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.

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

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..

I got sad when you said about the label on the back and years to ome... :( i was wondering wheather the alarm fucntion not working has soemthing to do with the alarm strip on top, it could be shorting? But shortwave is a little sad now days, not many left in the english speaking world.

Thankyou for your videos I really enjoy watching them!

This is the thing about electronics repair: You're going to have a device you love you'll patch it up as best you can but be unable to fix some things but after a year or two of learning more it becomes a project to come back to.

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.

12v connection you can direct it to battery lol

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

Nice video. You didn't show the BFO function used for Single Side Band reception. You can listen to Ham Radio or even Number Stations on this radio.

That's a smart looking piece of retro kit.
Hey bionic nan sound effect at the end.. Lol

It is shortwave, go outside in the early evening for more stations.

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

Very enjoyable video. I'm also quite a fan of those eighties shortwave radios. I was gifted a Yaesu FRG-7700 and all it needed was some attention to the power switch and a good clean!

Awesome! I'm born to love those types of 70s 80s radios :D and I hate FM sound: too purified! btw, if you like to watch an excellent repair for the sony crf 330k, check ou mr carlson's lab channel! lots of electronic education! Besides the Description is precious :p

When there was something to hear.

I wonder what there is to hear on shortwave anymore. Most English-language broadcasting for North America stopped a few years ago.

Well, looks like we've came to times when thing without batteries is considered broken. I wonder when people will start explaining electric devices by a processes of magical nature, since harry potter is being the only book they read nowadays.

i couldnt imagine his insurance on his collection .

I know you don’t want to fix it, but if you do I’d check to see if you are getting an AC voltage out of the power transformer and continue through the circuit checking a dc voltage at the rectifier and voltage regulator both of which should appear in the service manual schematic

Years ago a friend of mine learnt Russian listening to shortwave radio broadcasts. The trouble is few Russians can understand him all the time as he goes in and out of tune...
