Dose anyone know what this

 

[junkyardhero]

an early version of the power probe?

I'm thinking the globe in the center has some form of vacuum tube below it and when the probes are touching something ( old radio?) and the probes are measuring the same, the tube in the globe has a glow that is centered. I remember something like that when testing tubes for old TVs back in the day

Maybe a Model T Buzz Coil tester?

would you post a better photo of the name plate / part number

There was one at the Chrysler Dealer I worked at back a while I never seen anyone use it

I take it you don't have it in your possession?

It's a whatcha-macallit...

Nice wall hanger. Stromberg was a carb company. I have an early vacuum gauge from them with real Mercury in it.

That is a really nice piece. Stromberg in Chicago made all kinds of test equipment...I would love to have that for a man cave hanger.

What Dana posted is called a "tuning eye tube" or "indicator tube." In tuning eye use in radios, the tube worked off the radio AGC/AVC (Automatic Gain Control) voltage which increased more negative on strong stations. Those tubes had a high impedance input similar to modern multimeters, AKA they did not "load" the circuit they were connected into. They were also used on condenser/ capacitor testers. But that could also be something like a neon bulb.

I searched "Stromberg HRL" and came up NADA "High Resistance Load?" No idea

What is inside the black spark-plug boot shaped wire? Does it look like it connects to a coil?

 

[MILO]

It is a clamp There is 2 clamps and 2 fat probes

Ok, so the two clamps go on the battery or power source (I wish it had another nameplate with ratings on it) and then the two probes likely drive the "globe" which I assume is a vacuum tube, probably cathode-ray. It could possibly detect voltage signals between probes similar to a Oscilliscope but very low tech.

So my bet is it is a very old version of a high voltage wire tester (like a spark plug wire tester very early)

That is a very different device. Sort of like nixie tubes inside a crt, 'er some'tun

 

[grjammer]

An early "null" voltage tester. The two probes must have the same input voltage to center the globe indication. A comparison meter, or zero difference (null).
i used digital versions to test very old radar equipment that still contained tubes.

Yes I know but thanks. It's just an example of what they made.

Got one of those, still works never use it........ but it looks cool on the shelf.

THAT'S where I remember it from 1976-1980 Highschool Electronics class! Capacitor tester!!!!

I went through Air force electronics/ avionics 20 plus years ago, have an associates degree and then at some point I went to get hired at an electronics shop guy wouldn't hire me said I wasn't experienced enough and he was a foreigner wanting to pay me 15 a hour I walked away like "wha?"

I'm not making a negative comment here just asking if my assumptions are correct.

In the military my understanding is there are SOPs for all repairs. Most electronics / mechanical components are segmented. Meaning if a device fails the SOP says test here, here and here, then replace this board or that component.

Is that a correct assumption on my part?

Reason I ask is way back I was in an electronics class in college and a veteran with electronics training ( he serviced all kinds of electronics in his service) was in the class and he struggled to understand things to the point of almost failing.

So basically he could repair a radar unit but not understand how electronic circuits worked.

My question is not a slam on our military in any way. In fact it's a great way to insure that a device can be repaired by almost anyone should the people tasked with it are unable to perform their duties.

Oh no not taken negative I was just amazed that the job didn't pay well on the outside. is all. It surprised me but electronics aren't what they once were these days and things are disposable etc. And yes I've known guys who could work aircraft but not be able to change a fuse in their truck its just that they are trained to do one thing on one piece of equipment etc.
