Thread: Mercury vapor tubes

  1. #1

    Default Mercury vapor tubes

    I am planning on firing up my old Elmac AF 67. I hope to use it for AM and CW. I have an old home brew power supply; however I hope to build a new one using mercury vapor rectifiers. Call me weird, but I remember the first ham station equipment I saw, 60+ years ago. The glow from various cabinets, which changed with modulation, was very impressive. I would like to get something resembling that in my shack. --- Question: Any idea which tubes would give me the biggest "show” for this setup? Where is the best source for them? -- Thanks for any ideas.

    Well, I thought about a pair of 866A Mercury Vapor Tubes, then the 872s and 83 tube which is a full wave bridge but I think the 866A tubes would present a warm glow to your shack.

    Purchasing 866A tubes from Tubr World https://www.tubeworld.com/866a.htm

    Or

    eBay 866A Vacuum tubes http://www.ebay.com/sch/i.html?_from...=866A&_sacat=0
