1941 STROMBERG CARLSON model 542 restoration and repair PART 1

This lovely old Stromberg Carlson console radio has been in its owner's family since new. It is a true survivor - the cabinet retains its original finish and light patina - and it even worked when I applied restricted power, as these old valve / tube radios often do.
It does have the usual issues though, and I will attempt to put it back into reliable working order.

Great job Don. A nice long video on this topic was exactly what I needed to make my day. Restoration videos are becoming more and more scarce.

Hi Manuel. Glad you enjoyed it. This should be an easy restoration but a nice radio when it’s finished. Cheers

I love old tube type radios and this Stromberg Carlson is one of the best. I'm so glad that you're restoring it I sure am looking forward to the next episode. Gene from Tennessee.

Hi Gene, Glad you enjoyed it. It's rare to find a radio from this era in such good condition - especially the cabinet. Part 2 will be along in a couple of weeks. Cheers

Haha.... well played Don, I'm still smiling 😄 I'm traveling around and completely missed this video. All week I've been getting obscure references to tea bags in the comments and couldn't work out why when there was no speaker repair in the video. All the same your speaker look pretty impressive when you had finished it. The tubes of Liquid Electrical tape seem to be clear with blobs of black. Great job on the radio so far and finding the bad solder was clever, hard to find something like that. Looking forward to part 2 Don, Cheers and take care 👍🙂

Hi David, I knew you were travelling from a comment on your last video and I was thinking "He'll see it sooner or later Ha ha!" Just a bit of fun. Every fault is a puzzle waiting to be solved. The bad solder was just circuit tracing 101 but I do think I should get myself a signal tracer. Any that you would recommend? Cheers and safe travels!

Love the dial glass on this one Don. Looks like it will be a nice radio when it's done. Should sound great too once back in the cabinet

@Donno308 Жыл бұрын

Yes I think it will come out pretty well. I haven’t seen another one of these radios before. I think they’re pretty uncommon, so all the more reason to do a minimal restoration on the cabinet.

Interesting use of teabags 👍 I sometimes layered toilet paper with nitro as it seemed to mimic the original materials quite well and retained some flexibility.

@Donno308 Жыл бұрын

Hi Klumpy, That sounds like a good idea too. The teabag idea came from David Tipton of "Dave's Radio Adventures" - a great restoration channel. hence the "Tipton's Tea Bag" reference. It did work rather well though so I would recommend it.

You are doing well Don, i like your methods of fixing the dodgy mechanisms :-D. Sanding a tube in a pillar drill was ideal. Ok ideal would be a tube that was spot on without any work, but that would be no fun lol. I did detect that you wanted something to eat, sausages may have been your desire. Dam i want a sausage sandwich now :-D. Teabags to repair speakers, that must be a crime 😀 You are not the only man to solder to imperfect wire, mistakes are a good reason to swear lol. Keep up the good work Don :-D.

Hi Harvey! Unfortunately there was not a sausage to be had. A sad situation indeed. This radio seems to have more than its fair share of dodgy solders & wiring. More to come in part 2.

@Roundymooney Жыл бұрын

I have to say I was expecting a bigger chassis inside that beautiful and upscale cabinet. I'm sure it'll sing though-best of luck with it Don.

@Donno308 Жыл бұрын

Yes it's a typical 5 valve design and only 1 short wave band. There's plenty of room in the chassis and I suspect that they used the same chassis for more complex sets. That's pretty typical of the radios from this era that we get here. I have only seen one that had a noticeably bigger chassis and that was the Kriesler Projectographic. But even that was only a 6 valve design (it had an RF stage). Very different to some of the American radios I see on KZfaq with heaps of valves and huge chassis.

@rriflemann308 7 ай бұрын

my thoughts exactly, a beautiful cabinet, and a very cheap chassis, ( the fake preselecter buttons surrounding the dial are a giveaway.)

Nice repair of that speaker. Might be worth replacing the voice coil dust cap. I have an identical speaker in an STC radio of similar vintage to yours and the dust cap was missing which allowed dust to get into the voice coil gap causing scraping. I blew it out with compressed air and glued a new dust cap into place. Problem solved. (Tipton tea bags eh ;-)

@Donno308 Күн бұрын

Hi Ian, The radio is now back with its owner. Perhaps I should have put a dust cap on it, however these speakers didn't originally have dust caps. It probably would have been pointless anyway because the rear of the voice coil is exposed to dust etc. as there is no spider as on modern speakers. Cheers

I wont one. I love that dial and the shape of the cabinet looks so nice and fancy ! For as grand as the set looks it has a rather low tube count.

@retro_tech Жыл бұрын

Maybe the extra bassyness is because of the added weight of Tipton's massive teabag? Anyway: that looks like an amazing radio! Really impressive cabinet. Looking forward to your next video.

RE your tea bags I have a coffee purcolator and it uses a paper filter to contain the coffee where the hot water passes through. The paper filter is quite light and is much larger than the Liptons tea bag it might make a very useful speaker patch.

@Donno308 Жыл бұрын

Not a bad idea! I’ve never got into filtered coffee myself - it’s either cheapo instant or espresso for me, but I’ll give them a go next time. Cheers!

Don, I used to use the same solder sucker as you. However, they were not that great, seem to clog easily and sometimes hard to use. I switched to "ENGINEER Engineer Solder Suction Device SS-02" off of Amazon. So much better. You may want to try one if you have any issues with the type you are using.

Hi Ian. The speaker baffle is 37 X 46 cm. I guess an extra cm or 2 to turn over the edges so 40 X 50 would be ideal. I do have a suitable piece of Airzone cloth. It's close but not identical, so if you have the identical material that would be great.

Why do you not use stand-alone, DC power with limited current power supply for capacitor testing/training? Why do you use variac? Until diode tube is not working, there is no sense to use it. Even simple DC/DC PSU from some Liion battery can deliver 400V and few miliamperes for cap training. Just clip it to cap and check current!

@Donno308 7 ай бұрын

Good point. I don't have a stand-alone power supply bit I think it's about time I bought or built one.
