Parts or Repair? - Philips AL990 Shortwave Radio

  • čas přidán 8. 06. 2019
  • If something is broken there’s little to lose but much to gain by attempting a repair - even when I don’t have a clue what I’m doing.
    INFO:
    • I don’t want to plug this into power - so it’s fine that this part doesn’t work.
    • I don’t need to use the alarm - so it’s fine that this doesn’t work.
    • I used electrical insulation tape on the soldered wires as I couldn’t find my bag of heat shrink tubing.
    • It uses 6 C-Cell batteries - the red battery release ribbon is looped behind the rear two batteries, so one pull of the tape releases all the batteries.
    • I checked the polarity of the 12V DC plug by reading the service manual before I plugged by adaptor in
    • This is not my first rodeo
    • Try to just enjoy things as they come - it’s more fun than looking for holes in them. It’s a simple video about an old radio that just needed new batteries.I’m really not trying to fool anyone here - these types of videos take a long time to shoot but then are edited down to the highlights. Just like watching a 30 minute TV show where someone builds a house - you are seeing selected highlights - a house takes more than 22 minutes plus adverts to build and like that this video was spread over three days of shooting which accumulated about ten hours of video. If something isn’t shown in the videos it doesn’t necessarily mean I forgot it - I mean who in their right mind would leave bare wires pushed up against a circuit board - the suggestion is preposterous, of course I covered the wires...but no one really needs to see someone wrapping wires in insulation tape any more than they’d like to see me walking to the Amazon locker to pick up my aerial delivery or the hour long section where I tried to get both of the incredibly fiddly copper washers back into the new aerial.
    It’s just a video it’s not a challenge.

    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. I used a signal generator, and a signal tracer to find a faulty part. I would then tune the "cans" according to the manual and they worked great. It was a good hobby.

    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!

      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.

    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.

      @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.

    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.

    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.

    Being a HAM radio operator (although with currently no rig to be on the air), I also have a thing for shortwave receivers and communications receivers. I've got myself a Sony ICF-7600D (known as ICF-2002 in the US) and an ICF-2001 (not to be confused with the ICF-2001D). As far as I know, the 2001 was Sony's first SW receiver with a digital tuner, and even John Lennon had one :) (at least he was photographed with one)

    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
      @krzysztofczarnecki8238 Před 4 lety

      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.

    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.

      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.

    • @AndyHullMcPenguin
      @AndyHullMcPenguin Před 5 lety +1

      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.

    Well, i had a philips turntable with a blown transformer (it's a GA 212), the solution was simple: disconnect it by desoldering from the wires that connect to the board and solder them to a normal 12V external transformer plug (as that ones used to power external hard drives for example, i've used one of those). In my case the original transformer (very very similar to that in your video!) simply converted current to 12 volt, so i think this can be a cheap and quick solution to your "batteries only" problem.
