The CRT's I had in mind are all actually shorter than the 6E5 eye tube,Ira.

Re: [neonixie-l] Re: OT: Do any long-life magic eye tubes exist ?
Thanks everyone for the responses. I purchased two 6AF6G tubes, and because of the way my big clock was designed, I believe I can get fine-grained control of the magic-eye tube from my NMOS drivers without changing the PCB (just a few component and cabling changes). I will attempt to make a replacement module with green neon bulbs that I can swap-out with the 6AF6G. They wont be pin-compatible with eachother, but at the connector where they plug into my clock PCB, they will be interchangeable. And since I use an FPGA for the clock logic, it's easy to support both by flipping a DIP switch. -- You received this message because you are subscribed to the Google Groups neonixie-l group.
