- Buzz from CZcams Channel Buzz1151 sent me a radio to restore. That was nice of him I thought... until I opened the box!
I have the radio working but the speaker is toast. Also the rust, so much rust. Can I fix both to get the radio looking and working as it should? RCA Victor 26BP

Crazy that some time in this radio's history someone went through the effort of repairing the speaker instead of replacing it. Brilliant repairs as always.
It has an unusual mounting set up so it seemed better to repair it than redesign the mount, that may have been the thinking of the previous repairer as well Thanks abcsd1254 🙂
Well, you brought that speaker back from the dead great job
Thank you Ripley 👍🙂
Kidding aside David you are the best restorer of old electronics on the internet! Shango and others could learn a lot from you if they wanted to! Thanks for posting and take care!
Aww, thank you John 😊
What better than to wake up on my birthday morning to another Tipton's radio adventure. 57 today, not as old as that radio I think. Great job on the speaker, a few clever ideas on centering the cone and magnet. Loved it. 😊
What a coincidence! It's also my birthday!
@@zenithcoinsandhobbies All the best people were born on this day 😁
@@radio-ged4626 Very true!
Hey, Happy Birthday Gad 🎂 Thank you, enjoy your day 😊
Yes David you are the best restorer of old radios👍👍👍.
Maybe not the best but thank you Claes 🙂
Nice video. Loved the little ad hoc 3d printed tool to help get the speaker cone reattached.
The 3D printer is a handy tool, thanks Arrr Ummm 😊
I love how you guys can salvage speakers! I worked in a radio/tv shop in the 70's and we would send speakers out to a local shop to be reconed for a couple of dollars. Cones are available from China but they typically don't include the speaker coils. I haven't tried to recone a speaker but I have a huge box with 4 inch speakers that need to be repaired. I'm 78 and still involved in electronics. I worked in IT for 32 years and ended up teaching IT for another 12 years after I retired.
The day of getting a recone for a few dollars have passed. The voice coil and cone are sold separately bus it's very hard to get a cone with a small enough voice coil hole, they more suit the bigger magnets used today. It's good to be busy in retirement. Thanks George👍🙂
_David has golden hands. You are the best in the whole world._
Thank you Domenico 😊
Hi David... never seen a speaker built like that, 😱.....I certainly picked the right man to save this RCA radio....Magnifico job! 👏👏...... I am buying you 2 beers for your hard work.🍺🍺
Hey Buzz, me neither, I was amazed when it came apart like that. I was even more amazed when it went back together 😄 Thanks for the beer Buzz... haha... beer buzz 😅🍻
@@DavidTipton101 here's a fry and burger to go with the beer Buzz🍟🍔
😅
I knew that you could fix the speaker. Waiting for part three. Have a good weekend.
Thank you Stanley 🙂
Mr. Tipton, well done completing the radio and speaker repair. I am very much looking forward to the case restoration. Thank you again for sharing your radio adventures with us CZcams yobs!
Thank you mrgunn. The case will be a challenge... next week 🙂
Well Dave - amazing job restoring the battery case and the speaker repair/restoration was "out of this world"!!!
Thanks Kenneth 😊
You old radio guys are amazing. Well done Dave.
Haha... thanks Red Spot 😊
Another great example of saving what appeared to be long gone...battery frame and speaker. Looking forward to the case next time. Thanks, Dave!
Thanks Joseph, we have to do the best with what we have. Case repair next week 👍🙂
Thanks for reminding us that most radio parts can be repaired, not just replaced...transformers, speakers, metal frame pieces. Can't wait to see what you have planned for the vinyl-ish covering of the case.
We don't really have much choice but to rebuild components these days and most where made inhouse so are fairly simple to reproduce, it's good fun too. Thanks Don 👍😊
So much work, but really worth it. Looking forward to part 3.
Thank you dogribmoon 😊
Yes I did enjoy that, looking forward to the next episode, David!
Thanks Michael 😊
David: You sir are a mechanical genius! Well done.
I'm not sure about that but thank you John 🙂
I always look forward to the next video. Thanks for the interesting and instructive work!
My pleasure Vlad, thank you 😊
I am a very early riser and it's nice to have a Dave Tipton video to watch while the sun is rising. Nice work on the speaker.
Thank you Wayne 🙂
David excellent work on the speaker refurbishment we used in day gone bye 50 Hz from a scope. Soldier iron That bought a lot good memories.Ian.
Thank you Ian. Good thinking using the scope for a frequency 👍🙂
David, thanks for another Great video. I'm not sure how many of your viewers realize how "professional" your final video product really is! I enjoy and appreciate the work you put into each episode. You are very precise and intentional with each camera angle, lighting, proximity to the task at hand, choice of narrative and rewarding us with the final product! Fun watching the speaker study and repair, the framework rust solution, and the asbestos replacement product put into place. I always look forward to your next video! (BTW...I never get seasick with your camera work.) -Chris
Thank you Chris and thank you for noticing what I try to produce. I enjoy the editing as much as the radio work so it's good for me too. Haha... I try and keep the camera still 😅
Well it's getting there, Dave. Thanks for sharing.
Thanks Brian 👍
Coming along nicely David!
It is.. thank you James 👍🙂
Fine job, David. Always a pleasure to watch.
Thank you Zorka 🙂
nothing like the smell of glue in the morning ...another excellent job David!
It's good stuff 😅 Thanks Chris.
Nice one dave....great job on the speaker and the metal chassis...roll on the case...keep well.
Thanks Sean, all the best to you 🙂
Great job on that speaker. How lucky that the magnet and pole piece were held together with a screw. I never have that kind of luck.
You must be living right. 😀 Again you have set the bar.
I was a surprised as anyone when the speaker fell into pieces like that Vern. I will probably never see another like it. Thanks mate 👍😊
David, I'm convinced that if you had been part of the three man crew on Apollo 13, you would have created an oxygen scrubber without Houston Control 's assistance. Love watching what you do!
Haha... thanks kilcar 😅
Another great video David. I don't need to state how good you are at restoration, your repair of the speaker "speaks for itself".😉
Haha... pun intended 😄 thanks Jan.
Good Show Mate ;-)
Thank you JE 😊
Great work on that speaker and looking forward to the the follow up on it's case. Take care David.
Thank you Stephen 👍🙂
Impressive mate! I probably would have thrown the speaker and just looked for a replacement!
Thanks Chris. There's no fun in that 😅
Great job on fixing that speacher
Thanks Sheldon 🙂
I know Buzz would have watched this. He should be well impressed by hom many different implements you poked at the speaker without going through it 😂
Can't wait for the cabinet to get the "Tipton Touch" but it definitely looks challenging
Haha... Buzz has seen it, he and speakers don't get along do they? The case will be interesting... next week 🙂
Another really enjoyable video Dave. I would have given up on that speaker, but I knew you wouldn't. Great work!
Thanks Rene. I enjoy a challenge 🙂
Merci David , super travail sur le haut-parleur .
Be Seeing You 👌
N°6
Thanks N°6 👍🙂
Nice win in the battery box! 👍
Yeah it looks pretty good considering. Thanks tubeDude 🙂
Hi Dave good job on speaker rebuild. When you were testing the speaker with you waveform generator it sounded like a mini Didgeridoo .. AM broadcasts here on the east coast of the US are very week and mostly outside line noise it's terrible. What I did I purchased an AM broadcast transmitter , now I can broadcast any thing I want on AM another good tool.. Take care look for you next time .
Haha... it did didn't it 😅 I have a transmitter, I must set it up one day too. Thanks Paul 👍
Nice work on that speaker... Good job!!!!
Thanks Chris 👍🙂
Nice speaker restoration. I never knew what to call that temperature resistant cardboard stock. Will have to see if I can get some pressboard online. Looking forward to seeing how you restore the roll-up front cover.
That's what it's called locally, quite useful too. Thanks Sincerely 🙂
11:45 Laser cutter? Cuts lasers, of course! LOL😁
👍
@neilforbes416 Your'e a cut above the rest.
@@Mediawatcher2023 Snip, snip!
OMG David, what a bonkers brilliant idea to put some juice through the coil to centre it. Never ever would have thought of that but now I've seen it done it's an obvious procedure. Now that's something I'll carry with me into my next incarnation (ha ha). All the best mate.
Hello Stephen. I saw it or heard about it many years ago, I remembered it when I was having trouble fitting a shim in the gap. Your little workshop must be in full swing this time of year 🙂 Cheers.
Nice job Dave! That case looks like it's made of papier mache. Good luck with that!🤣🤣
Thank you Antony. The case is an interesting construction 🙂
''What could go wrong ?'' Ha Ha Ha, a lot of things actually but as long as it happens on your bench and on your watch you'll fix it. I don't know what impressed me the most in this episode: Actually fixing the speaker or designing and building custom tools on the fly to get the job done ??? Probably both. You're the man to beat in this game David. Well done, well done indeed ! You deserve a raise.
Hello Raymond, thank you. I have passed on your request for a raise to the higher power but I don't hold out much hope. Something about new shoes or a handbag, I forget which😄 It's nice to have the gear to make little helpers but it can be done without it. Cheers, take care 🙂
@@DavidTipton101 lol, that whay i sometimes like to remain single. Just kidding Karen is a pearl :-)
geee David, regarding the battery case - "an amature effort" ? From it's terrible condition to the final item and it's appearance after your "armature effort", well, I'd bet money that it looks better now than the day it was manufactured, bravo! And - the speaker being one lucky lump of steel, paper and copper wire was very lucky to receive your attention - easy to guess that the majority of tinkerers out there would have tossed it and then cobbled something else together - I was thinking as you finished it, with your "3D tool", and care with the coil's core and such - "gawd, that man is one clever son-of-a gun!" Thanks for another great vid.
Thanks Skip. The battery frame came out OK but I should have spent more time on it, it could have looked like new if I did. I was a little disappointed in myself I guess. The speaker had an unusual mounting method so I made the effort to recover the original speaker, well worth it in the end. The 3D printer is so handy, I try and think of things to make 😄
Great work David 👏
Thank you Haytham 🙂
David, perfecta reparacion. saludos cordiales de Cecili desde Brcelona España
Gracias Cecili en Barcelona y un saludo para ti 🙂
Making great progress (less pants than before).
Thanks Ralph, I have my pants on 🙂
I hope this video draws some attention to Buzz's channel.
I hope so tarstarkusz, he is underrated for his work 🙂
Nice work, Dave! Can't recall seeing the use of a tone when centering the speaker cone or using the body filler for filling in the rust spots. And, it's been a long time since I've heard an "oh dear!" 😄
Thank you Allen. I saw someone use a tone a long time ago and remembered it when I couldn't really get a shim next to the voice coil. Haha... such utterings as "oh dear" reveal my age 😅
Hi Dave, many thanks from UK, great to watch as always.
Thank you Chris 😊
Morning David, hope you are well? 👍
Morning VRE, all good thanks 🙂
@@DavidTipton101 👏🏻👏🏻👏🏻
Nice job David. That laser cutter is really nice. 73 de KB7ICI.....Bill
Thanks Bill. The laser cutter is so accurate, if one is happy to spend the time designing the cut file it's well worth it for the excellent and repeatable result 👍🙂
G'day David, I really enjoyed video on the speaker. I just got a few radios from second hand shop in Rosewood just opened up new shop, obtained 3 radios HMV, and 2 Nationals, one broken for spares. So you've got me interested in AM radios Cheers mate. Dennis.
Good job Dennis, I hope you enjoy repairing your radios. Thank you and good luck 🙂
David is the Tubernator! The only thing missing is the cape. Then the equipment: special tools designed and 3D printed, laser cutters, medium blasters, what's next - a modest nuclear reactor to power The Worlds Largest Klystron Tube? David, you're amazing and so are your skills, and results. Bravo!
Haha... thanks alpcns. A nuclear reactor.... Mmmm 🤔🙂
Interesting to see you using a warding file to clean the aerial contacts. Couldn't manage without mine. Best file in the drawer!!!
Great job as always David and nice to see some of the kit you have accumulated to help with your radio adventures.
Best wishes
Lynton G4XCQ
P.S. if that pesky Dickel ever comes knocking at your door hide the whisky!! LOL
Thanks Lynton. I didn't hear from Dickel, the whisky will be well hidden if I do though 👍😄
Paul Carlson taught you that speaker cone alignment technique using a signal generator didn't he? It was quite brilliant
if not. Never seen it done before on YT that way. It defintiely works! The restoring of the RCA designed battery mount was
another feather in the cap as it looks great. Can't wait for the 3rd part. Steve
Hi Steve, I haven't seen Paul use that technique on a speaker, I don't recall seeing him work on a speaker. If I did get it from him I would have given him credit for it.
I think I saw it on video some years ago but I don't recall where, it was a speaker repair video... it's just a vague memory. Either way it did seem to work although I still used the paper shim as the primary alignment method. The case is a real challenge, I haven't done anything like it before. Thanks Steve 👍🙂
Someone commented below "You old radio guys are amazing". Now, did he mean that you are old, the radio are old or both? Well I think I know what he means but I will keep that to myself ;). Great job David. Look forward to see what you do with that mess they call a case. 73 Joe
Thanks Joe. I think he meant I am really really old, he nailed it 😄
@@DavidTipton101 🤣😂
fantastic job on that speaker and the cage......if the case comes up half as good im renaming it the rca lazarus lol
Haha... that is a good name Chris. I have high hopes for the case but we will have to wait till next week 😊
Fantastic job repairing that speaker! 👍👍
Thank you Robert 😊
Great videos! You've got another subscriber.
Thank you Fluffy and welcome 👍😊
I watched all your videos but missed it somehow. You have 3d printer and laser engraver 👍
Yes, both those Ibrahim. I use the laser engraver as a cutter but both are very handy 👍🙂
Good work David sir 👏 😊❤thanks for the sharing this video sir 😊
My pleasure Nath, thank you 😊
👍😊
👍🙂
👍🏻👍🏻👍🏻
😊😊😊
Dave, just put deoxit on those contacts, it works and doesn't damage/wear the plating.
Yes, agree Francis, the file was a bit rough. I did apply DeoxiT afterwards. Thanks 👍🙂
Job well done
Thank you Maarten 😊
I had a similar speaker issue recently, and was able to just remove the central dust cap, and unscrew the magnet retaining bolt, then shim around the magnet with slivers of old credit card, and retighten the magnet down. (The cone and spider still well-glued so no issues there). The speaker now works OK but the magnet is shockingly weak, so not brilliant.
That was a good fix for you. The magnet was tight on the voice coil so needed some clearance. It's not the best speaker in the world. Thanks Timothy 👍🙂
Dave, I've been so impressed with your skills set particularly in transformers and coil rewinding and speaker repairs as highlighted in this video. Your shops growing tool collection the laser cutter look like so much fun, what other projects have you done around the house?
Hi Mack. Thank you, My tool collection is growing isn't it... and I'm still married! 😄 The laser cutter is impressive, perfect cuts every time. I bought it to cut radio back panels but haven't used it to do that yet. I rarely get a tradesman in for house renos, repairs and upgrades 🙂
@@DavidTipton101 Great idea Dave maybe think about a back cover with antenna coil like ones so common to American types.
Start the grandchildren making radio covers to order for the radio restoration group.
Good morning David
Good morning Haytham 👋
Hi David, once again a great video. Loved the speaker repair & especially the re-centering, I,m still trying to work out why the tone input?
I have never seen a speaker like that, very unique design indeed, we certainly learn't a bit from this video !
Cheers
Hello Baz, thank you. The tone keeps the voice coil centred in the magnet core, the tolerance was so tight I thought it needed a little help. It seemed to work pretty well and I might use it on other speakers to see if it really effective. I saw someone else do it many years ago and though it would be worth a try here 🙂
I wll try this technique on the Breville speaker I'm doing this week, mind you the cone is going to be a real challenge !
Good luck, I'll check on your results 👍
A 'speaker factory would have left a shim in while the adhesive cured, but I guess you got away with it!
That glue is very thick it grips instantly 👍
You do some through work. I just replaced the speakers in my truck a few months ago. I wonder if they could have been fixed.
Thanks clasicradiolover. You can buy replacement speakers for your truck, a better option I think 🙂
Mr Tipton! You're a bleedin wizzard, you are.
Haha... thanks Mat 😊
Hi David, Gee that's an unusual speaker. I've never seen one constructed like that. Anyway, nice job on it!
I'm wondering why you decided to apply a signal to it while fitting the cone? If it moves freely and doesn't scrape it will work, won't it? I feel like I'm missing something.
Cheers
Hi Don, me neither, I was in awe as it came apart, I don't know why they did it that way. The low frequency sinewave centres the voice coil, the gap was so small I wasn't confident I could get a shim in there to centre it. I did manage to get a thin piece of paper in there but was curious as to how accurate applying a tone would be. It seemed to work very well. Thanks Don 🙂
Hello Dave ,Tony from the Uk . What is press board ? Great video as always .
Hi Tony. Pressboard insulation material is used under switchboards or anywhere mains voltage needs to be isolated from another material. It's rated at 150C and a dielectric strength of 12kV/mm. Our local electronics shop sells it. It's much the same as Presspahn Paper. Thanks Tony 🙂
👌👌👌👍👍👍
👍👍👍😊😊😊
Has a lathe, media blaster, and 3D printer to bring to bear on a radio (and make custom tools for it), and still calls the effort "amateurish". Well, there's no hope for me then!
Haha... thanks Lurker 😅
Amateur effort! I don't think so. That frame came up very well. Looking forward to you weaving your magic on the case.
Thanks Ian, The case on Friday 👍🙂
🤨 - as another CZcams’er that wears a respirator when using a “supposedly” sealed sand-blasting cabinet, the connected dust extractor has poor filtration and blowing some of the finer dust back out 🫢⚠️, the room it is in, is poorly ventilated?
Hello Samuel, The cabinet is connected to a vacuum source via a coarse and two fine filters. The the outlet from the extractor is vented outside. I wear a respirator as well 🙂
Another great episode. As always. Best of everything to you and yours!
Thank you Midnight 🙂
I knew that you could fix the speaker. Waiting for part three. Have a good weekend.
Thank you Stanley 🙂
