Roberts DAB radio repair

Mark fixes a dead Roberts RD60 DAB radio. Fiddly Power Supply fix, and a dead amplifier chip are all it needs!

I'm watching this in 2024. OMG switching regulator shortage nearly put us out of business in 2022. I wound up making 3 different version of our PCB to accommodate what we could get a hold of. That upside down chip bodging is call dead roaching her in the states. Thanks for the video Mark

Man, you repaired a product that was never meant to be repaired! That takes real skill! Awesome!

[mrx.]

Mark is always smiling. Enjoy watching you buddy. I have a laugh every now and then when you animate the repair process with a little sarcasm.

Clicked on one of his videos a week ago, and now it's like a daily soap opera !!! This guy has some serious serious test equipment !!

I've never heard anyone but my late mother say "It's the way you hold your Thanks for the memory!!

I'm not interested in electronics repair, soldering or circuit plans at all.
But watching you work (from Germany, by the way) with your positive attitude, patience and love for the challenge brings me in a good mood. (Excuse my bad English, but I think you'll understand.)
I wish you the best, sir.

Build quality is outstanding, comparing it to some £25, 000 Pre-Amps ;)

Seeing the Roberts Radio takes me back to when I found an immaculate tan-coloured one of these on a Council Tip in 1966. Obviously not DAB back then! My father was much like yourself, and he quickly diagnosed why the Roberts didn't work. He also got the Oscilloscope out! Even though 57 years have passed, I still remember that the radio had a faulty Oscillator Coil, and this was a Weyrad P50 /1AC. Coil was replaced, and I'm sure that it didn't fail again. I moved from the UK to Australia, it "got lost" in transit. I am always amazed at how easy you can fix almost anything electronic. This has been a lifetimes' hobby for me, and I "have a go". If I exhaust my knowledge, and cannot fix anything, it goes to the Tip. You need an Apprentice!!

Markyou amaze me how you tear into these things like you actually engineered them. You definitely listened in class.😂😂😂. You are an electronics genius.

I've seen many of Mark's excellent videos. But this is by far the most insane and impressive one. I got the shivers by only watching it. Mark's sheer dedication is absolutely mindblowing.

Just want to say thankyou for the video, found it when i was working on my Mums RD60 where she had used the wrong power supply and blown not only IC11 but IC8 and the amp IC4. i used your method of mounting a LM3475MF Upside down and changing the Feedback network resistor. working perfectly again now :)

[midinotes]

Loved how the saddest piece of music in history (Adagio for Strings) started playing when you fixed the power amp! That was a very impressive fix and requiring the patience of a Saint. Top work Mark! 😊

[ReinhardLahusen-rbxs]

Best what ever I have seen ! Iam from Germany und my English is not good, but Marc is the Best of World electronic Man !!! Thankyou for many Videos !!!

[groovethaang]

Thanks so much for this Mark. Some friends gave me theirs, which was also DOA. Your video saved me quite a bit of time diagnosing that buck converter. It remains to be seen whether the Class D amp has also failed, but I’m ordering the chip from Digi-key, just in case.

Really glad i stumbled across this channel. It all goes over my head, yet strangely compelling !

[Jaycobson]

I'm not into electronics, but you take us on a journey with your videos. Brilliant entertainment 🎉

When you clean with that paper.. God it reminds me of 1970s school toilet paper!

[drummerhammar]

Unbelievable! soldering that small ic took some skills! Great work Mark!

[judyfay]

Your knowledge is awesome! How many people could do what you can do these, ‘throw away days’? I’ll bet not many! Fantastic.

[theprior]

Well you know what you're doing as it's second natiure to a seasoned electronics engineer but to anyone not versed in that medium it's pure witchcraft. I would never remember where any of it went when putting it back together so watching this is just awesome.
