Much Older (and more Broken) Than I Thought

- Going back further in time than the design suggests to me. I'm genuinely surprised by this. I'm now curious about what other devices had similar design cues during this period. The internals are also interesting. They really made these things differently back then.
I'd like to thank Inky for joining me on the desk tonight. She is so amazing, I'm honoured to know her.

I appreciate Inky very much
Yay Inky! Love the purring and that is a gorgeous device which hopefully you can get working again some day!
Shout out to inky, the best assistant the channel could ask for!
I wonder if the "wireless remote control" was something that worked sonically, like the literal "clickers" for some televisions of the era.
I love this possibility. I remember hearing about these things as well. Thanks!
Exactly that. The handset was mechanical
Kitty!!
This is a lot of videos in a 24 hour period (and I love it).
The earliest remote control I remember, is the clicker box . Which allowed scrolling through channels. All three of em😂
Is that a 1970's Zenith TV remote ?
They used ultrasound 👍
Sony WX-777 also uses the wireless remote controll. Wireless controll is maintained by radio frequency transmission and receiving.
Very interesting, thanks.
just shows how far ahead Sony was in that era compared to anyone else
3 vids in 1 hour?? WTH LOL XD
I think I'm loosing the plot
@@JanusCycle losing or loosening?
@@JanusCycleIm enjoying this content overdose 🙂↕️
I'm loosing it, loosing it I tell you. Why does this happen to me?
Channeling your inner Techmoan.
I too have a policy of carefully reassembling things I cannot fix right away. Always giving it a good cleaning at the same time of course. Much respect to you for doing that.
Currently in my collection I have:
A Sanyo record player from the early 70’s. It needs a thorough recap and a new stylus, but unfortunately the plastic chassis has become so brittle with age that any further repairs just caused more damage.
An even older Philips record player, very compact, all plastic, single detachable speaker.
A robot vacuum cleaner 😅
A Bose Soundlink, V1. It blew the power supply section, but the 2 very potent amp chips still work and can be hacked easily. 2 x 30W rms in an enclosure the size of a novel.
And lastly an immaculate Chinon 872 8mm video camera, complete with original case and all owners manuals. Japanese made, it feels heavy and solid. This one I still have to work up the courage to tackle, it might even be working for all I know 😅
Keep up the good work Mr Janus. Love your videos.
Nice video and cute cat

Yup
Shame you weren't able to get it working, but any excuse to feature Inky is a good one. Have a lovely day!
Although analogue radio tuners didn’t use phase locked loops until digital tuners came along, that was mainly out of cost and reliability as there were methods to do it in the analogue domain. AIUI a comparator would control an op-amp which controlled the voltage going into the VCO, the output of which was split back into the comparator.
It just so happens the superheterodyne principle is much cheaper, so that’s what radios use. Especially as the analogue methods still drift anyway, it just reduces it by a decent amount. (Adding a reference frequency like a precision quartz clock could help, but you needed a whole whack of other circuitry around it then. And you basically have to compare your tuner against the station’s frequency in a radio.) Digital became a byword for PLL for radio tuning as a result because it was so cheap, integrated and compact, and far more accurate and reliable.
Not to even say anything you said in the video was incorrect, as it is fully accurate in the context of consumer radio! But some Radio Guys do get the impression that that’s the only way to do it, period, in all domains and applications.
You knowledge of radio tuners certainly exceeds mine. I have so much to learn.
Did you check with multimeter if there’s power coming to the motor?
Now that would have been a smart thing to do. Thanks, I miss the obvious sometimes.
@@JanusCycle You can also give 3 volts directly to the motor to see if it starts (or whetever voltage it is rated)
If I was smart I would have tried this. Thanks for reminding me. I've been in an odd headspace recently from being unwell.
@@JanusCycle Do you have a discord server? asking directly from community is a good idea when this kind of problem occurs!
@@maxsun2418 I do, but we mostly do phone modding and digital stuff. Not many people on Discord know about this sort of 70s gear.
That is one of the best sounding purrs I have heard....
Any time I find a drive belt that hasn’t turned into goo, I consider it a win.
The mechanism looks really high quality, almost all metal! Dont feel bad about giving up, without a schematic I would have done the same. I look for a schematic before even buying a retro device, even if its sold as working.
Use a multimeter to check if the motor is getting power. Some of those models the motor seizes too. Best to start by checking voltages from the batteries.
I admit I didn't really do enough fault finding. I've been a bit under the weather health wise recently and didn't give this enough attention.
Sometimes ya just can't do a repair but it is still nice to just have.
I have a voice recorder made by RadioShack that takes microcassettes and in the back of my mind I always wondered how cool it would be to use them for music like the normal cassettes.
0:08 looks like a mini TC-D5 with the flippy door for the cassette
Nice machine that
Given that this unit had a wireless remote I think it was probably meant for journalists, lecturers and secretaries.

Could be that the drive belts have stuck to the motor and the motor can’t move? Maybe lol
The belt is a bit loose so I don't think so. But maybe I gave up too easily.
Kitty!
Might not like Sony as a company too much, but I do like their design language.
that era of Sony electronic engineering that is lost to time.
You spoil us 😂
You're worth it
Can you make a video about the nokia 3510i do you have one?
I do have one. But it has a DCT4 chipset. Very hard to mod the firmware on. I will still find a way to incorporate it into a video one day.
@@JanusCycle Yes thank you so much can yo utry to load the internet on it too?
A cat
Yeaaaah !❤
Love from 🇮🇩
Past it here. It needs service and use to do all that for this stuff, video,etc. you just need to right tools and the knowledge. Because the motor is not running don’t mean it’s the motor. You need to find the test point and scope it.
