"The World's Most Useful Radio!", some say, according to GE in 1951.
Let's go through it carefully and see if we can fix it.
This banged up radio was picked up in a box of 5 other trashed radios in similar or worse condition, mainly for parts. But just maybe we can get this one to not only work, but work well. Plus, it has a super power.
See the checklist which appears, when status changes, for tracking what is discovered that needs addressing in Red, followed by Green when resolved.
This is the first part of a video series on this radio. Please take a look at the Playlist for this radio where other parts will be listed as they are released. They will follow topics of the road to recover for this clock radio.
This is not instruction, it is for entertainment for people like me who enjoy watching projects and the experiences gained. If you attempt to do some of the things in this video you at your own risk. I am using special tech-bench safety equipment not detailed here so don't take for granted you can just plug these old items in safely without them being repaired correctly. Check out the link below to Mr Carlson's Lab video.

These are great radios and worth fixing. When restored they play quite well.

@jimnewman5596 Год назад

I was surprised at how well the speaker sounded. It was amazing that it worked at 75 volts.

@PracticallyFixed Год назад

Hi Jim, yes I was just as surprised. Too bad the case is in such bad shape. Thanks

Wow, this radio dates from the 1950's, and look at what few things you had to do to get it to work again. This thing was designed really well. They just don't make things like they used to !!

Interesting half torus shaped covers around the tubes. Wiring goes through holes in phenolic tube sockets underneath then soldered to tabs that go to each pin in the socket. All covered around the pins above and around. Believe I have a radio that isn't a GE that has such a chassis. I love your methodological approach to repairing an old radio. I'll be looking forward to the clock repair and see if you get it to work again.

Thanks! Mixing up the projects a bit due to the editing load I have. That video was recorded last summer, but haven't worked on it since due to the other projects which rolled in, and still need to finish the repair. Thanks again.

I've got the same model..and color. Complete with knobs. It's just waiting for me to go through.. I've got about 40 ahead of it. Lol. Biggest issue is the gold on the face is worn off partially. Debating on what is going to look best once I attempt to spruce it up. Thanks for posting!

@PracticallyFixed Год назад

Hi Paul and thanks. I guess we both Win. Yes mine has the same problem for sure. If you figure out what will work let me know LOL. (watch out for the radium though)

@hestheMaster Год назад

They make some great gold color paints in spray cans. You might have to find some at Hobby Lobby, a local hobby store, or another craft store as the average home improvement store doesn't carry anything other than Rustoleum spray cans. Then experiment spraying it on other scrap pieces of metal to see if it bonds good and you're happy with the color ( not too dark or too light).

@PracticallyFixed Год назад

The Hobby Lobby nearest me has only Krylon brand metallic spray paint. Will try some but I know it won't look like the cap.

@hestheMaster Год назад

@@PracticallyFixed A company called Tamiya makes some excellent spray lacquer paint. Look up their colors TS-21 Gold and TS-84 Metallic Gold. You may need to also buy their fine primer but if there is a lacquer finish on it already that must be removed first.

@garyk.8674 Год назад

I need to find one of these radios. I really like the clock

@PracticallyFixed Год назад

They made a bunch of them in various colors. Be aware of the radium. See Part 2 for demo. Thanks for the comment.

@garyk.8674 Год назад

@@PracticallyFixed I'v heard of radieum. Isn't that the reflective substance on the clock hands?

@PracticallyFixed Год назад

It's not reflective. It uses a fluorescing paint containing the radioactive element radium. The radioactive bombardment is what causes the fluorescing. There was a terrible situation about the women who worked painting dials known as the Radium Girls. See Part 2 here for a demonstration of the radioactivity. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HfRMyRWeTKc.html

@DERB_Seymour_Indiana Год назад

Hey PF. That radio is from the year of my birth so it must be really old. You may need to check your math, I will be 72 on my birthday this year. LOL You can't get rid of that speaker, it's holey. :)

@PracticallyFixed Год назад

LOL. And yes, I caught my math error in edit and added a note. I discover so many mistakes in what I say in edit...

@DERB_Seymour_Indiana Год назад

@@PracticallyFixed Ain't that the truth, been there, done that brother. LOL

@barryfleischer6553 Год назад

...I restored one.

@PracticallyFixed Год назад

Thanks, we will see how the clock does... Thanks for the comment.
