You prove YT shorts are vastly superior to Tictok schlock 🤙

[@saravanar7140]

Very true ❤🎉

[@notavailable9479]

huh! they both have their merits if you know how to wield them

[@sanoops3555]

😂 tictok is just trash buddy

[@HamzaSeyar]

Did you know that he posts on tiktok too? The first time I've seen his content was on tiktok bruh. Stop judging something without even trying it.

[@glengbh]

Awesome. Sometimes I can't quite believe that humans created all these amazing circuits.

[@stevehageman6785]

I worked with a lot of these sorts of hybrids. You are correct the 'funny' part is a tantalum capacitor. The wire sticking out is the tantalum anode.

[@WolfmanDude]

Man that must have been a pretty nice camera if that was the vidicon output amplifier!

[@robinbrowne5419]

Hmm.. I used to have a chip made by Intersil back in the 1980s. But I can't remember what kind of chip it was. I will post it in a future comment if and when I remember. Keep up the great work on these interesting videos 👍

[@Ray_of_Light62]

Vidicon tube DC to 10 MHz output is in the range of fractions of Pico ampere. That is why the front-end is built with such a precision: high frequency and high impedance are hard to engineer together. Video cameras from the '50s used a dual triode, cathodes commoned together and grounded thru a voltage stabilizer tube. Basically a tube differential amp, where they stripped the DC components, and reinstituting them after amplification. The amplifier in this video keeps the DC instead.

[@chrisdickens4862]

It’s fascinating to see what they did with a few pairs of matched transistors and resistors. Very simple compared to even old op-amps, but yet still high performance.

[@346L3]

Fascinating stuff. I collected a few old, still working Video Cameras with tubes (microscope Vidicon camera heads, rugged Newicon surveillance cameras from 1982 that support 1080i resolution and a portable color one that records directly to VHS). I wonder if some of them have similar components inside, but I won't disassemble them. :)

[@petergibson2318]

Made 7549. Just before Christmas 1975. Almost half a century ago.

[@HaakonAnderson]

Crazy right! Imagine how far it will go in the next half century.

[@MiharuNV750]

Вот удивительно, что применялось такое сложное корпусирование для такого простого изделия, 2-3 десятка элементов. Я сейчас делаю аналоги гибридок для ремонтов старой аппаратуры - все то же самое делается на SMD элементах на маленькой печатной плате (правда с 2 сторон как правило). И в принципе тот же усилитель можно было сделать просто на основной печатной плате, практически в тех же габаритах, даже на односторонней и на thru-hole компонентах.

[@thunderinvader9031]

Ну тут суть наверно в том что это готовый масштабируемый в производстве компонент

[@xxportalxx.]

​@@thunderinvader9031likely had better guaranteed performance as well. Fully shielded enclosure, matched components, etc.

[@JohnVance]

Somewhat integrated circuits!

_"Vidicon"_ *_"Now, that’s a name I’ve not heard in a long time. A long time."_* - STAR WARS [1977]

[@rayoflight62]

Vidicon, when compared to the more complex image-orthicon, allow for a definition of many thousand lines. Being the target of a vidicon a photo conductor, it is easy to use any pyroelectric material and build a good infrared tube. My bet is on this amplifier from early '70s is part of an high quality infrared visor...

[@marcodelao9148]

once again, ceramic chips are beautiful!

[@ThePrimaFacie]

I really like your content, thanks for it. I had a Q. and or comment. Wondering if you could flash the old company logos when you say the company names. Although I have no clue how that would hit the algorithm and or copyright. I just think that little silk screen (or however they placed it) "i" logo maybe iconic and or any other old Logos. It might just be too much work to do for little gain. IDK Thanks again have a good one.

[@douro20]

I wonder if the resistors might be tungsten on silicon? The process HP used to make their FOCUS 32-bit microprocessor actually used a vapour-deposited tungsten interconnect.

[@r1w3d]

Got any close ups of "lead whiskers" on any old tin solder contacts? Probably never on the inside of any component like these but with the age of some of the parts it made me wonder. I find it a lot around old AM transmitter parts, that and BBQ rodents...

[@benchjoiner8418]

Can you also say what year it was made please?

[@frogz]

most chips and components are listed in this format, 7549, 49th week 1975 on the front of the chip

[@paveltube80]

n 2016, Intersil was acquired by Renesas Electronics Corporation, a Japanese semiconductor company. The Intersil brand and technology continue to be developed and sold as part of Renesas' portfolio of products

[@zaprodk]

The blocks with a pin sticking out are Tantalum caps

[@timwilson8118]

Nice camera work.

[@bekahmed5048]

Thank you very much... What microscope is used in the experiment?😊

[@nv-offroad]

Looks like an Al203 thin film substrate!!

[@WooShell]

If you want the right Vidicon tube for this chip to saw apart too, let me know ;-)

[@parsipax6337]

if i only could click like before clicking your videos...

[@Maxey428]

I would pay for HD pictures of a few of the microscope pictures

[@frogz]

edit: he posts them to his webpage and i guess a few on his youtube community page

[@nickgardner6340]

cool stuff

If you get a chance please open a STK series IC used in audio amplifier.. please..🎉

[@frogz]

i took so many of these apart as a kid, found them in old tvs/vcrs mostly

[@bl1ndfx403]

woah

[@phillyphakename1255]

Yeah, that burned out tantalum looking thing looks like a burned out tantalum.

[@msylvain59]

Just a naked tantalum, if it was burned there would be marks all around.

[@alexhajnal107]

@@msylvain59 Interesting to one naked. I'm used to seeing them in pretty orange packages.

It's perfect for trans resistance. Lol. I'm just going to leave that one sitting right there.

People invented all these and china could mass produce it any day?

Ohhhhh....... I was thinking it was for Right Wing mouthpieces. Ya know, being a trans-resistance amplifier.......
