Parts or Repair? - Philips AL990 Shortwave Radio

[@Techmoan]

*There’s a bit more information about this in the video description text box.*

[@rokokoko123]

I am really curious why PSU is not working. Try measuring resistance of transformer, it is blown if it reads open circuit or very high res. If it displays somwhere under 200ohms, diode rectifier is gone

[@Techmoan]

You’ll have to remain curious. I’m not interested in finding out why a feature I don’t want to use isn’t working. There are far better things to spend my time on - like the next video.

[@AlexKworld]

Would like to say this is one of my favorite videos of yours. The thought of these old beasts winding up in a landfill cause it needed batteries is just plain sad. Besides, the process of personally rescuing & restoring a piece of kit like this is so much more rewarding than buying a perfect "New In Box" specimen for 10x the price. Well done!

[@TomRuzanski]

This deserves a revisit. You have loads of experience repairing things now lol

[@Kevin_Carlson]

Having lived more than half my life in South America, I've always loved shortwave radio. There's not as many stations to listen to now days, but I still have several receivers. So great that you were able to revive this radio.

[@mistermatix8241]

Love these old world band shortwave radios! To me, they're almost akin to a geeky adult version of a Fisher Price Activity Centre! Knobs to turn, levers to flip, buttons to push, meters to gaze at, lights to turn on and off, you get my drift! When I was younger, my dad had one very similar (don't remember the manufacturer, I doubt it was Philips, as dad wasn't a fan of their products, as we'd had bad experience with Philips kit) but it packed in, and was deemed too expensive to repair, but I just loved playing with the chunky levers, and messing about with it, maybe that's why I'm a big techy now! Just thinking, it could have been Sharp, Sony or Panasonic. It's quite nostalgic for me, as my dad passed away 10 years ago. That radio, he didn't like anyone messing with it, but when it failed, I said I'd like it, and he gave it to me, yes it didn't work, but it was like a holy grail. I just had it as something "cool" in my room, as it was immaculate. Happy memories...... Embarrassing fact: me and my mates Michael and Ian were big scifi fans, and I'm sure we made a scifi film using dad's Sony betamax video camera, and used the broken radio, my brothers Sanyo boombox, and and Michael's Atari 2600 as a control console (yes we were into tech) I'm still mates with Michael and Ian, and yes we still love scifi, and reminisce about Logan's Run, Silent Running and the like down the pub!

[@624radicalham]

@kristopher hewitt The big blowtorch 1 million watt stations are gone, absolutely. What this allows, if a person likes the hobby, is for one to experiment with bigger and bigger antennas and angles to see what you can catch on the other side of the world. Changing antenna angles and such is very rewarding, like fishing. It's a sport and in many cases a competition sport. Check out channels like Oxford Shortwave and Senderyaeger and have a look at the amount of stations these people catch on a competition basis everyday.

[@erikgstewart]

Are there still number stations out there?

[@jtmichaelson]

Outstanding work. I used to tinker with shortwave as a kid in the late 70s and early 80s. It was a lot of fun getting British radio stations and learning your "language", as it were.

[@gtoger]

This video makes me appreciate my Panasonic RF-2200 which has been collecting dust under my desk all this time. I've managed to lose the battery compartment door somewhere...

[@sclerismockrey8506]

The RF2200 is my absolute favorite MW receiver ever. As a standalone portable with batteries and that Gyroantenna and that big air variable tuning capacitor, the RF2200 is just the best single AM rig I own. Sure, I can usually dig out more DX with phased antennas on a big tabletop rxer but that requires a bunch of gear and outdoor antennas. For just grabbing a radio and listening for longhaul, interesting analog AM stations, nothing beats the RF2200.

[@qwertykeyboard5901]

​@@sclerismockrey8506I really like my rx-fm45. That thing is pretty damn good on AM! I also have this Sears "automatic radio" thing that's on par with the Panasonic. It has three IF stages.

[@twocvbloke]

I've had radios in the past that had an alarm function, and they didn't work unless the radio was on mains, so not really a fault, just a symptom of the dead mains side... :)

[@therealjammit]

A glance at the schematic does show the alarm will work on batteries, external 12v, or AC mains. I had the same thought at first.

I'm 65 years old, and back in Junior High School, grade 7,8, and 9, I took an electronics class, and I would repair old tube radios.

This is the kind of thing I'd have really liked to have had when I was working in the Middle East 40 years back - Before the net, SW radio was a very important source of news and entertainment for us expats. Happy memories of sitting on top of the car in the desert at night to catch the BBC World Service news! Seems to be a lot less stuff on the SW bands these days, or maybe its just my cheap old SW radio.

[@DJTKarlsson]

there is some good stuff still out there, short-wave info will help you out easy

[@highpath4776]

Grundig Yatch Boy and similar are good, some come with cassette deck too.

[@goishikaiganmademou]

Nowadays you'll get internet radio from anywhere in the world with FM sound quality. That's probably why so many MW and SW stations have closed down.

[@rosshilton]

frglee Dubai 1978 - 1979. BBC World Service, news, cricket, football results. I can still recall the BBC fading in and out, the hiss and the crackle. A scary bit in February 1979 when the Shah of Iran fell. Only about 100 miles across the Gulf. We were glued to the radio in case war broke out. Where were you mate?

[@skateboarding118]

There is still shortwave though, despite there not being as much as in the past. It’s like fishing, there are good days and bad days! You can get a Tecsun receiver with tons of features and great sensitivity/selectivity for cheap nowadays. Even add a wire antenna and it’s a ton of fun!

[@benters3509]

As an ex MN Radio Officer, this would have been useful back in the day. I notice you have a BFO (Beat Frequency Oscillator) that makes the reception of morse code more user friendly! Whether the radio is any good for this purpose really depends on its sensitivity and the precision of the tuning. One ship I was on, our Chief Engineer had a Sharp portable world wide radio that had extensive short wave capability. He could pull in the BBC World Service in his cabin with a small external antenna sticking out of the porthole, where I was struggling with my professional setup in the radio room. I always wanted one of those radios. I saw one for sale on e-bay a few weeks ago, but did not buy it. I am trying to downsize my life.

[@Fatgerman]

Wow this brought back some memories. When I was a kid and we used to visit my uncle, I'd sleep in his "study" where there was a SW radio. (I think he was a ham operator but I'm not sure). He had an enormous aerial mounted outside and on good days you could hear people on the other side of the world. To my young mind it was absolute magic. There was a guy we could occasionally pick up who did a morning weather report every day from his house in Australia (I'm in the UK). I still think about him. These days you can "hear" anybody anywhere just by opening an app on your phone, but it doesn't have the magic of carefully tuning it in and actually hearing someone's voice.

[@MadBiker-vj5qj]

Due to the fact that it did not work on the 12v input I would suspect something other than the transformer... it's more likely to be a voltage regulator on the supply board. To check the transformer bleep out the windings for continuity.

[@beware_the_moose]

I actually thought maybe the secondary coil may have fused to a short, which would take the 12v input to a short too if it's wired that way. Just an idea anyway!

[@Muzer0]

@@beware_the_moose So disconnecting the transformer completely would maybe make the 12V work if that theory is accurate...

[@alain99v6]

sending twice the voltage on the primary would of course make the seconday ouputtuing twice the voltage, probably right about voltage regulator but maybe also capacitors if they were rated like 16V or 25V at the output of the rectifier

[@Lucien86]

I would definitely guess the main voltage regulator blown.. but it works off batteries so its (this is) a bit of a mystery. Maybe there's a primary regulator that took the heat. The transformer will prob be okay but the 4 way rectifier(s) might have blown.. The rectifier would stop a short circuit in the transformer from pulling the 12v line down so something else is blown.. Probably a few dead caps too.

If someone hasn't already suggested. The transformer may have a in-wind fuse hidden under a few layers of wrap. I have repaired several transformers by replacing that fuse. It will be on the primary (Input) winding and is usually a fiber insulator with a tiny piece of wire across it. Good luck.

[@GraemeRobinson]

Brings back some great memories. Great video.

[@Robb403]

A very enjoyable video. When you have a little time and with some patience, you may be able to repair the transformer. Since it isn't smoked, a conductor has probably opened up in the transformer or more likely on the board. You just have to track it it down. Also, make sure that the replacement fuse is the right size since some people fix a blown fuse with a bigger fuse.....

[@justanotherfreakinchannel9069]

The radio switch and the alarm switch are the ones you replaced. They're very close in color to the originals, but if you pause at about 11:19 you can see that at the right angle the new replacement backings are just slightly more glossy.

Set alarm time Push alarm (38). Push store (40). The alarm time will disappear. Indicator alarm (54) blinks. When (40) isn't pushed in 5 seconds after (38) was pushed, the local time will reappear. Set the prefered alarmtime (see setting the clock). Store the alarm time in the memory with te start button S/S (38). Alarm Choose alarm function SK-E (26). Choose alarm 1 or 2 (35) local time or second time. Switch lever radio/clock SKG (30) in the clock position. The loudness depends on the position of the volume button (3311). The alarm can be switch off by: a) Puting the switch radio/clock SK-G (20) in the middle. b) The touch contacts (44). The alarm will repeat in 24 hours. c) The alarm switch SK-E (26) switched off.

A lot of the OLD military radios had bars and things to help protect them from the abuse they were sure to get, so it transferred over to the portable short wave radios made much later. Besides many listeners started out with military surplus radios and stepped up as life got better and they had money to upgrade and it made the radios look similar and built to take abuse.

Fascinating. I have great memories of being a kid listening to my ITT Combat radio in my bedroom and finding stations from other countries. It was a magical experience.

WOW! Trip down memory lane!! Used to have this exact radio.... a long time ago in the 80s... loved that unit!! Thanks!!👍🏻👍🏻

Battery only? An easy way around this is to add up the voltages of the batteries, then get a power adapter that makes that voltage, hook it to the positive and negative terminals of the battery compartment. Maybe solder in a jack so it could be unplugged too.

[@krzysztofczarnecki8238]

Or use the existing socket, just disconnect it from the board and change the label to the right voltage. I definitely wouldn't use a switching supply though, as that would most likely completely ruin the reception. And the transformer is probably ok and this is somewhere later on in the power supply, like the regulator. Making a simple linear regulator power supply with the existing transformer would be easy if it works (schematics anywhere online, look at LM317 or L7812), and the trafo can be checked with an ohmmeter. If the primary and secondary show continuity then it is probably ok. I say probably as I had one with shorted turns once, this can happen after mechanical injury or overheating. The voltage was ok at first, but then it started to smell and melt, so check if it doesn't get too hot after running for a while before putting it in the enclosure.

wow, what a gorgeous shortwave radio; you really lucked out! ☺️

Fascinating video and what a great job of refurbishing a device that can still be very useful for years to come!

[@DishNetworkDealerNEO]

The thermal fuse in the power transformer opens the primary return line! A heat sink must be used to solder in a replacement!

[@AndyHullMcPenguin]

More specifically, there is often a thermal fuse "hidden" in a small plastic pouch or taped under the plastic tab on these transformers, on the primary side. With a little careful surgery, you can usually replace it. This may be possible without affecting the look of the thing, or may involve some heat-shrink tubing and a little bit of a bodge, depending on the construction of the transformer. We used to have to do this from time to time, on a certain well known printer manufacturer's main transformers back in the day. In that particular case, the thermal fuse cost a couple of pennies, but the transformer was a bit of a beast, and cost an arm and a leg. The fault that caused the fuse to open also needs addressing, which in this case may be something on the secondary side, although you may be lucky, and it may simply be that the application of 240V to the device when it was configured for 110V was enough to rupture the fuse without any secondary damage.

Thanks Mat. I love it when somebody takes the back off something.
