Those postwar AA5 radios were inexpensive and durable, and despite their reputation as low-end receivers, as long as you put in replacement components of the same values as the originals, they'll work quite solidly and reliably! It's amazing to me that they dominated the home receiver market for 35 years!

GE also made the model 535, an AA6 (6 tube) clock radio. Note that shango066's radio is designated to be a "radio alarm clock." The model 535 was a "radio clock". In the early days of adding an electric alarm clock to a radio, providing the "wake to music" feature, apparently the industry hadn't settled on the name "clock radio" (making "clock" the adjective, instead of "radio"), which we use today. The GE model 535 was similar. It did not have the third section in the variable tuning capacitor, which some AA6 radios had. I acquired a hand me down GE model 535 when I was in my early teens, repaired it, and kept it running until I graduated from college. I am quite sure that it suffered silver mica disease. I didn't know what was going on, so, when all else had failed, I replaced the IF transformers with those from a junk radio and got my model 535 running again. Briefly in the video at about 5:21, we see that the B+ feeds to a tap on the audio output transformer primary. One primary winding lead goes to the plate of the audio output tube. The other goes to a 1K resistor and from it to the second filter capacitor, providing B+ for the other tubes. The DC in the two sections of the primary provide partially cancelling DC magnetic flux, allowing GE to use a physically smaller audio output transformer. (Too much DC magnetic flux will saturate the core. Designers use a core with an air gap and also use enough metal to handle the flux.) The downside of this strategy is that some of the output signal power is delivered to the 1K resistor instead of the speaker. If the audio output transformer requires replacement and you only have a transformer without a tap (scavenged from another radio), tie the tap connection and the 1K resistor connection together.

710 WOR here in NYC shut off HD Radio a while ago, ironic as that was the only AM station I could consistantly lock and listen to in HD. I also hear that WCBS 880 turns it off during their Yankees game broadcasts, I hope it goes away forever as it kills any chance of DXing WLS 890 here. Despite being a clear channel, I rarely can get a lock on its HD signal 30 miles from their transmitter. HD Radio will likely stick around on FM, it seems to work fine there.

FM stations have a much wider bandwidth to start with, and a larger separation between each station then on AM broadcasts, not to mention the much shorter range, so interference isn't as much of an issue as with AM. Even before the H.D fiasco started FM stations used their sidebands to multiplex stereo, SCA, and even Muzak broadcasts.

Actually, the metal "donuts" covered a set of 8 "wells" surrounding each of the 7 pin tubes, 7 for connection to the tube pins and an 8th tie point. GE called this their "mechanized chassis." It was a forerunner of the printed circuit board. About 13:48 into the video, shango066 shows a good view from the bottom. Assemblers installed components with leads stuck into the wells. In a later manufacturing step, the chassis was moved over a pool of molten solder with the wells in the solder. Solder soaked up into the wells to provide the solder joint connections. There were also "terminal strips", a set of wells in line, used as connection points. The "donut" and the "terminal strip" covers were added later, preventing objects poked through the back of the radio from contacting the circuitry. Note that some connections were still hand soldered, such as those to the IF transformers and the volume control. The "donuts" were nice for the serviceman. Just place the tube in the hole and twist it until the pins lined up with the holes in the socket, then push down into place. GE also used the "mechanized chassis" for some of its 1950s TV sets. The TV set wells were not covered. Zenith appears to have adopted GE's "mechanized chassis" for its TV sets and used it through the 1960s, long after other manufacturers were using printed circuit boards. Zenith called its products "hand crafted." Later, Zenith did adopt printed circuit boards.

Interesting point and I agree. If switching off analog radio doesn't free up a chunk of bandwidth the fcc will never bother. And since HD radio uses the same chunk of spectrum they would have to not only replace the analog tech they would have to replace HD radio too. I doubt that will happen anytime soon.

Excellent. I assume when your mentioned digital I assume you mean DRM digital radio Mondial. I am a ham radio operator in Northern England & I tapped one of my transceivers 12 kHz IF & I feed that into my PC sound card & use decoding software called DREAM which also displays text. It's possible to have 4 stereo channels or data mix text for news for example & it fits on a single standard AM channel. It's even possible to send a low definition TV picture. I only get DRM on shortwave as on our AM band 531 to 1602 kHz in 9 kHz steps it's just analog. DRM sounds great & with no fading or QSB signal, it stays the same level regardless of signal strength but will start echoing & break up when the signal is below the threshold. Our AM band gets swamped at night with Spanish stations. Very little elsse.

Also, why not replace that ratty old speaker, especially since the voice coil /bakelite ring it's mounted on keeps banging into the spider? I'm guessing the freq response of that thing is barely 150 Hz - 4 KHz (i know AM audio is very bandwidth limited, but still...)

Shango, I remember some time ago, someone asked if SMD was caused by the electrostatic field across the capacitor. I.e., would NOS IF cans from 50 or 60 years ago have SMD? I don't recall if there was ever an answer. If it's caused by the electrostatic filed, it seems that only the capacitor on the primary side would need to be replaced, since there is next to no voltage across the secondary. In one of your videos, you show sparking under the can. Was that on both sides, or just the primary side?

Norway is first country to start switching off FM Radio and going over completely to Digital Audio Broadcasting (DAB) completed nationwide by Dec. 13, 2017. Given the size of the country - with its mountains and fjords - and its small population, it is particularly expensive to offer both FM and digital audio broadcasting, it would save180 million kroner a year, or about $25 million in operation cost.

I see what they are for now, this set uses tube sockets similar to those used in Zenith TVs where the solder joints are made inside of posts around the perimeter of each tube.
