    "did anyone rock a portable CRT television?" Well yes. I grew up in rural Australia in the late 70s/early 80s, and my parents were both dentists. Our only family TV for some years was one of these 2" B&W jobs, which my dad got as a free gift for bulk-buying a whole barrel of alginate or something from Ivoclar. We kept it when we moved to Melbourne, it was some time before we upgraded to a 12" B&W. It was eventually stolen by some druggies when we briefly lived in North Fitzroy ๐Ÿ™ In fact the reason I encountered this video is that I've been searching on eBay for one that looks like the one my dad had. It isn't this one but it's similar.

    Very handy for a portable retro pong game.

    Seeing the 1.8W of this device made me wonder how that compares to it's lcd counterarts of the ra, and in general how the power usage of larger crt's compare to the same size lcd counterparts.

    OK, junior… those are AXIAL lead components. Not radial.

  9. Avataaar/Circle Created with python_avatars Bill Martin says:

    Right off the bat: That slip-on magnifier looks like a great double for a shade as well, for viewing in daylight!
    Too bad it doesn't have a D/A converter built in!

    Outstanding. Japanese technology๐Ÿ’ฏ๐Ÿ’ฏ๐Ÿ’ฏ

    Wow it king of spooked me when Dave's hands first came into frame. by itself, the TV looked considerably larger and then these giant paws burst into the scene

    Nice little TV, I would have bought one of these if I could have afforded it at the time. It would not be too hard to fix that if all the screws and parts are there. The transistor for the H-deflection is probably in the tin can where the transformer is located. I would like that little TV, and does not matter if there are no broadcasts. I could put a small transmitter at my home and play what I want at a level low enough that the FCC would not mind.

  13. Avataaar/Circle Created with python_avatars Joao Martins says:

    Hi! Fix it!

  14. Avataaar/Circle Created with python_avatars William Gottlieb says:

    I hoped when he turned that thing on, he would pick up some old episodes of the Paul Hogan show that have been bouncing across the landscape for the past 35 years or so.

  15. Avataaar/Circle Created with python_avatars Robin Sattahip says:

    Bring back old school stuff.

    I actually had a black and white CRT TV/AM FM Stereo Radio/Dual Cassette Recorder … ect all the perks detachable speakers with built in woofers.. yes all of that and took it to school everyday with my brothers Nintendo to play Super Mario and watch shows during recess… yes I did say recess lol it was approx 2"x3" screen and Mario was smaller than the eraser on a pencil.. did not only take it to school I took it everywhere! Wish I still had it…

    Love to watch your teardowns, as well as many others who do teardowns! I am just starting to get into electronics as hobby and didn't/still don't know anything but learn every single time I watch a teardown no matter who is doing it lol… I love taking things to bits to see what really is going on in there but neglect to put them back together (not mentioning hoarding goes way back in my family)! At this time I have 2 CRT TVs a Sanyo and can not remember other; microwave; 2 CRT Sensormatic Video Monitors date code 9642 black and white, a brother 2600 intellifax got for $25 works but no cables; a laptop soon to be 2; 2 KEURIGs identical; several motorized gadgets; a handful of cell phones (non-smart); and bits n pieces of an uniden Stereo Satellite Receiver UST-7000 with original remote lots of LEDs and segments for Sat. Position/Clock, Audio, Channel so many fun things;…and a whole lot more like CB Radios and other MP3 and Stereo type stuffs… So much to build from them all and no time to touch any of them til I can get my 4'x4'x7' tent cleaned out and ventilation redone so that I will have a work space for all this.. yes that is going to be my workspace not sure where to put everything til I can get to them…

    And love the dumpster dives all of them for one I have to live vicariously through that now cuz here in Montana and many other places they either patrol or have someone posted at all the wonderful "Green Malls" and will get fined and/or arrested for dumpst….shopping for supplies… I am also not allowed at this point to bring anything else home anyhow til I have everything else taken care of..

    Thank you for all you do to help us and yourself learn and understand new things!!! sorry I kinda ramble… oh what I wouldn't do to have even 1/8th of the things some of the YouTubers have/had/thow out/etc… and just a splash of what they know and can do with what they know…

    You need to expand the Ariel so it isn't broken!

    before analog TV went away i used to use a portable 5" black and white TV as a alarm clock to wake me up with the newes(mosty in hope of a snow day in the winter) and the more inportent one was i used it to keep track of thunderstorms when the power when out and before the power went out as it ran on batteries and a antenna. thats a thing of the past now, if the power goes out i just i wait a few hours then walk to the nearest gas station and call the power company(comcast dumb ass phone systems runs phone threw cable modem)

  19. Avataaar/Circle Created with python_avatars John Robinson says:

    Wish he showed it working.

  20. Avataaar/Circle Created with python_avatars John Smith says:

    Would you be able to fix it?

  21. Avataaar/Circle Created with python_avatars ZomB1986 says:

    I wanted to see the CRT to it's bare glass

  22. Avataaar/Circle Created with python_avatars mladen ackoski says:

    you will need a serious antenna even for UHF and please fix the CRT

  23. Avataaar/Circle Created with python_avatars tenghz says:

    Can I stream my iPad on one of those? Wirelessly of course, please. Thanks in advance.

  24. Avataaar/Circle Created with python_avatars BlackWing Cyper says:

    lol the russian woodpeaker

  25. Avataaar/Circle Created with python_avatars FennecTECH says:

    Hey dave would you fix that portable tv ?

  26. Avataaar/Circle Created with python_avatars Nicholas Ogrizovic says:

    Hey dont joke around with the Russian wood pecker. +EEVblog

  27. Avataaar/Circle Created with python_avatars C6 Modellsport says:

    If that CRT worked properly it'd make a half-decent gauge in an antique car for something. Bunch of those showing engine vitals would be very Fallout.

  28. Avataaar/Circle Created with python_avatars Djordje Lukovac says:

    Dave,replace that vertical deflection chip.

  29. Avataaar/Circle Created with python_avatars Seegal Galguntijak says:

    This beauty deserves a repair and to be preserved!

  30. Avataaar/Circle Created with python_avatars MrMaxeemum says:

    Fix it / turn it into a small oscilloscope.
