Hi,

I know this is a wierd questions, but this tube group is wierd. I want to
build a tube nightlight. I need a suggestion for a tube type that is cool
(lots of wierd glass or form factor) and when powered only by it's filament
will provide a great glow. I think these will make great artistic giveaways
for fellow nerds and geeks.

what tube type?

Gerry

I saw this done with voltage regulators, in a popular electronics article
within the last 10 years or so.
Try an 0D3G, or similar. I'm not sure if it will give off useful light, but
it's a neat purple glow.

Get yourself an old tungar bulb. They look way cool, and they're pretty
much useless for anything else, so you won't be wasting a precious
thoriated tungsten tube as a nightlight.

Cheers,
Fred

0A3 (neon)
6AS7 (two big cathodes)
12B4 (one small)
Most thoriated tungsten tubes
6L6GC if you want to send it operating voltages (these can be AC);
blue glow.
Eye tubes (6U5, all those British types, etc.)

Thankyou, max, ronald, fred, tim:

Thanks for the great suggestions. i was thinking along the lines you were,
but not sure that i remembered which tubes glow the best! The eye tube idea
is something i want to play with, i went to mendelson's surplus in dayton
just yesterday in search of these sorts of tubes (they have a great tube
room) but the eye tubes of every sort of type number have been snapped up.
but i will play with the other types in search of the tube art geek
nightlight.

thankyou for the great suggestions!

I think these are transmitter tubes with tungsten filaments...

Hello, Gerry, Hullo, FellowRATs(TM)

fear not, this isn't weird at all. Try to obtain an NOS Russian
GU81-M, Which has a plate as big as a fist, and no mica supports
obstructing the filament's glow. I use one myself as a nightlamp, it
takes 10 Amps @ 12 Volts if you use the filaments in series, you're
also free to let it run on 6 Volts 20 Amps if you wish to have a kind
of 'hot tail' heater (those conductor wires)additionally.

(c;

(^^- I stole this, but don't know who from, it is _very_ cute!)

Those BBC triodes mentioned in another post are also nice, I have two
of those T50-1 's, but I think they are too precious to be misused in
that way. Gonna build a big Triode-PP around them.

regards
Sebastian

One of them is for sure, but I think the one that looks like a bong is a
"tungar lamp" (rectifier tube).
