Parts or Repair? - Philips AL990 Shortwave Radio

  • Published on Jun 9, 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.
    • 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.

      @Roko Žilić Many of these small transformers have a small thermal fuse under the insulation around the windings.

      You made some points there in the video description.... if common sense were to reign, you wouldn't have to worry about explaining the obvious. Lol..

    When you soldered those wires to extend them (instead of replacing them) did you insulate the solder joints? If you did, you didn't show that. I hope nobody copies that.

    At 5:57 I gasped with delight when I saw that control panel open up. I miss having little hideaway things like that in this day and age, they're so swanky but so hard to find!

    There's nothing to listen to on all radio and short wave is the worse of it even as you wouldn't think that. All radio is controlled by the world guverRnmt.. totally, you would think we are in the middle of ww2 with spy's on every block or that the thousands of available bands are flourishing so much with billions of listeners that any interference is likely to bring down the economy...ALL FULL BuLLSHIttttttttf .... As a useful devise it belongs in the garbage CAN UNDER THE TELIVSION , NEWSPAPERS MAGAZINES BOOKS AND MOVIES

    I have a Kenwood TS-820S HF radio station with a similar arrangement... the frequency counter is a completely separate part from the radio itself. The counter doesn't really work right on mine especially before it warms up a bit, but the radio itself works fine.

    Shortwave receiver? Why not take the time to become an amateur radio operator, then you can transmit shortwave!

    • Scleris Mockrey

      What do you mean "Shortwave receiver?"...? Is there something surprising or questionable or wrong with him using a shortwave receiver? What a silly comment. You might as well ask him why he doesn't get a commercial broadcasting license for MW or FM instead of simply listening to and enjoying any of his other radios. I am sure he knows all about ham radio and would take the time to become licensed if he wanted to. What a weird question to ask someone simply enjoying a receiver. "Television? Why not become the owner of your own commercial TV station?"

    It would be simple job to wire in a DC mains supply via those battery terminals.

    Another amazing receiver from Philips, from the good old days when Philips designed good appliances and made them in Europe. Goddbye Philips, well done, Techmoan.

    The red ribbon in the battery compartment is to make it easy to pull out the D-cells, and thus should be behind them. I notice you had it on top.

    Wow, that;s a nice looking bit of kit and obviously built to last (possibly based on a military design). Maybe intended for the export market to places like Africa, rural Australia or South America where reception was patchy so you needed good quality components to get a decent signal. It also reminds me of the UHF radios when I was a kid at air shows when people would listen into what the pilots were saying. Anyway, another excellent and informative video, please keep them up

    Thank you for repairing all this old technology and keeping it alive! So much new technology only lasts a few years and ends up as worthless, disposable e-waste junk... and yet it's the "old" technology that can be repaired, and the "old" technology that lasts.

    How is this from July this year? Just popped up as suggested, and I thought "yeah, wanna watch that again, I recall it was really cool"... But it was like it was last year, or early 2019 in my mind. Am I going nuts?

    I came across something similar in a second-hand store back in the 90's. It was an early 80's Radio Shack brand that I got super cheap non-working. After nursing it back to life I was very happy with my purchase for several months. I left it in my car one hot summer day and found it had MELTED beyond use. Still kicking myself for that!

    Nice job on the repair. Nice radio too. I'd run a random wire off the nice to have antenna jacks. Could run it out the window and use a 22 gage magnet wire to keep it stealthy. With a little MFJ random wire tuner attached to the wire you could pick up plenty inside your house in spite of all the shielding. If you have local RF interference just go through your breaker panel one by one shutting them off to localize the noise source. I once found a wireless keyboard was the culprit. It had been placed on a closet shelf with a box on top depressing the keys and sending an unrelenting signal for several hundred feet.

    Just a thought - and notice I have NOT looked at the service manual - but if the mains supply doesn't work and the 12 v DC fails too - then I think it's unlikely to be the transformer as that certainly is not involved with the DC connection. My guess is - 220 v through transformer and then rectified into around 12V which is then regulated to the 9V needed for operations.

    Hi. I love your videos and It’s like a nostalgia for me to watch. I was doing a repair of that kind of equipment for 30 years.
    The transformer is good. The thermo fuse in the transformer is bad. It’s under the isolation tape on the high voltage section.

    Mr. Carlson's lab performed a repair on one almost like the Sony. Except it had no cassette player. It was the Sony CRF-320.
    What a design!

    Shortwave is dead more or less these days and there's very little on it. Many transmitters and radio stations have disappeared over the years. If Digital Radio Mondiale had taken off on MW SW and LW perhaps a bit more life would've been gleaned out of AM. It offered better quality over larger distances, was more robust at coping with difficult reception conditions and was a flexible means of broadcast at 1/3rd of the cost of AM.

    That’s funny because it’s junk, or at least no better than any amateur double conversion receiver today... except now it would be half the price, and have digital VFO.

    Lengthening those ariel wire leads introduces noise from circuirty next to where they are laying.

    The transformer has a fuse under a couple wraps of tape, for anyone who cares.

    Excellent content and production as usual. Taking old radios and record players apart as a kid led onto a life times interest and Mech Eng career. Apropos nothing, the buzzing and clicking, 16:20, reminds me of the 6 million dollar man.

    In 1978 I was living in Dubai. We had a similar radio in the kitchen, set to the BBC world service. we used it to get news and football results. Touching the tuning dial was forbidden!
    I can still close my eyes and hear the BBC fading in and out with background crackles and hiss.
    I Think the one in our kitchen was a Sony.

    Check your 12v socket. It has an integral switch. If that has failed you lose both the 12v feed and the mains derived DC.

    The reason they had an alarm was probably due to exact scheduled number stations or spy transmissions so a Soviet spy would set the alarm and the exact frequency and get his decoder
