- When I fixed the AEG radio, I added a speaker output, remember?
Well, it's time to fix a speaker to plug into that output!
Jänseidsmäßig Thanks to Richard for GIVING the Speaker to me!
Many thanks to Daniel - he GAVE me the cloth-covered cables.
Enjoy!
Nice work. We Model A and radio collectors appreciate your devotion. Keep up the good work.
Paul Shinn must be very proud of you.
Adrian, thank you for posting this speaker rebuild...I enjoy your electronic restorations...I always learn some "tips" that help me with my own non-Model A projects.
Your friend seems to have a lifetime’s supply of radios for you to fix. I see much more cabinet sanding and rat poop in your future. Enjoy!
Yaay xD
In one simple word, “ fantastic job and results “ congrats 🍾 The Jacobs 🙏🤝
It's amazing how good the sound quality is from something that is almost a hundred years old
As usual, great fun to see your restoration process, and hear the nice results!! You’re the best.
Good work and perfect choosing of that version from the 1940s -50s of Rose Marie to proof the speaker!
Great restoration. 😊😊
You and I are kindred spirits!
Yes, I am in agreement with all the positive posts,. A fine addition to your very, very vintage (almost) HI-FI!
Nice job and bakelite is a pleasing material to handle & smell. Has a nice quality feel to it and is surprisingly durable.
However, a word of caution for future projects using bakelite, some contain asbestos, but is not readily identifiable, so best to assume that all old bakelite products are an asbestos containing material and treated as such, so no sanding, or if you really must, take precautions with proper PPE.
A good trick is to first stretch cloth on a thin wooden frame to make it taut and flat, then glue it into the cabinet. Then the wooden frame can be sliced away.
Nice. Now you have this one, you're ready to amplify some live rock concerts :)
Outstanding 👏👏👍😎
Very nice speaker and radio! I was wondering how you would fix the broken needle of the speaker. It sounds great! Thanks for the video!
very very nice...❤😉👍👍👍
Hi..👋🏻 Love your videos, both of your Ford A and the mopeds and everything in between, so cool to watch….speaking of watch(es), what are you wearing on your wrist in this video?🤓
During the first half, it's my grandpa's Seiko, the 2nd half it's a mechanical "Diehl Compact", probably 50s or 60s era.
Du bekommst die Oberfläche mit autopolitur hin.... Und hin und wieder mit babyöl
Nice restoration. The speaker cloth looks appropriate for the year.
I will be restoring a 1928 Radiola 18 in the near future.
What website can your direct me to that shows how to take apart and assemble an oval Model A speedometer?
Thanks
Here's a written description if you want to go all the way: modelahouse.com/tech/speedometer/fischer.html
Otherwise, there's a guy calles "Astra-Werke" on TH-cam that made a video refurbishing one of these ;)
Thanks. I will search for your video
Nice job on the restoration, how does it sound to you? How does it compare to the others?
It has a little less treble - sounds a little dull in comparison.
That may either be due to its age (speaker tech wasn't that evolved in 1930, after all), or due to the magnet getting a little weak - high frequencies would take more energy than low ones, I'd imagine.
Might also be my attempt at fixing the cone - who knows.
But all in all, I'm really surprised with the quality. I expected tinny, soddy sound from it, but you still get quite alot of detail out of it!
i just got my first old radio -- a 1930 Philco Model 20 -- and am hoping to restore it. Any tutorials or resources you'd recommend?
Take a look at M.Caldeira's Channel (Electronics Old and New) - he's going through all the steps in great detail.
@@AstraWerke thank you! i love your videos. super creative and educational!
Nice, but you should have stretched the cloth, perhaps by mounting it on a frame?
I've had bad experiences with trying to stretch patterned cloth - it just distorts the shape weirdly.
I admit, just laying it on in some way doesn't look perfect either, but it's the best I can come up with..
@@AstraWerke Did you ever see how theese were mounted originally?
@@ferrochinabisleri1587 The perimeter around the cut-out pattern has a knurl-like pattern. The cloth was glued in place in that area. Sadly no evidence how they made sure it wasn't crooked
I finish Bakelite off with shoe polish.
1) Why didn't you soak it a few days in hot soapy water?
2) I wish you would have shown the work that you fast forwarded through. That's the interesting part.
In hindsight, yes.
I suspect the bakelite might benefit from a lacquer coat; or (less permanently) a simple wax polish.
Could you tell me (everybody) more about the speaker drive design? It's so completely unlike a modern speaker! Everything's in the front, not the back!
It's really quite simple: Wedged between the horshoe magnet is the voicecoil - just a bunch of wire around a spool.
The fixture that clamps the spool in the magnet leaves a slot at each end of the spool, threaded through which is a thin metal strip.
Two feet are screwed onto the metal strip, they're soldered into a fork which transmits the vibrations from the strip onto the speaker.
Edit: Having written that down now makes it sound not simple at all xD
@@AstraWerke An article + PDF on old loudspeakers (leading to modern loud speakers) can be found by searching for:

(TH-cam won't let me post links!)
But he doesn't mention YOUR type of loudspeaker

A part of History ---- you ---- bring back to Life ------------ And we ----- Lose ---- part of History ---- today --------- Tony Bennett passes away at ninety -six ----------- Watched you put on an LP onto the record player ----- what do ---- you ---- use to clean your records? --- And noticed you used -- Brass Polish --- on the Bakelite ( plastic finish ) does that polish give it a different effect? ---- What does that do for it? ------ Enjoyed the video ------ You Take Care ---- Rodney
As far as cleaning records goes, I just gently scrub them with soapy water and a non-abrasive sponge.
Regarding the brass polish, I'll admit it's the only polish I have that actually does anything. My chrome polish is a joke and the paint polish is far too fine to do anything on plastic.
15:00 - do you also use "Hasde Lötfett"? It works fine and I love the smell. ;-)
A tin will last a lifetime and more - this one's from my grandpa xD
@@AstraWerke - I inherited mine from my father who bought it in the late 50's or early 60's ....
A purchase for multiple lifetimes. I wonder what has become of the original manufacturer?
@@relgeiz2 Well, I guess they sold their flux tins to everybody that needed one... And then discovered they had to wait multiple lifetimes in order to be able to sell their stuff again.
Be happy that this speaker system is not made from zinc like many of them are. They all get brittle and are nearly impossible to repair.
The bakelite has too much filling material and is already damaged too far. If you want it to be more shiny just clear coat it.
I'm not a fan of connecting one of these speakers to a radio as it always changes the load impedance on your output tube and moves the operating point. Even if the manufacturer made it this way it's often far from being ideal to use a radio that way…
I think I'll leave it the way it is - if it had some beautiful graining like the AEG, a clear-coat would be worth it, but the way it is right now is perfectly fine for my standards.
I understand your worries, but to be honest, I couldn't notice any difference in the radio's performance with or without the speaker attached.
Sehr schönes Ergebnis, hast du den Magnet noch mal nachmagnetisiert?
Der war überraschenderweise noch recht kräftig - und da ich im Nachmagnetisieren noch keinerlei Erfahrung habe, habe ich davon abgesehen.
@@AstraWerke Das ist einfach, einfach Super Magnet anlegen und der Stahlmagnet wird aufgefrischt.
@@pr191148 Mein Nachbar hat da nen alten großen Transformator, wo er einseitig den Kern geöffnet hat. Da gibts dann einmal kurz ordentlich Strom aus 2 LKW-Batterien, und dann "leuchtet" der Magnet wieder. Nimmt er zum aufmagnetisieren von alten Zündmagnet. Den von meinem alten Deutz Standmotor hat er so auch wieder belebt!
devo is alive and well in this video ! are we not men ?
I'm afraid you'll have to elaborate on that one for me..
