I have 5 of these & they look like big light bulbs with wire coming out the top of the globe. I got them from an old movie theater projector's rectifier. I was curious if there's a way to test these, since there's no large screw in jack that big on my tube tester. All of them have the little coil of wire still in tact inside so I guess that's a good sign. They look like when fired up they could heat a small room. Anyone familiar? Thanks!
