Tubes that glow a lot? (Not audio specific)

[Destroyer OS]

I am hoping some people here will know. Please don’t say light bulbs, you’ll be wasting everyone’s time.

These do not need to be audio specific. I am just looking for tubes that glow, and preferably that do not go bad quickly while doing so.

Thank you

I don't have any specific advice, but I will say that it varies by manufacture even with in a given tube family. So just because someone says, say "6SN7", it can come down to which 6SN7 (incidentally, I have some Tung Sol 6SN7 "mouse ears" which have two pins at the top that glow pretty well)

An OA3 has a nicer glow than most.

Any of those zero voltage regulator tubes have a nice glow. 0A2 0C3, etc etc

If you mean the heaters, what matters is the part that is inside where you cannot see. Some individual tubes have heaters sticking out farther than others, making them more visible. But that is individual tubes.

NIXIE tubes (and their Soviet equivalents) have a nice glow, produce zero heat (being cold cathode) and last a very long time.

You may want to look for tubes from the 1920ies, when cathodes or filaments still weren't coated.

Best regards!

Loving the info. I was pretty sure I would get some quality info here.

I remember one of the many radios i had growing up had the magic eye. My dad was a ham operator and I was always messing around with radios and antennas.

Yes, any tube that has to show you something looks quite amazing. Here's a link to the Japanese (made by Toyo) 6G-E12A, an indicator with two independent sections and, note, a very unusual rectangular screen.

Best regsrds!
