Is that the frequency reference in lower left in the 5th picture? Wow if that's the reference oscillator that's a big old school one for sure. Bill On Monday, June 7, 2021 at 6:32:01 AM UTC-7 martin martin wrote: > HP 5245L Nixie Tube Counter from Sandia Labs, Los Alamos, Manhattan > Project

I loved that movie btw "Bite The Bullet" with Gene Hackman , Candice Bergen , and James Coburn . I finally broke down and bought one tube I've never had befor

It's Paul Andrews I was referring to... I'm not at home right now but the power supply is the one that stands vertical and you can turn the voltage up into hundreds of volts with knobs... it's dark red. I bought two of them. They were for Electrophoresis. Bill On Tuesday, June 8, 2021 at 7:53

Re: [neonixie-l] Re: I bit the bullet bought an NL-7094

Electrophoresis supplies are pretty handy. I got a smallish one by Shandon that limits at up to 400V and 100mA. It worked a treat to fix a nixie I had with cathode poisoning. On Tue, Jun 8, 2021 at 4:04 PM Bill Notfaded wrote: > It's Paul Andrews I was referring to... I'm not at home right now

Re: [neonixie-l] Re: I bit the bullet bought an NL-7094

The most important thing to do is limit the current to the correct range, regardless of whatever value you have for the anode supply or resistor. I hope you can find a few more of these rare gems. On Tuesday, June 8, 2021 at 8:26:13 AM UTC-7 artgod...@googlemail.com wrote: > Electrophoresis sup

Thanks Greg. The datasheet says peak max is 7.5mA, Avg. max 7mA, Avg. min 4mA. Bill On Tuesday, June 8, 2021 at 8:36:11 AM UTC-7 gregebert wrote: > The most important thing to do is limit the current to the correct range, > regardless of whatever value you have for the anode supply or resisto

NIce!    I bought a similar one 25 years ago at the Orlando, FL hamfest out in the parking lot for $5. Made by CMC.  Got it home, was going to scrap for parts but powered it up only to find that it works just fine! Super accurate frequency counter, it has the reference

Re: [neonixie-l] Re: I bit the bullet bought an NL-7094

I would interpret that as 7.5mA if you use multiplexing; personally, I much prefer direct-drive because it has minimum current. So, that leaves a wide range for direct-drive; I'm inclined to say keep it on the lower end if that gives enough brightness because that will result in less "wear" via

I have a couple of HP RF sig gen that have the tunable cavity klystron in them, no nixies in those though... On Tue, Jun 8, 2021 at 11:19 AM chuckrr wrote: > NIce!I bought a similar one 25 years ago at the Orlando, FL hamfest > out in the parking lot for $5. > > Made by CMC. Got it home, wa
