Live from Denmark : ETF 2015 - Part 14


Today I took a couple more shots of Frank Blöhbaums line stage which uses the most unusual and beautiful voltage stabiliser tubes.

What an eerie glow!

It is fascinating to watch the glow move along the grid as the tube is in action:

Another clip from a different angle:

Thanks to Frank for bringing this beauty!

Best regards

  2. Wow, I have never seen a voltage stabiliser tube in action, it is amazing!
    Any chance you are going use one of these beauties in a future design?

    1. Hi!
      I would first need to find some of these before I can build something with them.
