Education and intelligence levels are slowly increasing.... not decreasing (at least in part because if you do something stupid, you'll quickly find yourself on youtube or facebook as an example for everyone else). And I was warned PLENTY of times in the 80s and 90s not to try things at home. What the heck are you people smoking?

    I remember building my first CW transmitter from an old television set purchased as junk from the Salvation Army thrift shop for $1.00. I salvaged the excellent power transformer, but I was very fearful about putting the transformer primary across the 120 VAC power -----that would be a short circuit, wouldn't it? So I studied up and learned something about inductance and reactance. My one piece of equipment that I designed, built and operated entirely by myself was a telephone answering machine. This was circa 1970 when home answering machines really wern't available at all. I used a capacitor across the telephone circuit and when the ringing voltage came from a call, that voltage went through the capacitor and triggered a relay, set up as a locking relay. That turned on power to a couple of tape recorders, and power was witched between one that play a message on an endless loop of tape and then a thermal time delay relay switched to a second tape recorder that recorded a message. Worked reasonably well, and I never got in trouble with the phone company! I had everything nicely packaged in a plastic box. Don't ask me about the OTHER box that allowed me to receive long distance calls without the caller being billed for them....

    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 had it powered up into a dummy load, plate voltage on full, and I have the meter connected and was adjusting a sliding tap resistor with a screwdriver while monitoring voltage to the modulator tubes. At some point I got a bit careless and my index finger touched the metal stem of the screwdriver while my left hand contacted the chassis. I got full DC plate voltage in one hand, through my heart and out the other. It knocked my across the room. For a few seconds I saw a bright flash then stars, had a metallic taste in my mouth, felt off balance. When I recovered a few moments later I could smell burned flesh where the current entered my right hand. It was a painful shock and when I think about it I can still feel it to this day (it happened around 20 years ago). Since then I never entered my hands near a transmitter (or any HV device) with it plugged in and the power on. Even if I am making adjustments it gets powered down, unplugged and discharged first before my hand gets anywhere near the insides.

    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.

    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.

    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

    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!

    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 !

    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.

    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. ;)

    I had a similar shock off the tube EHT on an old projection TV. About 30kv from an overwound mains transformer, supplying the 1.5 inch projection tube .. Knocked me across the room, and boy was it painful.. Still have the scar...but still alive 60 years later..!!

    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.

    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.

    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.

    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.

    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.

    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.

I used to do that kind of thing my self at one time at one time when I worked but now am retired and to watch this video kind of brought it back to me. I will say he is good at what he does. He has more equipment than any that I have seen he must be a collector of electronics equipment. I will say it brought it back to me just to see him work.
