I had one of these when I was a kid ! I was going to a class to learn CW and theory, on my way to get my novice license ....! It worked pretty well, the ham I bought it from showed me all about the HV items and how to tune it up. I can still the remember the smell of the dust burning on the tubes ! lol

"when people took responsibility for their actions" true words right there. Great video yet again mr. Carlson. Love watching these!

"This was built in the 50s, an era when people still took responsibility for their actions" 😂 Couldn't have put it any better!

I would have given my left arm to have your tutorials on demand when I was 10 years old and even younger. I had no information back then. Just fascination , electrical toys to take apart and the odd electronics project kit. So great Carlson Thx.

i am 78 years old now, but when i was a kid in detroit area, W8BXO, doc. weston, taught me everything about ham radioˇ bless his souľ Great show

Mr Carlson you have the perfect voice and tone for your videos. very professional.

Great video! My first transmitter as a novice was a Globe Scout 680a, very similar to the 40A. That 5 pin connector in the back that looped the heater and B+ through it was used for when out in the boonies. A 6 volt storage battery would light the tubes and a dynamotor or vibrator pack would provide the plate voltage. Many older receivers had the same loop through plug/socket. My dad was a ham too. Today he was born exactly 100 years ago today. He has long passed though. But it was cool to see this today. Dave-N2DS

I was having a really bad day, then I saw your video and while my day is still kind of bad, it brings some sunlight into it. Thank you!

Im a new broadcast "engineer" hire. I am in awe of the ingenuity and brilliance of the engineers before me. I feel really dumb when I look through their old mods and hand drawn schematics. I fell into this job and want to say thanks.

Yes, I want to see the modifications! Thank you for this beautiful piece of vintage gear! 🙌

I love this tech Im 64 years and studied the old hetdrodine tube type tv and radios. Dont see much of this at all anymore. Thanks for the video.

So much of this just goes over my head, but I still enjoy watching these videos.

I have a Globe 300 it was a product of WORLD RADIO LABS of Council Bluffs Iowa One of THE Big Ham Radio sellers in the late 40's and 1950's and they were SO Big that they decided to put out their own line of Transmitters 😅 which basically competed with the Johnson Viking and Ranger transmitters. WRL is just one of the great names of the Ham radio history's Golden Domestic built gear era. Wonderful memories......

“An era when people took responsibility for their actions.” Love it 😊

Yes, please show modifications! I had one of these back in the late 50's; brings back a lot of nostalgia...

Yes please to the modification video!

another fine quality natural selection helper device, we need more things built that way ;)

Always impressed with how good of a communicator Mr Carlson is. Literally everything of importance is explained, proper safety warnings are always given. Another excellent video!

That tuning reminded me of tuning up the old radio teletype sets back in the 1970's they were some powerful units, could talk around the world with them if you had the right antenna, we took over an old marine compound back in 1971, the jar-heads had two poles that had to have been over 60 feet tall with antenna's strung between them every so many feet. Buddy of mine had to strap on some Gaff's and climb those poles to tear down their sets and replace them with antenna's cut to our frequencies. Now I took the Field Wire-man course back when I first enlisted in the Army and we climbed poles for a week, but I would have been scared to death to climb that far. Ah well, I do envy that old buddy of mine; haven't seen him since '71 but I did hear from him in '77.

Wow! This takes me back to the 1950's when I was a boy and did all kinds of things like this. I don't know how many vacuum tube radios and TV's I scrapped or repaired back then. But then I went away to college, discovered computer programming, and that changed my life forever.

A "thumbs up" FROM Mr. Carlson is very high praise indeed...

An era when people took responsibility for their action: how true this statement!!!!!

A modification video on this RF amplifier would be marvelous Mr Carlson! I'd be interested in signal clarity and RF power increases for example.

Oh what memories you have brought back. There was the Globe Scout, Globe Chief and the monster Globe King. I still have much of the old AM transmitting equipment like an ART-13 from WWII Aircraft. Lots of high voltage there. LOL

you make me miss my former head tec. don foster so much as i am now 78 and sow much water under the bridge so to speak ( we were in portland , or. usa ) thank's carl stout . can't beleve i have forgot so much !!

Great video. When I first got my general in 1959 I built a Globe Scout 680A which was similar to this one, but ran more power. You have a great way of explaining things!

Boy did you bring back very fond memories, owned one of these in the early-mid sixties when I had my novice license along with a National NC 303 receiver....thank you Dad, (miss you).

Thanks for article! Reminds me of my early ham radio days (ex-WA2YTO) and my original transmitter, an EICO 720, also with a single 6146.

Smiling! Back in the 80's I worked for Missouri Radio Center/MOcom. The owner took in an old WRL Duo Bander 84. World radio labs. I gave him 15 dollars for it, took it home. To my surprise it worked on 80 and 40 meters, after I cleaned it of all the hay and bird poop. Took it out of storage a few years ago and not working so good. Your video may have inspired me to try and get it running again,

I have several vintage 1950s AM transmitters like this including a Globe King 500, made by the same company that made the Globe Scout. However the Globe King is considered a "500 watt" transmitter consisting of 3 decks mounted in a rack. Namely a power supply desk, a modulator deck and an RF deck. It is basically a 4-400 tube modulated by a pair of 811''s. Also have a couple 100 watt category plate modulated transmitters including a Johnson Viking 2 (early 1950s) and a Johnson Viking Valiant (also 1950s). I've had them all on the air at one time or another. Just for the record I am a licensed ham.

I want to add his electronics course is the best I have seen. It also covers surface and through hole, tube , and PCB making.. Awesome course !!!

I have learned so much about transmitters from these vids!

thank you most kindly for taking the time to fully explain what (and how) is going on with these circuits, you are definitely an old school ace, a rare breed these days....and...who knows how to explain it comprehensively to boot! thank you sir.

"took responsibility for there own actions", what a wonderful era it must have been...

As a ham this is a great looking rig! Pleasure to just watch the thing come to life.

WRL made great equipment. I enjoyed watching this video very much. I had the Globe King 400C that put out 400 Watt on AM. It was rock solid and I had all the coils for the 20 - 160 Meter bands. I had a Johnson Viking 122 VFO and a wonderful National 183D Receiver. There are a couple of pictures of me with my rigs back in 1958 on my Facebook timeline. My call sign was K9BYI. I got my novice license when I was 11 years old. Looking forward to seeing more videos on older ham gear.

Modifications are always fun. Would love to see them.

Love seeing your vintage electronics presentations .I began my journey in electronics at the age of 12 am now 62. You are absolutely the best instructor. You remind me of a couple of my first instructors in advanced electronics and color television design and circuitry classes in 1971 @ ft. Bliss & 1975 Homestead afb . And of course my father who started it all and i learned about radar and guidance systems from. THANK YOU !

I have fun when I visit Mr. Carlson's Lab!!

I wish that I'd had a video like this when I started in electronics years ago. Well done, sir.

My Dad had this radio back in the 50s. I have always wanted this transmitter, good find. I have my ham license too, but ham radio is not like it used to be back in the day. I see the old filter capacitors have been replaced with a bank of new electrolytic caps. Electrolytic capacitors become trash after 10 to 15 years.

Yes, please. Mod it up. Really look forward to that!

Hello, Paul. I just wanted to say, thank you for sharing your knowledge on vintage electronics. I grew up basically tagging along in my grandfathers Radio/TV shop. Just recently, I decided to restore some old equipment. Your channel has been such a valuable resource for me. I look forward to following along on Patreon as well. Keep up the superb work and your passion for teaching electronics.

Love it! I started out in my teens working on old black & white TV’s then tube type CB’s. Grew up in far West Texas (120 miles to the closest city, El Paso) so I didn’t have much access to any other gear. After high school and marriage I went to a tech school and was in the first class that didn’t teach vacuum tube theory. So I learned it pretty much on my own, so I really enjoy watching and learning more and more about the nuances of vacuum tubes. I am currently restoring a 1929 Radiola receiver and man has that ever been an education. Hand wound wire resistors “cards” for lack of a better term. “Mystery” components as they are referred to in the literature, which just turn out to be a negative feed back variable capacitor, but Radiola was not labeling it on the schematic in an attempt to skirt around a German patent on the circuit design. Wholly different world than other vacuum tube gear I have previously worked on. GE Pre-Progress, and Progress line, Motracs, and Mastr II and Micor high power base stations & repeaters. Great video Paul. Side note: I was taught that a pi network was called that because the schematic was shaped like the Greek letter pi. Please “Hot Rod” that transmitter, I would love to see your improvements to that circuit.

Wow. I have never seen an older tube-type radio in action. What an excellent presentation! Modern transceivers make things so much easier and a lot safer! I would love to build a tube-type transmitter one day and operate CW. I have a passion for Morse code. 73 de AD0WE

Another great master class in appreciating useful electronic gadgets from the golden era ! Very much enjoy the value of your experience and knowledge in this field, and safety warnings not to attempt working on these without proper methods and understanding. Between you and Uncle Doug, I have returning interest in electronics that I had a young man. Thanks for your effort !

This is the video which I credited for giving me interest in amateur radio licence. Ever since this I saw this video and got my license I’ve been hunting around for globe equipment (which is extremely rare in the uk) and hit the jackpot a few weeks ago with a globe king 500B tx just 100 miles from me so I’ve just got to get the full license now. Keep up the good work making sure this stuff is saved. M7BLJ Jake

Yes, I would like to see !

I don't know that much about electronics, but watching you doing your thing does three things for me: 1) Total relaxation. Seriously, watching your videos takes the stress right out of my day. =) 2) I learn lots of things. Your explanations and methodology alone are worth a college course. 3) It inspires me to dive further into the world of electronics myself. I love old electronics. To see them restored and appreciated so much is very satisfying. Thanks for doing this.

I've always loved electronics and poked around with it. You have got me hooked on playing with vintage systems Thank you

I know you're just being diligent when you warn us about the high voltage and the like but I'm guessing most of us who watch your videos come from the school if you stick your finger in a light socket it your fault not the company that made the light socket. Love your videos. I've learn more than I care to admit watching your videos. Thanks for taking the time to produce them.

I'm so glad you've decided to depot the transformer from the previous video. That's going to be so cool to watch!

"when people used to take responsibility for their own actions" Subscribed...

I still have a Globe Scout 680, that my dad built from a Kit, back in the mid 50's. He or I could never get it to to work with a VFO. Worked great with crystals. Your video has Inspired me to drag it out and preserve it, Been in storage many years. Thanks for your very informative video.

Wow...beautifully made and crafted transmitter! and equally beautifully made videos Mr Carlson...although a little bit much addictive ;) ..can't stop watching one after another...I appreciate the high quality of your scripts and communication style. Thank You and Keep-on the good work!

Perfect video me, thanks. I'm in the process of homebrewing a AM valve based transmitter. :) Good caution notes on high voltags :)

Yes, Mr. Carlson! Hot rod the Globe Scout transmitter, please! I learn something every time I watch you work on this old gear. Today I learned the meaning of 'dipping the plate current', something I've always been curious about. Thanks!

"This was built in the 50s, an era when people still took responsibility for their actions." And we had a much saner and better functioning society as a result.

What a great video. I operated a Globe Scout 65A, a later version of this one, when I got my Novice license in 1955. The Globe Scouts were very affordable but unrefined. Constantly replacing the transmit switch was a way of life for owners. The AM modulation was ‘screen modulation’ which is a cheap technique. These were typically used by novices on CW. I bought mine new and paid $ 100 wired and tested. A kit version was available for a few dollars less.

Thanks for another great video Paul! Ya know... One time I got a nasty hit from a Heath DX-60 but I never considered blaming Heathkit for that. :-)

Sure would like to see mods to the transmitter, Very nice video, keep them comming. Greg

I always love watching old stuff get a makeover for the modern times :)

Always a pleasure to see a new video from you. Your detailed information about every part of the equipment nearly gives me goosebumps (-;

Thank you sir for another great video. I still use my old Swans. Also like you informing the new folks about B+ and its potential for being lethal and being responsible for your own actions.

Ahhhh, another video featiring the smooth, dulcid voice of Mr. Carlson. Nice....

Yes, please do "soup it up" on the Globe Scout! The first transmitter I ever had was a Globe Scout. I missed it so much that a few years ago I found one at the Huntsville Hamfest and bought it. Sadly, one of my X's family stole it and I no longer have it. Have not seen any since the last one that I bought. Looking forward to the "depotting" of the transformer too.

I still think the Internet and computers really did a disservice to the younger generation. I am 66years of age , and grew up in the age where we could build our own home brew sets, and shortwave and ham radio were just so much fun, because we were actually trotting all over the globe with air waves and no physical connection with coax such as with cable television! Slow scan ham radio was so cool!

My father (who recently passed away) told of a gentleman named Buck who stuttered so bad it was almost impossible to understand him. But, when he keyed his mic, all the stuttering went away. This was back in the early 50's, so I'm guessing this is the kind of equipment he used. Dad said he was always welcome in Buck's ham shack, but was forbidden to go in when he wasn't there... Now I know why :-) Wish dad could have seen this video, thanks Mr Carlson :-)

Wow, That's one of the radios that I started with when I got my novice license. This brings back many great memories. Thank you.

Awesome, Thank You !! Mods are most welcome!

Mr. Carlson, Thanks so much for every video you produce, especially your Patreon Videos. I learn so much every time I watch one and I’m amazed that I’m retaining a lot of this information. I’m also having a great time learning. I also learn a lot just reading the comments and your responses. You make the answers to so many of what seem to be, very complex questions, seem fairly simple just the way you answer them. You are such a class act.

I had HIGH voltage go through my hand once when I was working on a Transmitter. Almost 3rd degree burns. I still have the scars. It was MY Fault. LOL. It doesn't hurt to be electrocuted, but when you wake up...if you do, and your hand is on fire and smoldering, nothing takes away the pain except Demerol in the Ambulance. Morphine does nothing for burns. The voltage melted/punctured my fingertips. Your body part doesn't hurt for about 20 minutes because of the adrenaline, but after 20 minutes it's unbearable. I learned a valuable lesson that day. Never have both arms inside a radio at once if you can help it. Take off all rings and Jewelry and only plug radios into a Variac and Isolation Transformer to work on them. ;)

Very informative and explained very well. The only thing that I would have liked to have seen, was how the cw note sounded and what the a.m. modulated signal sounded like through a receiver. I gave you a thumbs up for the video.

Ahhh, the good old 6146. Years ago, Just about every transmitter I had, used them and never a problem. My first was a Heathkit DX-60B as well as a Johnson Viking II. I miss them now as I homebrew solid state these days :-)

Thank you for sharing this vintage transmitter…… It would be nice to see some cool mods done to it……. Stay safe……

thank you great to see the old transmitter and i would like to see this transmitter give a make over and made safe!!

Thank you for explaining how the circuit works, very educational. I enjoyed it very much.

Loved the video - it takes me back to when I was a kid in the 70s and my Heathkit DX-60B with a matching Heath VFO.

I would very much like to see more RF / HF, Tx, Rx projects Paul. As a new Amateur and a Patreon following along in your Electronics Course, I'm finding your training highly instructive in working towards my Advanced license. Many thanks!

Mr Carlson, you are a celebrity!

EXCELLENT video!, I was the kid(old dude)in the remote class room with his hand up all the time while you were going over schematic by the way ,Ha

One of the wisest statements you have made, "back in the 50's an era when people took responsibility for their own actions" So very true and a lesson many should learn from. Those were the days when NO ONE would buy a wire antenna and many of us built at least 1 transmitter, feedline, our antenna relay boxes and we repaired our receivers. We depended on the elder Ops in our community for advice and parts if they had them. No hand holding and no cottling. When we were old enough to go off to college and exams came, our professors didn't bring kittens or Lama's to help us cope with the stress. You either passed your exams or repeated the courses; no excuses either way. What has happened over the last 50 years??? Not saying all of the latest generation are wimps, certainly NOT. However way too many are.. I'd vote for modding the xmitter as well. I would not be surprised to see audio improvements byt trashing the 2 RC packs in the audio path. It would also be interesting to look at the signal on a spectrum analyzer and see if improvements could be made to improve the second harmonic radiation. 73, Glenn WA4AOS

Yep! Definitely like to see the follow up mods. Thank you for your content!!

Sweet! Looks like I'm not going to bed yet. Thanks Mr Carlson!

YAYE finally something worth watching on "the KZfaq" im always happy to see you posting a new video.

My vote is probably too late, but I would love to see your mods to this unit. I'll poke around, maybe you already did one. F.Y.I. I spent my first two years in the Air Force working on AM avionic transceivers (AN-ARC793 and AN-ARC546) that were installed on the F4 fighter. Lots of fun with tubes and high voltage and motorized mechanical tuning. We eventually retrofitted these planes in 1981/82 with an all solid state modular unit AN-ARC164. Back then I had all the latest and greatest test gear that I don't have now. Thanks, Mr. Carlson, VERY interesting and instructional video.

Very cool, thanks for showing how the old tube circuitry works.

Thats the great thing about electronics, whatever sphere one is into, and no matter what your skill level, there is fun for all, such is the diversity of our great hobby.

Cool transmitter. It reminds me of the Heathkit DX-60 I built in 1972. That was the first year the FCC decided that Novices could be trusted with VFOs, so I also built the matching unit to free me from being rockbound. My receiver was a beautiful old Hallicrafters SX-101A. 73’s from the former WN4BCG.

Hey that's a pretty cool old radio. I have never seen one of that era, thanks for sharing & letting us see it.

Yes would like to see the Modifications !

Wonderful and very interesting,Thank you.

If it's on Mr. Carlson's channel it's fun!

Love these videos! Highly educational and interesting for a electronics enthusiast

Such a beautiful transmitter! Thanks for the video.

Wow, great video, certainly for us old timers :-)

Absolutely great stuff Mr Carlson. Love this channel.

very cool piece of gear, i wish my grandfather were around to see your vids! RIP: WB3GNR

B+ is Battery plus . Hey Mr CARLSON i am totally fascinated by the way you are teaching us vintage and nowadays electronics. w2aew and you are two of my favorite electronic - channels. Thank you and many Greetings from Hamburg Germany .!
