1930's DeForest 569 Mercury Vapor Rectifier

I think this is more of a product announcement rather than an advertisement. The tube structure is very interesting. I'll have to keep a look out for the 569.

  1. Do you have any idea what the cleanup bill would be if one of these things went off hot in your house? Along with the hot Hg vapors attacking and destroying any modern electronics in the vicinity, you're probably going to lose the carpet and wallcoverings in the room, and insurance may not pay:check your policy carefully.

    Fooling with mercury anything is plain dumb. Yeah, they look cool powered up. So does xenon, and it's an inert noble gas. You could build a rectifier out of hydrogen thyratrons too, those are also safe, unless they have a radioactive component.
