Grundig Trento Radiogram OP Transformer Replacement

My Grundig radiogram I restored in June 2021 had a bad output transformer, a wonderful man in Germany set about finding one for me, it finally arrived and I set about making it fit. He also sent me a radio built in communist Romania, I take a sneak peek at that too.

My digital Signal Generator:
The Signal Generator is a project kit from a local electronics magazine called Silicon Chip, there is a sister publication in the UK called Practical Electronics, it was featured in the April 2018 edition but mine has a oscilloscope function as well which I don't use. There may be a later edition in PE with that feature.

Sounds great Dave! Thanks for sharing the upgrade with us.

Thanks for another fine video...I'm always checking for the "blaupunkt" beside your name on YouTube...
The gifts from Blitz proves the fact that there are still wonderful people in this world...

I’ve seen all sorts of VU meters: LED, dixie tubes, magic eye tubes … but the balls of paper! The yellow ping-pong balls! Genius! I actually thought at first they were popcorn, and that you’d have a snack after the testing 😊

Lovely, just lovely. Will be looking forward to the Carmen2 too! All the best from the UK

A big round of applause for Mr. Blitz! Glad you got it sorted David and looking forward to the next one.

What a great thing! Blitz, if you're watching, much respect to you!

well done, Glenn Miller just sounds as it has to sound.

What a decent guy Blitz is. Really gives you a lift to know that people would go to all that trouble to help a fellow radio enthusiast out.

We are so resourceful these days with the Internet. 😁 It’s extremely valuable technology in these difficult times.

It was a very rewarding result with patience and team effort with that helpful conscientious gentleman from Germany. Hats off to him for being a team player in this radiogram project.

Although no FM, I am excited by opportunities to restore a quality shortwave receiver like this one day and get a descent shortwave antenna set up on my property permanently.

The shortwave experience with grandparents is a fond memory of this work.

Good demonstration of the transformer coils ratio Dave with useful diagrams. Thank you! 😁☕️

Thanks again for your help recently with the signal generator. The frequency counter arrived. I have pulled down the SG. It had been restored and the RF out put wiring for the FC was connected in directly at the rear of the RF selector.

Very clean inside but a piece of solder was removed from between the gang capacitor plates. I ran another clean in there too and adjusted the rubbing plates.

Looking forward to another radio adventure when possible. 😁👍🙋‍♂️

Dave, you truly are the "Grand Master" of radio repair! Thank you for all your help & I hope that you are feeling well. Cheerio!

[TheUltimateRecycler]

That's fantastic Dave! Great to see the job finished and what a very generous man Mr Blitz is!! Postage alone would have been terrifying!
I'll go and have a peak at his channel 👍😊

[BoBjjjjs]

Blitz is an amazing person. 😎👍 Good to see the radiogram up and running. 👍

[iantyler]

Just goes to show there are generous like minded techs with a passion for restoration all over the world. A great outcome for that radiogram. Lovely restoration as usual.

[petergleeson]

Good on you David. And to Blitz! Really epitomises the spirit of this great hobby. And another great piece of history preserved for the future.

[bfrieske]

What are the odds of finding a matched pair of transformers! Its wonderful to see that gorgeous console working. Great job! Cheers!

[ljetronic]

What an awesome community. The world is a small place, in some ways.

Mr Tipton, I always get excited when a notification comes through for a new video you’ve posted. I respect your knowledge so much, you’re a true craftsman! Thank you for keeping these coming through it all. Your work is definitely a bright spot in this unrecognizable time.

[wayneshirey]

Thanks for your generosity Herr Blitz. And thank you for the closure, Dave, and for the bits of big band music.

[joshuaboxer]

Great Work Dave as always. The vintage electronics community are a great bunch.

[opus]
