Magic eye tube rebuilding
5 Attachment(s)
I have been wondering for a long time where to put the description about the rebuilding of the magic eye tube. After reflection, I decided that I would put in this section, at most the moderator will move elsewhere.
From the original magic eye, I only use the screen, clean it, and apply a new phosphor. The bulb, electrodes, cathode, zero grid and getter are new. For now, I gave up installing the control triode inside the lamp. This function is performed by a small mosfet mounted in a socket. |
That's pretty cool. If I were in your shoes I'd be tempted to phosphor it 3 different colors (green, yellow and red) along the indication scale in order of increasing input on the tube...

Cool ! Now all ya gotta do is make reproductions of the Zenith 6T5, and then watch the bushels of money come rolling in..... :thmbsp:
|
Even the 6U5/6E5 can be $40+ tubes in some places as NOS dries up.
|
I would have to have at least one bad 6T5 to see exactly its design.
|
I figured this would be a next step from CRT rebuilding. If it's possible to recoat the cathode and re-phosphor the target it should be doable. I believe the 6-pin types use a P1 phosphor, and the later 9-pin tubes probably the P31 phosphor, at least that's what I see based on the colors.

It's too bad an LED variation of a 6T5 or 6U5 can't be fabricated.

Hi to all,
Hi Titan 1a, Have a look at this color LCD magic eye substitute. Choice of colors, displays frequency & B+ voltage, if desired. No affiliation. https://www.radioelec.com/en/magic-e...4_384-834.html See it working here: https://drive.google.com/file/d/1-3-...m5I9mOdZk/view Best Regards jhalphen Paris/France |
Wow that's impressive. I never thought to rebuid one.

this is crazy. you may want to post over at Audiokarma, I bet people there would be interested. I myself have a stereo receiver (1961 Pilot 654) with a "Magic Eye" tube for a tuning meter.

Thank you :). Here I talk a little about my magic eye tubes. Since this is in Polish and you may not want to listen, scroll to the next link.

Interesting
This whole thread is very interesting.
If someone has a direct substitute of any kind for a 6u5 tube would be great. Any info on this in an English web site link or video would be helpful. |
