1970's Stereogram - Part 3 - Radio Chassis Rebuild

[@knallform]

Love the Bob Ross reference, you also reminds me of Len Hend sometimes. A true artist you are. Keep up the good work 🤩#seenitall

A comment you made about factories I remember my Mum worked at the Baird TV factory in Bradford it was huge filled with women line after line all doing their bit of assembly and overhead conveyors with CRT tubes hanging going from one place to assembly. I was a kid then and thought it was magical. What went wrong we don't make much anymore but then there were hundreds of factories making just about everything we needed.

Brilliant known old school has its part in electrical equipment of yesteryear and is truly remarkable well done, you done a lovely job on the stereogram better than factory new.

Just finished restoring a 2025TC of my own - rescued it from the bins! Looking forward to seeing the next video with the upgrades, as I'm not entirely pleased with the sound from the Pfanstiehl cartridge my local shop sold me. Cheers!

[@emalaret6]

Love the videos. I love the part when you get shocked by the capacitor. I did it too. Retired electrician.

Thank you for posting 👍👍

[@davendi2009]

Nice restoration looking good so far.

[@DenHarrowYoutube]

Great job to fix so as not to throw away..✌

2:10 I used to work at Data General in the 1980s and there was this woman who used to sit at a wire-wrap machine that would move the guide to one post and make a squeak, than to the next post and make a growl. She'd load a new wire on to her gun after each growl and she always seemed to be on the verge of bursting into tears. I think the boredom of the job was slowly driving her insane; I know it would have done the same to me. Anyway, they didn't use solder on those wires; the force of the gun was supposed to cold weld the wire to the post. Maybe with these thicker wires, they needed solder.

[@jopjopjop]

Interesting! Wire wrapping is a different technique. In this case the wrapping is for mechanical stability. The solder alone is not supposed to hold the wire in place.

Need a video on that toaster!

[@peterkendell5214]

Mark, when I built telephone exchanges back in the day (1970s), wire-wrapping was generally used on the majority of fixed connections. To get them off terminal pins, we were supplied with wire-unwrapping tools. Are they still available?

[@janjohansenmusic]

How do you keep track of all the wires and stuff you remove? Do you keep it in your head or take pictures?

[@oldphrt]

He takes a video. You're watching it!

[@AdeDaviesWales]

Excellent! Really enjoyed this. Thanks for sharing. Can I ask, how long do the capacitors in old radiograms take to discharge after power is turned off? I have an old Civic that needs attention. I will use a capacitor discharge pen of course anyway. Keep up the awesome work, thanks.

[@MrPaulfrazer]

I have recently discovered your channel and am really enjoying your very informative videos. You used an ultrasonic cleaner for the switches and potentiometers on this chassis. Do you find this to be a safe and long lasting fix for pots? I have used contact cleaner and find it only lasts for a few weeks before the pot goes noisy again. Have you used it on wafer switches? I have resorted to dismantling pots to clean them along with lots of bad language and some blood when trying to get off the little ring of metal that holds the shaft onto the case! I would like a good excuse to buy an ultrasonic cleaner 😊

[@MendItMark]

I’ve had great results with all types of switches. A good solvent and the ultrasonic waves do a good job of getting any tarnish or corrosion off. I think the choice of solvent is important. Check out my Ultrasonic cleaner video from earlier this year.

[@MrPaulfrazer]

@@MendItMark Thank you - I will

[@EricTViking]

8:03 - what did you use to cut the hole for the PID controller on the oven? A chainsaw!? 😂

[@MendItMark]

I might as well have 😂The oven mod was a Sunday afternoon idea, that was more work than I thought. I got impatient and set the angle grinder on it. That was probably 10 years ago, and it’s still working!

[@EricTViking]

@@MendItMark Nice😁 As I was once taught, it ain't a bodge if it's safe and reliable 👍

[@desnick2316]

I noticed you rarely label wires you unsolder from the board. I personally would forget where each wire or screw goes in about 3 seconds. I would typically take a lot of pictures to make sure I know what goes where. How do you keep track? Are you using your videos as a reference? Cheers!

[@toolsarecool]

@17:00 he talks about it 😉

[@merlin5476]

Interesting to see that you used a sonic cleaner then a light oil..... As an amature i would have just grabbed my Servisol.

[@sabrowenie]

With no schematic, and not tagging anything, how do you track how to put it back together?

[@iankennedy1441]

Any videos on a stuck tuning knob it wont tune its stuck and wont move in any direction

[@chrismaton01]

I've no idea why I am watching a 3 part video of Mark re-furbishing/mending a radiogram. I've never had one and it's too late now! Hower, I have an iPod Nano generation 1 which needs a battery replacement and it is too delicate a task for me. Would you like to do it for me?

[@naytch2003]

Never too late..there are online auction sites and oxfam shops or op shops as we call em in New Zealand

[@ossianhaufe4671]

It is might dangerous to have a fall out from Fokushima or Chernobyl in the ultrasonic cleaner 😆 ? If you don’t have a topic for a new video you can explain all your devices and give information of the histories. I’m really interested to know it.

[@marcogarcia5323]

Si very good Hoy much bot generators signal

[@merlin5476]

At least its not got SMD.... they appear to be a nightmare to source & change.

[@keithc.shepherd8833]

Why not try spraying with contact cleaner first.. if that didn't work then take then off the board.. unless you like extra work.. LOL... otherwise good job.

[@MendItMark]

Thanks! I tend to use various Deoxit juices on my own kit, where I can reapply it every month, or so. I wouldn’t trust it for a long term fix for a restoration however. (I do like the extra work also. Guilty as charged!).

Hello salam GBU sukses selalu

Nothing worse than a wonky knob 😂🤣😂

Or loose nuts!

Oh that godawful wire wrap era.
