Repairing and aligning an antique radio, Stromberg Carlson 240

Ғылым және технология

This video shows from beginning to end, the repair of an old radio from the 1938 era. This Stromberg Carlson 240-H chassis was the Cadillac of the time. It's an 11 tube superheterodyne receiver with push-pull output, an IF section with 3 selectable response curves, and a lot more.

    The restoration of vintage radios is becoming more popular all the time, as the vacuum tube technology is appealing to people as most of the media equipment today is not easy to repair, or certainly not as easy for a technician as is the case with a nicely designed wooden vacuum tube cabinet from the past.

    I have been following Mr. Carlson for several years now. I love his shop. My shop is a foxhole in comparison, but I too earn a living in my retirements years, restoring monochrome and color television, Radio, computers, iPads, iPhones , vintage test equipment and RCA 45 RPM record players of the 1950’s. I also build Theremin devices fabricating my own printed circuit boards. Electronics has been my life’s work since 1962. My last gig was teaching electronics at Swarthmore College and providing equipment support to the plasma fusion physics lab under government grants.

    As a recording engineer I should know more about the pixies in the pipelines, but I know just enough to not get electrocuted (I'm more of a cable-running, knob-twirling kinda guy), but I have to say I really enjoy watching these restoration videos. Somewhere from the distant past things my high school electronics teacher said comes back to me through the fog. But one thing that does come crystal clear is how much you love your work, and it shows in the precision, care and expertise you display. If I ever had a precious piece of vintage gear that needed to be restored, no matter how much of a hassle it would be to get it to you, I would do it. Wonderful stuff!

    I’ve learned so much from your videos and just wanted to thank you. I’ve always had an interest in electronics, but never pursued it either professionally or educationally. I learned the basics and used to tinker as as a kid, but at 50, I had barely touched a soldering gun in all those years. In the last year I wanted to introduce kit building and soldering to my daughter just to see if she had any interest. As it turns out, not really. But the bug bit me again so I looked up heathkit and purchased one of their clock kits. Feeling nostalgic again, I decided I wanted to buy a turntable to play all those albums I collected back in the 80s. That led to me building a phono preamp kit. I just wanted to keep building kits but there really wasn’t anything for me to build that would be all that useful for me (so I thought). That had me looking at the few non-working antique radios I had collected over the years and thinking, I can fix that! To get started, I hit KZread and was happy to find lots of great info. I had an inkling that capacitor replacement was going to be the primary concern here and that led me to your many videos on the subject. It’s only been a few months and thanks to the pros like you I’ve restored a number of old radios and have purchased many more on ebay that will keep me busy over the long winter. You and your peers even inspired me to start taking videos of my work and start my own channel. I’m really glad to have discovered this new hobby and again, wanted to drop a comment to thank you for the knowledge and inspiration.

Plus the great sound as result of the typical low noise figure these tube radios are producing when there's no station transmitting and the "warm" sound of the filters/ speaker chassis do produce. I love it! Nice restauration for a nice radio. BTW: I always thought the linear bar-graph like magic-eye would be best, but having seen this radio the eye-like one absolutely got me. Kind of hypnotic... ;-) Thanks for the nice video, nice job!

    Wow, a little over 7 years. I remember watching this video when it was first posted. I was looking for some quality content in the post 2021 holiday lull and decided to revisit some early Mr. Carlsons Lab videos. It's hard to go wrong there, right? This Stromberg Carlson 240-H is still drool worthy. Thanks again, Mr. Carlson. I'm a big fan of Stromberg Carlson radios from the 20s and 30s. Much like Stromberg Carlson telephone equipment, they're built to a high standard and often quite heavy compared to their contemporary counterparts. The pride of my radio collection is a S-C Model 1-A battery radio from 1924. It's a typical 5-Tube Neutrodyne set from that era, but it's beautifully built and would likely survive a 10 foot drop with no substantial damage.

    I was thinking of putting together a Crystal radio, also known as a cat's whisker receiver. Would it be possible to play it through a speaker if I used an audio amplifier?

    Yes, but you would need an extremely high impedance pickup like 10Meg ohms. Otherwise, you will load the circuit too much and you will get very little in the way of output.

    Hi Rachael. That means your Grandma's radio is hearing whats inside the TV. The TV makes all sorts of radio waves when in operation, those radio waves can also be called oscillations. TV's have oscillators everywhere inside to perform different functions.

    Hi there, I just subbed this morning. I'm an older guy who's getting ready to take the plunge and learn electronics (not a complete noob, but darn close) and what really made me sit up and take notice was what you said about cap replacement. I watch a lot of restoration videos on the KZreads (I can absorb a lot through osmosis, LOL) and what everyone else does is what you talked about; chopping a lead in half and soldering in a new cap at the exact same location. In some cases, they're making the leads longer. I'm not married to the idea that the inside of a radio has to look stock (there are some who use the paper sleeves from old electrolytic caps and "re-stuff" them with modern caps and hot glue) I just want it to work as well or better than stock. Bottom line; maybe in a future video you could show us what choices you make in the re-capping process. Not a full re-capping, as that would be tedious like you said, but where and how you would relocate caps and wires. Thanks for a nice clear, non-handheld video, as that really makes it better.

    I understand basic electronic component but I do not understand what you are describing. However, when you run through the working of the radio describing the parts and their functions you do it so well it seems to flow like music. I still don't understand but I find it immensely interesting.

    Anti-theist Hated this episode. Terminologies used are obtuse and occlusive; ie, “Barn door” is ‘promiscuity’ and “fidelity” is ‘monogamy’! I don’t follow the logic behind how misapplied analogy allows two extremely opposite lifestyle-descriptions to share commonality with a discrete parameter of electrical device frequency-response adjustment. Surely the lingo is from time-honored basic accepted convention, but ethereal semantics are actually obstructing all actual learning by supplanting truth with other bs fake cognitive head-knowledge.

    The 6X6 vacuum tube was what Rogers Tube Company of Canada numbered their green eye tubes. You rarely see them today. Sparton (of Canada) called it a "VisoGlo" tube which is more commonly known as a "Magic Green Eye" in the states and a "Cat's Eye" in Europe for such tubes.

    Mr. Carlson, I wish I could have you restore a Yaesu FT-101 that I have. I think it was already recapped, but it might not have been complete, and it needs to be retubed and neutralized. There's probably other stuff that needs doing on it. I repaired the planetary gear, but the electronics has been beyond me. I'm trying to learn, in part by watching your videos, and eventually will probably do it myself, but I would hate to mess it up, because the FT-101 is one of my favorite amateur transceivers. You really do incredible work, and I'm at least getting a good example of how to do such things methodically and carefully. If nothing else, your example will inspire me.

Since that time, I have continued to work on repairing nice old radios, similar to what you do, mostly for the enjoyment I get from doing so. I would love to know how you learned what you obviously have, about electronics. Would love to know if you were trained in electronics, in a school setting, or if you are self taught; perhaps you are a ham?

    I just found one almost identical, but with the left side square, sort-of, with the superb "cyclop" lamp.. It has been opened but I"m sure all major parts are present, speaker cone seems in good shape, lamps are all there, over-all is pretty darn good looking, excepted the front plastic display disc is cracked, the little window on the (great condition) wooden case is perfect.. don't know if it's functional because I don't have the knowledge required to test.. and I would'nt want to get it worse. Long story short, I'll be more than happy to wrap it very well (lamps wrapped in foam, etc..) and mail it to you, I'll even throw 20$ on reg. shipping, no insurance from Qc, Canada. (If I spend more, gf will go crazy, saying she says it's a piece of junk eating space and collecting dust.) I think this piece is worth something (not money, that would be an insult) and I honestly think you understand my concerns about the future of this superb piece of history. Otherwise I'll put it for free on whatever marketplace-alike site, it must go, garbage is not an option and the gf is getting on my nerves, kinda..
