Hi Peter,

Ok, these are the Amglo neon lamps that interest me! Here?s my observation?

As M?nico suggested, this is a neon lamp that was made for indicator use. This same lamp was used in the amplifier circuits of some 1930s jukeboxes. The lamps were used as bass and treble indicators. This fact leads me to believe that the length of the glow discharge can be easily controlled, maybe by varying the current fed to the tube? I?m sure they found uses in other types of electrical equipment as well. As for when your mystery tube was made, if you?re curious, I would guess around 1937 based on the scraps of information I?ve gathered.

If you come across any more please keep me in mind! I may have some interesting flash tubes to trade

Tim,

Slightly off-topic, but I do have a long thin neon "bar-graph" tube from Russia. It's sitting on my workbench waiting for a rainy day (here in Kelly-Forn-Ia we can count those on our fingers).

Anyway, I believe it is a glow column who's height is controlled by the applied voltage. It's glass and about 150mm long by 12mm diameter, with wire ends (two or three IIRC).

I have not seen the "Juke Box" displays you cite, any PIX?

Comments Welcome!

"DRUGS"? LOL!

Yep, I know about Henninger?s neon alphabet tubes but I?ve never seen any in the flesh before either. You?re right though ? your mystery tube could be a letter tube that served a dual purpose, maybe. Here?s evidence of a pair of ?I? tubes used in that jukebox amp I mentioned before, along with a picture of the tubes for comparison to yours. BTW, this amplifier is from a 1937 Mills Studio jukebox:

Here's the chassis, Amglo tubes are highlighted:

and the Amglo tubes?

Comments welcome?

Tim,

Thanks for posting these PIX. Another clue drops into place. My single tube is identical to your PIX. Perhaps I don't have an alphabet tube after all? I got the Pat numbers of that tube, BTW.

This would explain why no other letter tubes have been found recently. Could it be that Amglo failed to market the sign tubes, and someone found a secondary use for the 'eye' tube as an indicator?

I wonder if there was a patent for this application? Your PIX shows a standard tuning eye tube alongside, so this must have been a show piece of current (ie 1937) electronics construction.

I have not tried to vary the supply to mine, just lit it up to confirm it was good. (Note to M?nico - I can't get any of the Amglo open spiral tubes to ionize. It's probably beyond my present test voltages which are geared to Nixie tubes).

Comments Welcome!

M?nico, could you please send me your address. Recently I picked up a few more ?open spiral? Amglo flash tubes and would be happy to mail you one but I just need your address. Please email privately, my email address can be found here:

It looks extremely cool!
I will email you tonight,
Thank you very much Tim!.
