BTW, it usually took a few hundred mA to burn the short. On Sunday, February 12, 2023 at 9:31:13 PM UTC-8 gregebert wrote: > I investigated internal shorts with IN-1 tubes about 10 years ago, and > never use them because of that. > I never had anode shorts, but I had multiple cathode-to-cathode

I investigated internal shorts with IN-1 tubes about 10 years ago, and never use them because of that. I never had anode shorts, but I had multiple cathode-to-cathode shorts, resulting in more than 1 numeral being on at the same time, which will cause more current and will burn a small-wattage a

RE: [neonixie-l] What is this tube ?

They are NO magic eyes, but VFD display’s like every other VFD 7-segment display the indication is by steps every dot (or triangle) is on or off The Russians also had things like this, but with round dots and about the length of a IN9. Remarkable is the “zero” level display with up-down indic

I dont think it's a 6E2... the tubes in the photo have distinct bargraph segments, I'm pretty sure it's a VFD. On Sun, Feb 12, 2023, 2:27 PM Tony Adams wrote: > 6E2 'magic eye' tubes driven to produce a colon?. Very neat but power > hungry and short lived I'd expect. > > On Sun, Feb 12, 2023 at

6E2 'magic eye' tubes driven to produce a colon?. Very neat but power hungry and short lived I'd expect. On Sun, Feb 12, 2023 at 10:44 AM Benoit Tourret wrote: > Ok ok... > It doesn't seems to be a regular item... > > It must surely be Chinese, the lack of clues and evidence brings us there > wi
