Re: X-ray transformer modifications

I haven't had any problems with trapped air yet , but I'm also not operating it under a load or at the higher voltages it's capable of producing. There wasn't any benefit to leaving it out of oil for as long as I did. I could have easily lowered back into the oil when I wasn't working on it. That's ...
