--------------
A Canadian viewer sent me this vintage analog military multimeter (voltmeter, ammeter, ohmmeter). I had filmed this a while back and forgotten about the footage. So here it is. We'll open this thing up and hook it up to a battery and try to test some stuff. I'm not sure what military operation used this thing, but I doubt they got very much practical testing done with it, as the ranges are too far off to be practical for really much of anything. If you have ideas on what military used this, please comment below.

When I was a kid in the late 60s , we’d go to the army/navy store. You could buy all kinds of cool shit . Helmets/bayonets, patches , old uniforms . It was awesome for a 10 year old ! ☠️☠️☠️🤟🏼
They are called "captive" screws
That's the term I was searching for. Thanks.
@@TheGuitologist Also, that "type" of fastener is called "captive fastener." The Military still uses many types of them.
@@TheGuitologist if you don't know what the fuck your doin' call a WW2 amp tech.
Sung to the tune of Call an Amptech
Man, that meter takes me way back to my earlier USAF years, working on the oldest operating ATC radar set on the planet, back in the late 70s - early 80s. 99.99999% 50s era vacuum tube technology. The 0.00001% that wasn’t a tube circuit was a transistor video amplifier circuit that replaced the original one. You would have *LOVED* it, Brad! Mocking up equipment on the bench, looking for burnt components, swapping out tubes, and most fun of all: occasionally de-soldering, replacing, and soldering in new tube sockets. The only negative was that even though it was an Air Force Base, you’re still under the FAA, who would get pretty antsy if your ATC radar is off the air for a couple of hours. Then, after a couple *more* hours they’d start *really* breathing down your neck. It could be a lot of pressure, but...yeah, you would’ve loved it, man.
Love old military stuff...My Family runs a family care home and takes care of disabled vets and have for 35yrs and counting.😎🇺🇸
IM AN OLD DV , THANK GOD FOR FOLKS LIKE YOUR FAMILY, GOD BLESS
@@bellesmom238 thank you sir 🇺🇸
Just the thing for fixing valve amps on the frontline. Neat.
Old electrical stuff is just cool to me. Thank you
Glad you like it. I'll keep an eye out for any other cool stuff like that.
Thanks Cory.
A friend of mine's dad was an engineer for Raytheon and designed the the fueling connections for missiles. Man did he have some neat meters and test equipment.
Military training in 1980 was on a similar looking but more features AM/PSM 7. After a while you learn to flip the range until the meter reads near the center of the scale then look at the switch setting to figure which number is your reading. the one exception is voltage, on that you start at the highest scale setting on the switch and come down. The meter should work on voltages without a battery, it’s just used for Ohms. Decent digital meters are so cheap now it doesn’t make sense to lug that thing around but it does look cool.
We used a lot of this type of test equipment in the Navy, mostly HP equipment including the famous "bubble up" frequency counter. VTVM's were the order of the day to set up airborne electronics and RADAR. I built a couple of Knight Kit projects when still in mid school. Great memories!!
great to see your subs building up quick
Heh... Well I've lost about 3000 of them in the last month.
Guitologist Channel 2
Bro, 3,000? I’m sorry, Brad. That’s weak.
@@Fixologist1 me thinks its probably yt doing bot banning again. i saw it with a bunch of other tubers.
Hey Brad, Cool old meter. I know that one, red, red, red, 2.2K, use them a lot. Good video Brad, like the good old day's. If you got the time, ways and means, perhaps a scratch build of an amp you would like to have, that would be a good series of videos. Wishing you and yours all the best and every Happiness from Oregon, Cass.
I've gotten a look inside an old prc-77 backpack radio and it was wonderfully built too. The problem with stuff like that is usually proprietary connectors and things like magnesium batteries. Really cool piece Brad, :)
I think the dial instrument itself is made by ""Gruen watch co." and put in a box by triplett, just my 5 cent. That place it in the time frame as before 1958.
Same guy sent me another one that has Gruen on it. It's almost certainly late 30s or 40s.
Awesome to be back to breaking down vintage electronics!
Excellent video. More please.
Brad, when on the 150V selection, you should be looking at the 1.5V scale. the .5 would then be 50 the 1.0 would be 100 etc. That would make each line 5 volts each, so for nine volts it should go to just left of the second line on that scale. In order to calibrate the meter you should do a zero test. Put selector on resistance and short the leads. Then turn the screwhead at the bottom of the meter movement until the needle is right on zero. If it zeros correctly, but still gives inaccurate measurements, then some of the resistors in the circuit itself has drifted and may need to be replaced.
I know... The problem is the scale isn't that easy to read for most real world voltages you might encounter in DC. Hard to tell 9V from 12V.
@@TheGuitologist The problem with military equipment, is they usually had things that were specific for the task. For example, the Signal Corps puts in a requirement for a piece of test equipment that can do certain things. There may be another piece of equipment in the supply inventory that can do the job, but because the requirements don't match exactly, the bean counters write up another procurement document. They get a piece of equipment built by some company under contract with all of the specifications in the request. Pretty soon every job in the military that requires a similar piece of equipment, all have their own specialized version, instead of having one that can do everything needed by everyone. They still do this, but it has got better over the years. I know in my branch of the Engineers, we have equipment that no one else in the entire military has. This meter served a particular purpose. I would guess it was used by the Signal guys (commo). They were not checking for random things and wanting to know what the value was, they were using it for specific tests.
I have AN/PSM-4D Multimeter Says Navy department bureau of ships on front made of thick bake lite plastic "50's" I think. It was given to me 30 years ago. Needs work.
You made me go dig it out! Z.K.
Thanks, Brad. Nice little meter!
'I always prefer going in the back'
No wonder she kicked him out.
Yes sir, captive hardware was the standard. Should still be! Nice old VOM!
Of course it works!!! It was made by people who had pride in their work. Not by companies who maximize profits over quality.
The only thing that would have made that any cooler would be if it had a couple of obscure tubes in it. Thanks Brad.
Love that WWII piece of history. Now you need an alignment data sheet to go along with it so you can calibrate the meter.
Thanks, I love old stuff like that.
Woh, that thing is sooo cool looking. Killer that it kinda works, too. That’s awesome, man.
Back of what, Brad? I’m confused and innocent. lol
Just love these videos, very interesting.
sportsmans guide is a great place to find old military surplus stuff. back when military spec meant something
I have some cool old Heathkit Tube Multi testers.
I think that's awesome, love any and all older military stuff. Best to u friiend, have a great weekend
This meter looks like it was made to support field telephone circuits and possibly ordnance firing circuits. A meter like this wouldn't be too useful to work on radios as the ohms per volt would be pretty low. In other words it would load down the circuit under test and give false readings. Basically with this meter you are looking for shorts and opens and indications of voltage present.
Yeah, I’ve struggled to see much use for it in real world scenarios. Testing for shorts or the presence of voltage is about it. Accuracy is out the window.
@@TheGuitologist I wouldn't be too concerned about what other "techs" say about your methods. I have some 50 years of military and civilian electronics fix-it experience and I find it amazing that you are able to troubleshoot stuff without formal electronics training (I'm assuming). I am learning from you actually and it has made my troubleshooting experience better and faster.
Lots of Canadian engineers at Operation Overlord .Maybe British , being from Calgary Alberta Canada.
It is a beautiful piece man -- I'm sure it weighs enough to throw at someone when the civil wars starts.
You mean Tuesday?
I was going to say those had to be heavy duty because field servicing a microwave at Gettysburg was hard enough, but I don't want to sound disrespectful, so . . . never mind.
That's some real Forbidden Planet gear there man. Looks like you ought to be scanning for giant spiders or something with that bad boy.
I sure do like your release rate lately.
Probably still top of the line and in service in the Canadian Military.
Clean the switch! Check the resistors.
Let me know when the time traveling Guitar Center dumpster is ready, I assume that thing is calibrated for the trip?
That is awesome. Thank you for sharing, sir.
This_f###ing guy This is interesting. Did you mean “caught”?.
nice video
8 cell @ 1.5v == 12v. so 8 C or D batteries in series.
sure, but AA or AAA cells will fit inside the case easier.
You can do a triplet did and use an A23 battery. Our local Kroger carries them. They are 12 volt alkaline the same size as an N cell. in your use they will last probably the shelf life of the battery. N cell holders are available on Amazon or eBay for a couple bucks.
Just use 8 x AAs in series.
It does say "8-CELL" inside the unit.

In the early 70s I went to a 2 year "tech" school in Mo.. got a BA in electronics. It was taught by retired Navy electronics instructors. Oh the "Sea Stories"!!! One of them had one of these on his desk! In 1971 Texas Instruments came out with the first hand held calculator. It had 4 functions.....ad, subtract, multiply and divide! It cost $80 . I did not get one. I used a slide rule! It looks a lot like a Simpson 280, what used to be the holy grail of volt-ohm meters. A analog deflection is handy for checking things like a tremolo circuit in a guitar amp. Love from NW Colorado. Thanxz
In through the outdoor! Just pretend I didn't say any of that. Lol. ;) Stay safe Brad man. Dude's got a screw loose man!!
Do you think the lacking tolerance comes from old components with drifting values ? Id be interested if a full refurbushment of the components would improve accuracy. I dig this old equipment!
I don't think it's that inaccurate, it's just the scale jumps from like 150V all the way to 3V scale with no in between. So that means 150V is the top of the scale in one case and 3V is the top in the other case.
Way Cool meter. I'm surprised they don't have a non polarized capacitor across the meter.
I wonder what the strategy for the next civil war will be? It wont be North vs South but rural vs city all across the country. It will be unique war that's for sure.
It'll be along ideological lines. I mean, you're seeing the battles lines right now - ANTIFA and BLM types claiming the civilization that came before them is systemically raycyst and their media and Democrat cheerleaders, against the silent majority, Republicans, conservatives, and classical liberals. Inasmuch as those lines parallel closely the rural and urban lines, you're right. But the basis for it all is a false understanding of the complexities of history. It is an ideological POISON PILL that has been slowly introduced into society for at least the last 15 years, and had grown nuclear since 2015.
@@TheGuitologist completely agree. Im just curious as to how the physical aspect of it will go. Will all the people who are still sane organize and will it become an actual war or are we just going to spend the next X amount of time as individuals protecting our property from looters and rioters while these leftists further infest our system and it becomes 1933 in Berlin? I find all the Trump = Hytlur memes funny cuz if anyone actually read their history books the exact opposite is true. I dont see a RNC group rioting in the streets causing havoc, eliminating historical monuments to replace with their own and cause a chaos to bring in a new order, but I see alot of J funded dnc groups in masks and rioting. Its like the chinese curse says "i pray that you live in interesting times."
would look great as a guitar, pedal ?
I said a pig nose type amp.
God damn I love that Brad is back!
As soon as I saw the 12 volt battery "array" I thought of your lawn mower. Funny, the things you remember.
so what would be the purpose of this device? for a radio guy or a repair guy? engineer? not sure would love to know.
Screws which are designed to not come out all the way are referred to as "captive screws".
I'm not convinced it's necessarily military. I have a couple of old "AVO" meters (British) from the 1940 s or 50s and they are also built in a similar, robust way and work perfectly.
😎
bummed you didnt put the viariac on it
Never realised there was analog multimeters. Thought that was just a digital thing.
Instead of using the battery array, couldn’t you just power it using your variac? I’ve never used a variac...does it only supply AC voltage?
This meter only operates on DC power, be it from batteries or a rectified source. A variac only works with AC.
My Simpson 260 is more accurate and still works fine I have had it thirty plus years and was used when. I got it I have fluke and Phillips DVMs and they are very accurate but I like the fact theta it’s got a analog meter I find it much better off quick trouble shooting
Eight 1.5v batteries. Whatever(largest) type that fits.
My free Harbor Freight DVMs, never last longer than the free battery.
hey Brad how you doing thanks again for your post thing got a little confused there when I heard the perfect civil war multimeter I'm saying to myself civil war multimeters something ain't right there LOL yeah America always make great ship back then I had a 19 I think 27 radio you know one of the wood ones that looks sort of like a walk a mantle clock and the spot of my dad's collection and I brought it upstairs from the basement and it had the original to see original wood Nas everything was on it and I hooked up like this. Why are to work and it actually worked I was amazedone of the tubes maybe or something and it didn't get very loud but without even a real antenna the thing work I was just amazedyeah we used to build the best things in the world you know American industrial complex and all that stuff it's a shame that it's all gone away anyway thanks again for your posting I love that kind of stuff sincerely yours, Bob zipline bedroom guitarist guitarist
Old Electronics, and the components, had style. Modern components, and things built from them, look sterile in comparison.
Cloth wire vs PVC
Turret boards vs PCB
Tubes vs Transistors
Carbon Comp vs film
Paper in Oil vs Greenies.
Multi piece metal enclosures vs plastic, or simplistic cast aluminum.
Etc, etc.
It’s expensive to build in the old style today...it’s a “premium” feature.
Noob question: Brad, is Gain the same thing as Distortion?
No. Gain is just amplification.
To quote George Harrison from the Beatles Christmas Album: "Aye, it's wonderful stuff".
Similar to an old Simpson or Triplet multimeter used by the Army Signal Corps.
Here is a link to a 1940's electronics catalog with lots of interesting stuff in it.

Where are you located(country/state)
I have an old tube mic and I will be looking for someone to maybe restore.
Nice video.
I maintain that an AVO 8 MKIII is the perfect multimeter for the coming war.
I know, WWW II, the mid 40's...I liked the 60's. Especially the one, before 70. Sorry ,but you still haven't answered my question.
Wow! Cool! I’ve got an old Hickock military o-scope (that I wish I knew how to restore and use)... Am I seeing you back in your old house, or is that the new bench looking more like back at the old house?
back in world war II you know on most of the players in the war their machinery and their technology was pretty pretty pretty pretty much advance I had a clock that was taken out of a German fighter you could have thrown it off the empire State building and it would have still kept sincerely yours, Bob the blind legend guitars
Believe its US Navy, WW2, Strap looks British/Canadien.
It's got the correct paint color. I thought that too. Or maybe Korean era. But WTH were they measuring with this kind of limitation on range?
@@TheGuitologist Think anything shipboard; Comms, radars, sonars, controls etc. For quick status checks on the fly rather than bench work.

I know this is a guitar related channel but I was just wondering bread have you ever seen the miniature tools that the Nazis were making for their aerospace needs I'll say that were about the size of a thumb or a thumbnail half the size of a thumb that they were using in their planes and other stuff to get things smaller and more into it yeah these tubes were amazingI don't think there was any other country that was producing tubes the size of what the Germans were using during world war II later on in the year in the year and towards the end of the war just amazingworld war 2 technology will live in the results of it it's amazing that out of all the horrors of war machines you know what Goodfellas come eventually out of it anyway this is definitely my last timeyep last comment of nonsense or whatever Cecilia Louis, Bob the blind pension guitarist guitarist :-)
