Title: The Noble Neon Post by: WA4WAX on November 22, 2015, 03:27:32 PM Lots of ideas for those bulbs! Page 21.
Have fun. http://www.americanradiohistory.com/Archive-Elementary-Electronics/1960/Elementary-Electronics-1965-Fall.pdf Title: Re: The Noble Neon Post by: MikeKE0ZUinkcmo on November 22, 2015, 11:11:26 PM Fifty plus years ago I worked for an electronic organ manufacturer. They used Ne-2's by the thousands for their oscillators and frequency dividers.
They burnt in the lamps for 5 days. Been a while but as I remember it was about a 30 foot long wall, with maybe 12 rows of vertical pairs of clips, spaced every inch or so along the entire length of that wall, about 4500 bulbs at a crack as I recall. The bulbs were then harvested according to their "firing" voltage. Don't remember the voltage increments or the entire range of voltages, but there were several different grades. The bulbs were then used in pairs of the same grade. Interesting little devices. Here is a little more information, maybe even more than you want. ;D http://www.tubebooks.org/tubedata/glowlamp.pdf Title: Re: The Noble Neon Post by: DMOD on November 23, 2015, 12:24:33 PM I open the link and what do I see, 2 Layfayette Walky-Talkees looking back at me. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
I had a pair of those for channel 14 and would go up on the 3rd floor roof of the flat and talk to everyone for about 3 miles around. When the one WT got low on Battry power I would switch to the other. Of course, the final circuitry wasn't stock. ;D Phil - AC0OB |
