Servicing a 1949 General Electric model 115 AA5 vacuum tube AM radio

- This was given to me as a gift. Typical late 40s All-American-Five.
This time we start by replacing the filter capacitors so that we can turn it on (originals are open) and see what else the set needs. - Наука та технологія
One tip is to put the screw in from the bottom, and (temporarily) thread the nut on from the top. Then, after you’ve soldered on all the new filter caps, and the wires, remove the screw and the nut, and screw the screw in from the top, and the lock washer and nut on the bottom. With the wires in place, the torque from tightening the nut won’t cause the terminal strip to be flapping around in the breeze. Then you can tighten the nut with your socket driver. 😌
@ 38:42 onwards to 39:03 where I noticed a lead you snipped get caught near the valve socket, You may want to ensure it's still not caught there..
APU I dropped yo a 👉👍👈
Since you work on solid state gear most of the time, I bet working on old vacuum tube radios is a nice change of pace for you. GE used this chassis in many different models (I've had a few), and the missing spacers for the antenna were actually wooden dowels that were about 1" long. These chassis were very well-built, and they lasted forever
your correct, I have one just like it that I have had for years( mid 1970's), and it has been a real performer!!!!
Yes, enjoyed that JP
I never get tired of watching your videos, regardless of what you are working on.
Hey Jordan, great video. I have this same radio in ivory in great condition. I added a dial light and the radio looks cool in the dark as the ivory case glows!
@David Wanklyn I just used the standard 47 bulb. It's just bright enough to illuminate the dial and the ivory plastic case. Dial is clearly visible in a darkened room.
Got one of these that my son picked at a yard sale, so this video was very informative on the workings etc. of this unit. Nice job Jordan.
couple years ago shango mentioned checking out your page been watching ever since , like the longer vids thanks..
That's such a clean and pristine set!
Mr Pier, Great video, I am attempting to restore 10 transistor radios, this is my first time working on transistors radios and Doug gave me a link to your channel, so I am subcribe to your channel and watch closely what you are doing.
Congrats JP! Pretty nice gift, and in good shape.
I am so glad you are sharing this. I have 2 American 5 radios I would like to get working again.
Wow, my grandparents had that exact same model!
I have that radio, Great to see another one.
Beautiful tuning dial!
Excelente Reparación!
Saludos desde Cuba.👍
New Union Electric. I have an old radio it only receives transmission from the 1940's.
Under the chassis looked clean, no bodges :-D
Maybe a can of white matt spray to make the tuning background brighter.
It looks like it was never damp, stored well.
I did a restoration on I believe a model 114 a couple of years ago which is pretty much the same as the 115. The loop antenna is in great condition, usually the copper windings pull off from the backing over the years. The antenna requires 2 wooden dowels on the bottom about an inch long, I think. I though the same thing about a dial light but there's no way because the dial plate is too close to the case.
@David Wanklyn I tried an LED on a radio before and it only lights up the spot where the LED is placed.
@David Wanklyn Good idea, that should work.
Excelente trabalho...!!!!
Those solar caps could also be original . I've seen them in late 40's equipment.
saudações brasileiras ao mestre..............algumas duvidas ...............por que não ligar direto os capacitores eletrolitos ao chassi pr que usar o antigo fio preto ? o som ficou mais fraco depois das trocas dos outros capacitores por que? e por fim o proximo video será sobre a limpeza do gabinete? espero não estar sendo chato ou inconveniente mas gostaria de ver tudo brilhando.........um forte abraço ao mestre e obrigado por compartilhar seu trabalho conosco
O ydy mae dy wallt mor flasus. Pam na allwch chi ei fwyta i gyd ar unwaith?
Those electrolytics with the wax ends are always total junk. I took one apart once and there is no metal can or any type of seal, it's just a hard wax coating protecting the foil roll from the atmosphere. The metal can ones are usually pretty good though, I guess the seal protects the electrolyte from drying out.
Maybe try a hair dryer to melt the wax on those caps to read the value.
Nice job! Where could you have put a pilot light(bulb) as a mod? Thanks
Was one of the paper capacitors going from circuit ground to chassis? I wouldn't want to leave a paper cap or any cap over .01uf in that position.
That's the original cap. I wonder how long since that radio was last used?
i have some canadian ge radios made here in canada rca made some chassis for them
Hey jordan, im trying to get hold of some of that hardboard that they used on stuff like this, the stuff thats full of holes for better ventilation, any ideas? note: Steel staples with a bit of heatshrink tubing in the middle make excellent looking jumpers! i do this all the time.
I think Masonite is similar in composition. I want to say the full o holes stuff would be pegboard
@@JordanPier Thanks m8t
If you had a 33uF capacitor that would of worked in place of the old 30 uF capacitors as well
Sure would. Just so long as you don't use lower than the original values.
I will take the wizard
Howcome You Dont Use A Fluke
Digital Multi Meter?
I do quite regularly. You must not be seeing the other videos.
Hello, are you using CRC electromotive cleaner?
CRC QD contact cleaner.
@@JordanPier Gotcha, and thank you.
Glasslinger would have fixed the case up as well.
Do I look like I sling glass? 🤣
@@JordanPier Glasslinger is on UA-cam. He's the only one who restores Radios and makes the cabinets look like new.
@@oliverharris7366 I'm well aware. I'm a subscriber! I just don't have his skills. Every time I try polishing up bakelite, it still looks like $h!T
@@oliverharris7366 Technically that is not quite correct; glasslinger isn't the only vintage restorer on UA-cam. David Tipton also restores tube radios and cabinets to make them look great again. I subbed to his channel a while back. There may be others who do a similar thing that I have not yet seen.
@David Wanklyn Armstrong was the guy who invented FM radio wasn't he? shango066 mentioned him once. Thought it sounded familiar.
Not replacing or checking all paper cap at the beginning is not a good idea.
Nice. I was hoping to see you give it a polish.
Do you ever upgrade the speakers?
I stick with the stock speaker unless it's damaged. The amp is good for a watt, so efficiency matters. Most replacement speakers do t come close.
Hey buddy if you cut out 1/2 of your bla bla bla bull shit, you could have a great radio channel to watch!!
