• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

ID this for me?

It a mercury vapor rectifier tube, but I don't know what type. Don't break it open. They're pretty efficient, but most of the transmitters, dielectric heaters, maybe x-ray machines etc that used them had them replaced with silicon very long ago because the mercury tubes needed a 15 minute warm up if the mercury vapor condensed. So it's basically a display item, more dangerous than most due to the toxic material. Being so long, it is higher voltage than most types which is why I added x-ray machine to the list.

What you have is a very high voltage, high vacuum rectifier type 5576. There is no mercury in it.
