I have an HP3456A with error 3 that has to be pinned down
Yeah, now that we know it's the inguard logic at fault, I'm curious which chip is the culprit.
Anyone need a HP3437A system voltmeter? Trade ya for some nice RF & high Freq cables? Really I don't need it, so pay post and leave a note below. (you may enjoy my soda ramblings).
Thanks, I already have a couple.
My plan is to use one to add digital amplitude measurement to my good old analog scope. See section 3-53, Oscilloscope Accuracy Enhancement.
watching them blow these nixies reminded me for a great glass blowing show I got to see in Munich. Hopefully the skill set has been passed on the the kids will get of there damn video games and keep at it.
Oh, yeah; the Dalibor nixie tube video is almost 4 years old, I figured it had been seen on eevBlog somewhere. Honestly, no idea how I missed it myself for so long.
That Pilotron tube though... while eminently more primal, and actually being an active device... is quite the accomplishment as well. What I've been able to glean online however indicates that this type of valve was more a curiosity, a proof of concept rather than an actual viable amplifier... I'll admit I don't understand how his figures of trans-conductance equate into how much gain:load it is capable of.
Anybody here with better understanding of flying electron technology have any insight?

I can haz grid bias?
Those dots are very sexy.
And expensive if they go wrong
I would kiss you if you were close enough!
No thanks i think i'll pass
Yeh, probably a wise decision[emoji1787]

Interesting the 5300 A (Dot) or B (7 segment) are fairly cheap (if you ignore the freight) and lots of interesting variations on modules. The Battery/Dot one was only $19USD
Search of the NY Metro Craigslist turned up this gem among the overpriced assorted Tek 453's (Not interested). But due to my forced retirement before all the financing was in place I'll have to pass for now.
It's about 2 hours away and I'd gladly make the road trip. If it's still for sale at the end of next month (doubtful) it's gonna be in my collection.

I know that feeling about forced retirement, it sure sucks don't it. Many things you want to do have to be carefully considered, damm it[emoji17]

You got something you would like to say to me SPec? Please don't slight me again though. Be a big boy and talk it out.
Well Id like to see 18GHz on this counter, so please take out your leftover voodoo gear and poke a few things in the ass so this can happen. Even sacrfice a small animal if you need too...(as long as you eat it, right?).
We weren't lacking for signal sources - we had one of those 8620C swept signal generators with the 2-18 GHz plugin. The signal was fed into an amplifier and thence to a horn, so there wasn't much loss on that end. The problem was getting the return signal back ~100 feet from the antenna, sitting on a 3-axis positioner with a rotary coupling at the top. Scientific-Atlanta made out like bandits selling us that rig, and we still had to run expensive cables back to the receiver... or else try to get a calibrated bolometer up there that we could trust to behave in temperatures varying between 0 and 40° C. We trusted the cables more.
I don't have anything here which would generate a signal at that frequency, but it sounds like you're more in need of a way to get it to the counter. Too bad there aren't any hamfests down that way for another month or so....

Yeah I nearly picked up one at a hamfest here recently. The basic 80Mhz counter one. But he wouldn’t budge from £40 even though everything was untested apparently so I walked on.
Learning how to use these Tek cable meter test rigs, expanding the mind.
I used to do this, now I broke, and do..well this. Not my choice either.
I wish someone would force me to retire!
Be very careful what you wish for.......
Might get something done then. Currently sitting in a mandatory training session staring at eBay
Sounds like a really good and worthwhile training session then
on the other hand, not much doing on the old evilbay either
Yeah this training is “how to lock yourself into Amazon’s platform”. People are just lining up for this shit and bending over.
eBay isn’t totally dead. Got some good shit on the watch list after this weekend.
Currently semi retired for the second time after leaving my last 'real job' 15+ years ago. 'Lack of time' is the biggest issue along with the reduced income. When you are not pressed into a schedule of 5 days a week you can walk to the shops or sleep in or do X Y or Z or nothing at all. Until recently I fixed that by working 7 days a week and still doing less hours than I used to.
Would I ever go back to a real job again - not bloody likely

Which ones?
(Far more interesting than retirement planning/whinging
)
Just got around to watching the films about the making of valves and nixie tubes, very interesting, especially the nixies.
Sheesh, Mrs GreyWoolfe looks askance at me for 3 monitors on my company laptop.
The look on her face when I told her I was considering a 4th was priceless.
