By 1979 more people started listening to FM than AM in the U.S., but as late as 1990 some cars and trucks still came with an AM-only radio as standard. This GE clock radio can be seen in the intro to the TV sitcom "Who's The Boss?".

Great video, my wife had a clock radio just like this one. Her brother gave it to her for Christmas in the mid 70's when her & I were dating. It lasted many years, this video brought back good memories. Thanks!

Just for a point of information, we got our first FM radio station in my home town back 3 years ago. It sure made things nice for mom, who is 97 and in the nursing home, she loves her radio but the AM was filled with static so now we tune in the FM for her and she can again keep in touch with our local news.

I have that same exact GE clock radio model too. The one that I have originally came from my mom (which she had it since it was new back in the 70s). Since this exact model that I have only has an AM tuner, we normally used it as an analog clock in our laundry room (we normally didn't have the alarm set and rarely used the radio on this thing anyway). It's still a nice basic analog clock radio. I just love these old clock radios like these.

There's also a date code stamped on the Telechron clock rotor you could use to get an idea of year of production. It's year (1 digit), month (1 or 2 digits), and decade (1 digit). There's more info on this if you Google "Telechron rotor date code". One of the best clock movements ever made. If it ever runs noisy or starts to lose time, you can also draw new light synthetic oil into those sealed rotors. One method is to use heat (such as with a light bulb) to build pressure inside the rotor that will then create a vacuum when it cools down to suck the oil in around the pinion. The method I like to use is to draw a vacuum by placing the entire rotor into a large syringe with the tip plugged, then quickly remove it from the syringe, place a drop of oil at the pinion, and either let it draw the oil in itself, or place it back in the syringe and use pressure to force the oil in. I repeat that process a few times. There's some good read-ups on this if you do a bit of Googling.

Those are terrific radios 📻. So are those GE clock ⏰ radio 📻. The only kind of those I’ve seen, were AM/FM. The GE clock radio my mother 👩 had was from around 1975-1976. I saw it in 1977, at her apartment in Fairbanks, Alaska. Just be VERY careful working in the backs of these. 120 volts is actually worse to be shocked 😳 by than 220, because ya cannot let go.

I that was one of GE's very low end clock radios. That being said they do seem to work good as I have that same one you got. I noticed that the covers over the volume and tunning nobe are missing which is a common thing as the glue that was used would fail. Also this clock was used as a prop in the 1989 move Little Monsters.

I'm the UK, where it's 240VAC, and I don't think we ever had those live chassis transistor radios here. Maybe because too much dropper would be required? And so the ones I seen always had a step-down transformer in them. I know we had live chassis valve radios though.

A little noisy at times Lol

Maybe that coiled trace on the PCB was a way of fusing the mains so if something goes wrong it blows the trace? I've seen other electronics where they did this as it's cheaper than a glass fuse.

@@12voltvids More likely just a easter egg the PCB layout person left in there, as it would not affect operation, and also would not actually use any space on the board either. Voltage regulation is likely done by the output stage, as they probably bias it to be a fixed current, so the current draw was selected to give around 15-20VDC across the power supply rail. Likely there is a zener diode for the LO stage and IF stages, as those will drift with voltage, and output stage bias is derived from there.

You are lucky the synchronous motor still works. Far too many have failed. Sounds pretty good for such a small radio. I have a Realistic Stereo from 1984 and the power cord wires go to wire wrap pins so you have these little pins sticking up with full AC volts on them. Pretty common back then, and a bit scary.

@@12voltvids I've been working on this stuff for a long time and I'm very careful. Still seems a bit crazy that they used to do things that way. I am concerned for the unwary who might be hurt by them. I saved the On/off switch on that 1984 Realistic stereo, which had welded itself together, by installing a relay. Had to un-weld the contacts but it now works great. As you know, certain parts for things like this are not available.

@@macgvrs yes I'm fully aware of the parts problem. I have been working on electronics now for a little over 50 years. Started when I was about eight or nine years old hanging out at old Al Mallatt house. He was the local TV repair man and his house believe it or not is directly across the street from where I live now. Yes I grew up in the neighbourhood a couple blocks away. I was a friend of the family and I got to hang out at his place and learn how to fix radios when I was very young. I worked at local TV repair shop when I was in high school but never plan to go down that road. I kind of fell into the business and did it for 20 years as a living. the past 20 years have been taking on projects at home so I've never really left the business so over 50 years I've been in this line of work.

I'm shocked that the caps are still ok, maybe the ripple was low because the radio is very low in current. A transformer would have been nice for a level of isolation, now it would have to have one for safety now. Is your lighting creating the radio noise?, it didn't sound like the mains. I like the way the tuning string and poly cap were keyed, easy pcb removal 😀
