This has been quite a journey. It was a first for me, but I'm already looking forward to the next Zenith :)
The restoration would not be complete without the IF alignment of the FM, which is covered here.
Some creative re-build work was needed on the chassis, but that's what I really enjoy - finding solutions outside the box.
The final testing completes our project.
I hope you've enjoyed it, and that you'll join me for the next project.
Stay safe.

U tuning across the bands beings back memories when I was a kid experiencing DX for the first time.....in Riverside California...at night back in the 1970s with my first multi band..on BC later on SW ...then FM and TV... my first DX was on TV....we used to get Mexico and the Western part of the United States....than Cuba and The Bahamas...it was Cool 😎
👍
It sounds great. I need to repair and align mine.
👍
Ok big brother . Grazie manlio
👍
I have a 7000-1. It works, but has not been overhauled, yet. I really like the Zenith Transoceanic radios. They are indeed, ‘built like tanks.’
That 7000 will be even more satisfying when done.
Bravo para esas videos muy interesantes para los que tienen esa radio como yo. De momento no funcciona . Tengo que ver lo que pasa. El signal generator vale caro . Pero gracias por compartir tu sabiduria.
👍
Fast approaching 10K subscribers.
Yes, am getting ready to scare you all off :)
I don't scare easily.
Another interesting video. It is always good to see a radio designed with the service person in mind.
This one sure was 👍
This is really a work of art. You are very lucky to get it in your hand)
I agree. I’m looking forward to having another one to play with 😊
@@electronicsoldandnew I found same on local flea market for $150 in good shape. Even my wife says - buy it. I will think hard...
Listen to your wife!
You should try restoring a Royal 7000!
I’m looking forward to getting my hands on one. 😊
Good idea, to leave the linear powersupply inside. I like it too.
👍
Now that you have tuned her up Manuel , it really is a wonderful DX'ing radio. Now I need to learn 5 languages to understand what I'm hearing!
Yes, the languages are a challenge. 😊
When you were talking about "positive" ground with reference to the signal generator, I was just thinking there is no positive/negative when it comes to a sinewave and the signal should go to the Test Point and the shield still to ground, but it looks like it worked regardless.
Another great video :)
Thanks Brendan.
Correct, ground is ground! It worked because modern test equipment is often not connected to ground (safety earth) but isolated.
Another winner!
👍
Yvery nice Demonstration of this Special receiver and thanks for the gut alignment of all the Waves..! It is like a new ohne now.thanks a lot .
my pleasure
Some useful information, and some not so useful. The yellow brick road approach. Micro analytics. Knobs and switches, impressive. Nice! The radios antenna should be used for demonstration
It's becoming very easy to recognise an American design without seeing the name. They build everything very solidly. It's good for another 50 years minimum. Great job on the power supply and the mechanical issues.
Thanks.
Just catching up with this series Manuel. Interesting radio and well done as usual 👍
Thanks Dave
Esta serie de radios Zenith são iconicos, são radios classicos para os colecionadores, eu tenho o modelo 1000 e o 3000 ainda com seus componentes ainda totalmente originais.
Admiro muito seus trabalhos que são sempre de muito alto nivel.
Muito obrigado por compartilhar seus conhecimento em 2020, e espero que continue com seus videos em 2021 com muita saude.
Um forte abraço a todos da ilha da madeira.

Muito obrigado. Esperamos que 2021 seja melhor para todos, e com muitos vídeos à mistura 😊
Well done.
Thanks Lynton.
Great job again.
Thank you
5 star restoration as always!
Thanks
Brilliant work:
I have a preference to switch the AC input power supplies, and newer electronics there’s a tendency to have a cube (transformer) supplied on all the time and one switches the DC off at the device. This of course means that there is always some residual current pull from the mains, plus there is always a chance of fire with counterfeit power supplies. I usually plug my devices into a fused switchable computer strip. (Your home brew power supply is probably safer than commercially made devices)
It’s not ideal, but that’s what the owner had ...
I envy your guess star Normende FET VOM. Such a charismatic assistant. Makes me want one too. Please include it in as many of your future audio repair project. I want to see its full potential(where its needed of course). Great work sir as always. Thumbs up from Malaya!
I did a video on the nordmende em3366 repair. search for it on my channel.
@@electronicsoldandnew I have watched it few times. Hehe
Thanks for this vedio.i buy like this radio problem alignment please I want schematic diagram

Great job. Thank you for sharing. Anyway, when aligning the FM on the Zenith 3000-1 I have not seen the last 2 steps. I mean L103 - L101- L102 . On the instructions there are not figured, and I do not know where these coils are. Could you complete my information about that. I yet cannot make a perfect match between the scale and the 98 Mhz injected at the antenna terminale. Thank you for help.
I’m afraid I did this one some time ago and don’t have it with me anymore.
Thanks why you connect positif to the ground
The radio is a positive ground circuit.
انا اطلب من كل من شاهد اسمي ان يساعدني كيف احصل على هادا الراديو ولكم مني الف الف شكر لانني لا اعرف الاتصال بهم وانا محب جدا لراديو سني 64 سنة من المغرب
You dont seem too surprised. I assume its a good radio with not much maintenance required. Better than usual built in antena perhaps? I'm sure the owner will enjoy it.
It’s a great radio, but they can always surprise us 😊
I was awaiting this FM aligning video as it was something I didn't do with my TO 3000-1. Unfortunately my sig. gen. doesn´t do FM modulation but still the FM in my radio works very well.
One last word of advice: do not grab this radio from the handle; this is very heavy piece of gear and the plastic in the antenna/handle is notorious for ageing badly and becoming very brittle. Otherwise you can end up with the handle in your hand and the radio smashed on the floor.
Thanks for that piece of advice. I’ve warned the owner as well.
I heard you can put epoxy in the handle to make it stronger.

👍
The way you pronounce "There" reminds me of my wife, that was actually Portuguese, born in Oporto, but spent most of her youth in South Africa, in Kwa-Zulu Natal province... :)
That’s exactly where I did most of my growing up - in Pietermaritzburg, Natal.
Interesting video series, I appreciate it. Nevertheless German (over) engeneering seems to be quite successful in this world ;-)
And I love the days both Tony and you put out new videos. Thank you!
I’ve nothing against German “over-engineering”. In fact, the German radios of the 50s and 60s are great examples of the way that that philosophy advanced the world of radio.
As for your second paragraph: Me too. I get to relax because my editing is done for a while, AND I get to watch one of Tony’s videos 😊
I have two missing hinges on my top section of the front cover. I've tried something similar to what you did, but I can't get the new sheet metal to stick. Chrome does not solder well of course. How did you get yours to stay put? Also, which trimmers are for which SW bands? You showed how to align the LW band but I have no idea which trimmers are for which bands. Thanks!
It’s been a while so I don’t remember much about the trimmers. You must see the service manual. I believe I glued the hinges with epoxy.
ممكن ان احصل عليه والمصاريف على حسابي وشكرا لكم
Nice radio and a bit unusual design I must agree.
Wonder if anybody ever used those timezone maps and conversion system...
Cleaned up pretty well, nice job.
Hope your next radio (or whatever...) is a bit more of a challenge,
dead or no reception or noisy or something :-)
I also prefer it when they’re dead at the start. Must be a sucker for punishment 😊
@@electronicsoldandnew Great, so maybe it's hope for a part 3 of the Beocenter 5000 restorelog?
I have the same radio in your video, but I don't know the history . I have no power cord and still have to try batteries to see if it works. Do you know where i can find a power cord , and if it doesnt work, do, you do repairs?
Afraid not. Check out eBay.
Great restoration. You forgot to say 'and all that jazz' at the end thoug ;) ;)
Yes, messed up my lines 😊
You would have received more, and better, had you extended the antenna. The whip is for FM and shortwave.
A lovely unit, but I don't get it why the mains power supply was not included in the original design. It's much better than carrying another brick around.
True. I believe the next model up had one installed.
The transoceanic line of radios were specifically about being very good battery powered and portable receivers. What is missing on this one is the D cell battery holder, which fills the entire space between the chassis and the back cover.
👍
It is a great radio. You were picking up many more shortwave stations than in the UK, perhaps I need a better antenna? Interested to know what is in that PULL OUT section?
It’s a chart of shortwave stations and transmit times, and blank pages for you to keep notes on stations you picked up and when.
@@electronicsoldandnew Thanks, I wondered if it was that.
What did you use to clean the ‘stickyness’ off of the black leatherette? I have this radio but there is something sticky on some surfaces. What did you use to get the black shiny again?
Try cleaning with alcohol, then use Armor All. That may fix the problem. The feel is caused by the breakdown of the plasticizers used in the vinyl. The Armor All, which should be re-done periodically protects the plastic from the oxygen in the air, which, I think, is what, when combined with age, causes the plastic to deconstruct.
Couldn’t have answered better myself.
Curiosity, could you elaborate on your minny wip antenna, Is it a commercial product?
There is one available commercially but I built this one. The video on the reject is here:

Hats Off for your restoration work. I have the radio., but the front panel is missing. I will send you the picture. Can I get your email address? It was working-- I have taken it down from the self. Hope it will work, otherwise, I will follow your procedure to bring life to it. Datta Deogaonkar. Amateur radio operator. VU2 DSI, Ahmednagar India.
Glad you enjoyed your Zenith experience ! See the last Zenith T-O here. Some PCB's added & they
were plug in modules.
