RADIO & TELEVISION Careers and 1940 vacuum tube electronics: This vintage film reflects the rapidly advancing technology of Radio and TV in the 1940’s, and the rise of many new CAREERS. This fascinating film highlights JOB skills needed in Radio and Television as envisioned in the 1940’s. As vacuum tube technologies grew more sophisticated and Television was in its infancy, demand was also growing rapidly. World War II increased the need for vacuum tubes and radio knowledge. Many of these technologies were precursors to the giant vacuum tube computers which followed. {Rescued and restored with improved audio/video} We hope you enjoy this great original, unedited film. Uploaded by Computer History Archives Project (CHAP). Run time 10 minutes.

I was just talking about tube amplifiers yesterday with someone in church. We both agreed that the sound of tube amps are indeed superior to solid-state ones.

@ComputerHistoryArchivesProject 2 года назад

Hi NipkowDisk, that is so true! ~ My friend has a "retro" stereo amp with the tubes exposed and the glowing warm light from the tubes can be quite "romantic" in the living room, while vintage Sinatra songs play in the background. Can't beat it.

@jamesatkinson6480 2 года назад

The tube amplifiers certainly had more of a soft, mellow sound to the 'naked' ear. Much of that was to do with the size of the audio coupling transformers that drove the speaker with an impedance as low as 4 ohms. Some amplifiers used 'Class A', which is minimum distortion, but 'Class AB' was for a greater output power...

@@GensUnaSumus09 A comprehensive description there. My first system was a 'Playmaster' 50 Watts per channel in to 8 ohms, using a MOSFET (Hitachi) output stage. It was a 'Dick Smith Electronics' kit, priced at $175.00 in Australia, representing the pinnacle of high fidelity kits, back in 1981. (Electronics Australia Magazine) Used it for 40 years, until a fire last year (it wasn't the cause) melted the internal wiring. The RIAA phono stage was notably quiet..

@@GensUnaSumus09 The 'warm' sound is just 2nd order harmonic distortion which is more pleasing to the ear than odd order distortion. They're also 'warm' in the literal sense, I can only use my 40W push-pull triode amp in winter because of the amount of energy wasted in heat.

Women have been working in electrical / electronic manufacturing for a LONG time. Many members of my family (men AND women) worked for the Westinghouse Electric Company going back to the very early 1900's. Western Electric (AT&T/Bell System manufacturing arm.) also employed plenty of women in their factories. So, contrary to what is usually thought today. There WERE women in industrial manufacturing without there needing to be a war going on!

@ran2wild370 2 года назад

There is a reason. Women could do monotonous jobs with low error rates. Men aren't good for some kind of delicate work and assemblies.

@organicfarm5524 2 года назад

Women have been working in ANY manufacturing/processing for a LONG time. And actually they have been better than men in that sort, 'cause of less volatile mind.

Vacuum tubes were fun. 375 to 380 volts dc (some had 450) on those exposed plate connectors in an old TV set. You get zapped once and forever after you were very carefull.

@ComputerHistoryArchivesProject 2 года назад

Very true! I used to fix old TV sets, and saw one of my screwdrivers get a melted tip, just from a tube discharge. Unforgettable! ~ Charles

@w8lvradio 2 года назад

Interesting that the film advises that repair is a poor entryway to engineering, and that there is an overabundance of repairmen and portable PA system operators in 1940. I would guess that by then the equipment was becoming more reliable (both radio and PA) and dealers were in abundance by this time period. 73 DE W8LV BILL

Why would I want to AVOID working in manufacturing? 🤷‍♂️Hell, I've done retail AND I have done assembly line work. Working on a line might NOT be "exciting" but it can pay well, and you don't have to deal with "Karen" or "Kevin" screaming at you about a $15.00 purchace at a Wal*Mart. Not everyone is "cut out" for college (to be an engineer, for example). Making things brings its OWN pride.

@RastaJediX 2 года назад

That's why he said avoid unless you're okay sticking with it! If so, that's cool, and there's nothing wrong with that!

@KrisRyanStallard 2 года назад

I was a machinist in manufacturing for a while. I took pride in what I made, and it could have led to a long career with lots of opportunities for advancement. Unfortunately I didn't tolerate the extremely repetitive nature of most entry level manufacturing positions, and I didn't fit in well with the people who typically work in the field. Such is life. It only took a year at votech to get the certification necessary to start in the field. A lot of my fellow students started out working on a manufacturing line and wanted to move up.

@jamesslick4790 2 года назад

@@KrisRyanStallard Being a machinist is quite a bit "above" an average assembly line worker. (My father was a machinist.) I get that perhaps you were not cut out for that career, but being a machinist is hardly "entry level" manufacturing. (I know. I stood in front of a die cutter and just literally, simultaneously pushed two buttons to make "blanks" that would later be stamped to make (commercial) bread baking pans. Not the same as precise machining. That's ART.

@KrisRyanStallard 2 года назад

@@jamesslick4790 trust me, there are lots of entry level machinist jobs out there. Nobody is going to trust you to program and operate their $20,000 a pop machines until you've proven yourself. Besides, there are very few jobs with advancement opportunities that don't require some sort of post high school training.

@johnchildress6717 2 года назад

@@KrisRyanStallard Some machines cost half a million.

@KrisRyanStallard 2 года назад

Interestingly, women are highly valued these days in skilled manufacturing because of their superior attention to detail. If you're a woman who likes hands on work and problem solving, get training to become a machinist and you'll never be out of work.

@ran2wild370 2 года назад

Well that makes many clues why first computers were called Colossus. Those control panels were assembled from what the industry already had and accumulated.

Men will do important jobs, and the women will do lighter tasks! :D

@jamesslick4790 2 года назад

"Lighter" in this case has nothing to do with "importance". The women shown were assembling radio components. If that's not done, All of the radio engineering is pointless. SO their work was IMPORTANT. It's a fact that women over all have less upper body strength, So few are going to be tossing V-8 engine blocks around, But women have been in electrical manufacturing since...Well since there HAS been electrical manufacturing. I have WOMEN ancestors that worked for Westinghouse Electric who built everything from circuit breakers to refrigerators going as far back as 1905! (and NO, Not "just" in war time.) P.S. Women in "higher" tech levels is also not NEW. I had a great aunt who was a process (film manufacturing) chemist for the Eastman Kodak Company in the 1930s!

I like how for most of these jobs, the narrator essentially says they are dead-ends and you are pretty much a failure if you pursue them. Oh yeah, and no women 🙄

@ChatGPT1111 2 года назад

Well men taught the science, created the technology, then started the companies where men built all of the structures that made the parts and back then almost no women had any interest in these types of jobs. I'm 63 and my grandmothers never once mentioned being interested in any of it but my grandfathers loved and experimented with this type of equipment.
