1982 Boom Box Repair (Telefunken CR100)

Mark repairs a Telefunken CR100 Ghetto Blaster, which has blown a fuse. The underlying cause requires some digging, and missing parts get re-manufactured on this 1980's classic.

But you are different, you just fix everything and restore them. Just love watching your videos and a subscription for you.

My grand father had the chance to get one of these bomboxes directly in Germany during the 80's, but the brand is 'Sound 4010'. It's basically the same but with some minor differences in the faceplate as well radio dial. Belt kit replacement and a nice clean, with also a Bluetooth small module, and it's back to life! It sounds amazing!

I pulled a "Mark" and ripped it all apart and noticed some solder joints, and I freshen them up, cleaned the connectors and then tested for a while. And wow. it was fixed. You're an inspiration, its amazing the level of detail, troubleshooting, and creativity you show in your repairs you share with us. Thank you.

    I had opened a lot of tv's, radios and other things in my younger days, and I always tried to find the thread in the plastic where the screws were. On a few occasions when a repaired item came back from factory, they did not do that, they made a new thread in the plastic, causing it to become brittle and would give away, breaking the screw from the plastic. This method I tried to bring to my apprentices over the years of network- and system administrator. Sometimes it is hard to see that not every repair guy or girl keeps track of threads for screws. Hope you do!

I also learned after a while that my capacity with a soldering iron was nil; I would solder all over the room, but none on the actual connection! While I wish I could do what you do, I can still watch and appreciate your efforts to bring electronics back to life.

    @philthehmk8752 Жыл бұрын

    Excellent work as always. Just a couple of points from my own point of view...I try to avoid cutting the print track to isolate chip pins. I always suck all the solder from the pin and its pad and then manipulate the pin to centralise it in its hole with forceps and/or a very small jewellers screwdriver so that it's not in electrical contact with the surrounding copper pad. I then solder a small wire to the actual pin and another to the nearest convenient solder pad to make a test connection. This saves marking/damaging the original print track and necessitating bridging repairs later. Regarding solder bridging on cut/broken print track, I tend to solder a a fine bus bar wire link across broken print track for mechanical strength - it's the way I was taught back in my C&G college course days. The fault clearing after removing and replacing the transistor is a strange one, as I couldn't spot any solder bridging as such, so it's just remotely possible that the transistor had a junction fault that was cleared when it was heated and manipulated when removed. I had a similar fault a few years ago with one of those back to back 3 legged varactor diodes in the FM tuner section of an old JVC boom box, where manipulating it cured the fault and it carried on working for years afterwards. Keep up the great work and excellently filmed and produced videos - you're one of the best!
