I remember seeing Zenith radios in my Dad's Readers Digest in the 70's and always wanted one. It's only taken me about 50 years. I paid half the cost of the radio to have it shipped from the USA. The FM r.f. transistor needed replacing and the band switch needs attention, the bands don't line up, however I use it both day and night. Works well and a beautifully designed radio to look at.
There is a lot going on in that band switch - a good electronics contact cleaner like Caig Labs DeoxIT applied to the contacts and exercising the switch can work wonders. Exercise caution in application and do not get anything on the band / freq scale drum . If the bands aren't lining up it is in the switch - if the frequency is off on the scale and still in band it just needs a simple alignment. Thanks for watching !
My dad had one of those for years when I was growing up. We would go camping and we would sit up at night and listen in on the short wave and he would tell us where on the planet we were listening to.
I had a Lafayette HA800 that I got at a garage sale when I was a kid and I listened to all kinds of stuff. Numbers stations , Military stations, Ham, and broadcasts. Lots of fond memories and I regret selling that radio. Thanks for watching !
Fascinating! I have a Royal 3000-1 and a Royal 7000 (both Transoceanic radios of course) but I left any repairs (which were minor) to the local repair shop as I’d make a real mess of that. It’s amazing how each one of these was hand assembled in the USA. Very expensive radios at the time but they were indeed built to last.
You are welcome ! Sounds like you got a good score. This one came from the flea market at a tractor show. It pays to keep your eyes peeled for radio stuff in places you would not expect. Enjoy and thanks for watching !
Thank you ! It is in good shape. I was pleased that it had the power cord and manual. Whenever you pick up one of these it is always a crapshoot if it works or not. I'm glad It was a simple fix and I didn't have to dig through all of those ceramic capacitors :) Thanks for watching !
That was the R7000-2 which was the true end of the line. They weren't a resounding commercial success but definitely added some less laborious design practices and maintained good performance. In competition with the imported radios with the lower price point the writing was on the wall. Thanks for watching !
Thank you ! Every time I take on a project like this I learn something new. It definitely gives me an appreciation for the work that went into assembling a multiband - multimode radio before IC's and microprocessors. I can see why the radio commanded a $300 + dollar price tag in the early 70's. Its like a Curtis Mathes television. Thanks for watching !
@@survivalcomms You are 100% correct. It's funny to see the ease at which you can create communication with a spark gap system and then from that rudimentary set of components, you move forward to something like this... It is all a work of art.
I have one of those. Nice radio. Only problem is the BFO is flaky. R7000 was a continuous coverage of the 3-30 mhz HF spectrum. Earlier radios, including this one only covered small segments of the SW spectrum. WX radio and FM bands used a separate front end tuner than the LW-BCB-SW bands.
When I was growing up I saw these in the stores but couldn't afford it. Sadly shortwave radio is not like it use to be in the 50s and 60s. I bought a Hallicrafters S-38 used to listen to shortwave.
I couldnt afford it either. I had a Lafayette HA 800B that I got at a garage sale. Many fond memories. There is something about tuning across a log scale that makes it soulful. Thanks for watching !
Good morning , i Neeson your help, my Zenith trasoceanic 7000 only noise in AM, I do not listen to any station, perfect FM, I appreciate your comments, thank you very much
Fantastic Job! you inspire me to upgrade the electrolytic caps on my old D700D. I'm replacing most electrolytic with modern caps (solid polymer, wet tantalum, tantalum polymer. etc) The problem is that some are very small. Any advice you can give me I'll appreciate it. On the front I can see the 1000UF, 300UF, 500UF, but I can't figure out the small cap on the upper left behind the gain switch; do you know the value and voltage? I also ordered several in quantities so I can send you a kit as a thank you for your video. 73 Thanks
Of all the TO's I have, including R7000-2, this one is the hottest. Love it, but one has to be careful of the plastic. As it ages it gets more brittle. I have a broken top flip, that I wish I could get a replacement for. Broke close to pin. I superglued it, but how long will it last.
I am interested in the external tuner input with the RCA plug you removed? I cannot find any mention of it anywhere on the internet etc. I cannot find a copy of the operators guide that came with radio. I am wondering if that tuner is an antenna tuner? Any help would be appreciated . Great video .
I just bought a Royal 7000 at the local thrift store. It's in perfect condition - except - it has the same issue as the one in your video. FM but no AM bands. I don't have the repair manual but based on your video I think I'll try just replacing the same 3 transistors. I'm just wondering if you think that's a common issue with these radios? Any thoughts on the probability that mine has the same issue?
It's worth a shot. The transistors are cheap. Radio Museum has a cross reference from the zenith numbers to nte equivalents. I believe is is pretty common. Thanks for watching !
I have a D7000 bought from eBay. Both FM and AM receive only a few strong stations. The audio is distorted, and the tuning behaves as if the receiver has a very narrow bandwidth.
I have a Zenith 7000 royal, I wanted to learn to tune align calibrate just like you did. Make a video explaining how to calibrate this Zenith 7000Royal. Thanks sp / sp Br
i have the same model. AM/FM works short wave is not working. I was working fine then went south. Any idea where I can get it repaired? Would sure appreciate an answer.
Do a search for vintage radio repair. Toms Antique Radio repair in Dayton is one. It pays to shop around a bit but a good vintage repair shop is worth it . Some shops get lots of tire kickers - let them know you are serious about having it repaired and be open to the fact it might be more than it's worth in expense. Thanks for watching !
Hello, I purchased a Zenith Trans-Oceanic D700Y. The Am only works if you turn the gain control. . I get no SW stations. Should I? Could you have a video showing how to replace the dial bulbs please. Thanks for you help. Tom Woodruff
Check the antenna connections in the back of the set ensure that the waverod antenna is connected . It is the terminal second from the left. Do you have a signal generator ? Shoot me an email and I will send you what info I have to assist you. email is my channel name at gmail dot com. Thanks for watching !
Is there a hiss or any audio emanating from the radio when you are on any of the shortwave bands ? When you turn the band selector is there a pop in the audio ?
Hola amigo tengo uno igualito al video y no da fm ni am prende normal pero no da las emisoras fm suena y se va asi la señal esta chasqueando se va y viene el audio no se que esta pasando puedes ayudarme quue esta fallando
I have the same radio with the same problems. You want to fix it for me? I pay postage both ways and repair bill. If so let me know. My Dad who's gone now bought it for me back in the day, has sentimental value.
I'm not sure how you determined which transistors to replace. I would have thought you would have at least used a transistor checker on them. It's never a good idea to shotgun replace stuff because you could be inserting additional problems that will multiply the issues.
You replaced all the transistors in the AM section, seems unusual that all would be bad. Did they all test bad or did you just do it because you felt it was the prudent thing to do? Great video BTW.
Bought one of these in the PX while on exercise in Germany, in the American Sector with the British Army. Saw it in “The Italian Job” and had to have one. 148 dollars 50 years ago so not cheap. Loved the aerial in the handle but mine didn’t have this. Obviously a weak spot in an earlier model, but top quality construction otherwise.
That's awesome ! Radios like this have so much history to so many people. I have had so many people bring up thier memories of sets like this. Thanks for sharing your story and thanks for sharing !
Hi, I have the D7000-1 and the AM band works well, except between .65 to .90 MHz in BC (and in all the rest of the AM bands in that dial area). Do you know what could be the cause for this? I measured the test points with a voltimeter, but I don't know if the measures I got are normal. The voltage difference is about -0.1V in points 1 to 5 , +0.34V in point 6 and +0.4V in point 7. Thanks!
Can you help me with this one? My unit everything working perfectly. the only issue I have on this is the light on the dial and map light not working. Is that lightbulb out or something else. Thank you
Put a D cell battery in the back in the spot that fits one battery, or the switch that operates the lights needs to be worked back and forth a few times or cleaned. Mine worked after exercising the switch about 20 times.
@@HaiTran-eb3ce Yes. If there is still a problem, then the switches may need cleaning with an electrical contact cleaner that is sprayed INTO the switches. Be very careful to cover all other parts of the radio to NOT get contact cleaner on it, (or your eyes)! Contact cleaner is only used on electrical contacts and switches. The spray is pressurized and will go everywhere, so cover and protect all else. Use very short burst, then operate the switch back and forth, then see if it works. Sometimes it takes several times to work. This also works on volume, tone, channel, and Other types of electrical connections. The same Cautions apply. Bulbs may be burned out or need to be unscrewed and screwed back in, or just tightened.. Bulb #123, 1.5 volt. Screw in/ out. found almost everywhere that has flashlight bulbs Good luck !
I have a D7000Y like you do, and I replaced all three AM/SW transistors as those bands were dead on my unit. They work well, but now I've a new issue. The radio is well overdue for a recap, and if I crank the output wide open, I can hear faint audio when I press my ear against the wide-range driver. It used to wake up and play normally at times, but this is no longer the case so it's just faint. I've never recapped a radio before, though I watch a lot of Shango066 so I have some idea of how to recap one. The question is, where and what (Electrolytic?) capacitators should I change out? My unit has the 500MDR70 Chassis, same as yours. I also have a digital copy of the service manual.
Typically you recap the whole radio when you do a project like that. It sounds like your problem is in the audio amplifier section and it may be a bad connection. Before you go whole hog on a cap replacement do a wiggle test on some of the components and see if audio comes back. Thanks for watching !
@@survivalcomms Btw, I did a video earlier back when the radio would proceed to wake up (which it actually did while I was recording, and scared the bejesus out of me). So here you can get a better idea of the issue I'm having: photos.app.goo.gl/R9azn4cuiEQTGbsG7
I have the exact same radio, bought it new in 1978. It appears to have the same issue as yours, nothing output except FM. I used the RF gain nob and it quit. Where did you get the schematic?
I have two transoceanic 7000 radios. One is the 7000-Y and the other is a 7000-1. Both have weak AM. In each radio I replaced the three transistors in the AM section without any improvement. I'm thinking each of the radios needs to be aligned. Can alignment which has drifted off over time cause the weak AM reception?
Hola, compre un Zenith Royal 7000-1 y le he puesto pilas nuevas y suena como si las pilas estuvieran agotadas, no se entiende nada, el volumen a tres cuartos o más para que se oiga algo. Podria poner un vidio relacionado en este tema por favor. Como podria solucionarlo?. Gracias se agradece una alluda de un profesional. Pedro G.
Hola buenas noches desde Madrid España, el caso es que recibo en todas las bandas menos en VHF lo raro es que se olle como tartaja no es claro, fatal, mal. El volumen tres cuarto o más para digamos que aga ruido. que puede ser potenciometro de volumen?. Muchas gracias
@@JUSSI607 Podría ser la olla de volumen. Un pequeño limpiador de afinadores no haría daño. ¿El altavoz se ve bien? Si afecta a todas las bandas podría ser el amplificador de audio. ¿Cuál es su dirección de correo electrónico. Puedo enviarte algo de información.
Hola, emprincipio pense en un limpiador de contacto que biene muy bien, la radio no esta desmontada, pero me da que soplaria el altavoz y no es el caso creo.Tiene pinta de ser el amplificador de audio.

Man how are you doing ? I hope you are doing well. I got a question for you. I am in the same, and with 0 knowledge, plus the one I am acquiring with your video. The power supply with 3 pins is it for the battery power supply ? And the 120 volts, were do I take the wire, I mean, were doest it go solding ? I am lost, no manual, no diagram. Could you help me, please ?
With light squirts of a good quality tuner spray such as deoxit. Just on the contacts. manipulate the switch several times. sometimes it helps to repeat the process the following day. Thanks for watching !
SurvivalComms Thank you. ((If successful, eventually you will see my radio showcased on “Tom’s Radio Room Show “ UA-cam channel, As eventually all my radios have been/ will be. 📻🙂
SurvivalComms Well, I sprayed the DeoxIT as you said. I was VERY careful to cover up the plastic roll, but somehow some got on it, and made what looks like a cigarette burn.🙁. At least it’s not in a place or way that affects anything ( just looks bad). The BFO seems to be working better, but there wasn’t anything on in the short time I tried it. Still no VHF/ Weather Band. Sounds like putting a seashell to your ear- nothing more.. But I have other radios for Weather. Eventually it will have to be gone through, but it seems to be working sufficiently for the moment. (Can that barrel be replaced - and are they available ❓ 📻🙂
I wanna ask the same thing I just adquire one and is super dirty and the reception is sketchy and some of the frequencies are not working. Thanks for sharing the video!
@@survivalcomms Don't get me wrong...I think you did a great job, Especially when the radio was in such great condition. At least Zenith went to silicon instead of germanium, which increased reliability. I realize that you really did need to do a chassis removal because of needing to do an alignment, cleaning the band switch and controls. Overall good Job. I rebuild guitar amps and synths and will check around first to see for curiosity what went wrong. But then,if you want to do it right get rid of the Bumblebee's,wax caps and any other hi-failure components. Zenith did some very good builds in their Tv's and radios. That one you were working on is a keeper. I would have most probably have done exactly the same. If you ever do an older tube amp ,you probably already know this but just in case. Get rid of the death capacitor on the A.C. Line. If that cap shorts the chassis can go full line voltage hot. I've seen some nasty shocks delivered by this problem *Cheers* It's a shame I still prefer ECG transistors over NTE but..we can only work with what we can get now.
@@larryfried7742 Thank you ! I was fortunate to live close to an electronic surplus dealer when I lived in town and it was great for small items like those transistors. Having to mail order is a buy in bulk endeavour as you know. I haven't messed with any tube stuff in awhile. I have a few here but my solid state collection has filled the radio room and has prolapsed into the library..... Thank you for the tips and thank you for stopping by !
I just picked up one of these, can you tell me what is the receiver sensitivity you measured on the SW bands and the weather bands? The manual says 2-3 microvolts but its more like 10-15. What do you usually get them down to? Thanks
5 or less is pretty good. IIRC its 3-4uv in SW and 3uv for WX. Have you done a full alignment ? and is it all the different SW bands? It's easy to miss the peaks and valleys when aligning the radio. Thanks for watching !

My unit has the 500MDR70 Chassis, same as yours. I also have a digital copy of the service manual.
Typically you recap the whole radio when you do a project like that. It sounds like your problem is in the audio amplifier section and it may be a bad connection. Before you go whole hog on a cap replacement do a wiggle test on some of the components and see if audio comes back. Thanks for watching !
@@survivalcomms Will do!
@@survivalcomms Btw, I did a video earlier back when the radio would proceed to wake up (which it actually did while I was recording, and scared the bejesus out of me). So here you can get a better idea of the issue I'm having: photos.app.goo.gl/R9azn4cuiEQTGbsG7
I have the exact same radio, bought it new in 1978. It appears to have the same issue as yours, nothing output except FM. I used the RF gain nob and it quit. Where did you get the schematic?
Shoot me an email. My channel name at gmail.com
Me tocó i have the same problem and i need thr schemstic plz
I have two transoceanic 7000 radios. One is the 7000-Y and the other is a 7000-1. Both have weak AM. In each radio I replaced the three transistors in the AM section without any improvement. I'm thinking each of the radios needs to be aligned. Can alignment which has drifted off over time cause the weak AM reception?
Radios go out of alignment due to component value changes over time. There are a lot of variables. Thanks for watching !
Hola, compre un Zenith Royal 7000-1 y le he puesto pilas nuevas y suena como si las pilas estuvieran agotadas, no se entiende nada, el volumen a tres cuartos o más para que se oiga algo. Podria poner un vidio relacionado en este tema por favor. Como podria solucionarlo?. Gracias se agradece una alluda de un profesional. Pedro G.
¿Está en AM y FM? Usted está recibiendo estaciones y es sólo mal volumen ?
Hola buenas noches desde Madrid España, el caso es que recibo en todas las bandas menos en VHF lo raro es que se olle como tartaja no es claro, fatal, mal. El volumen tres cuarto o más para digamos que aga ruido. que puede ser potenciometro de volumen?. Muchas gracias
@@JUSSI607 Podría ser la olla de volumen. Un pequeño limpiador de afinadores no haría daño. ¿El altavoz se ve bien? Si afecta a todas las bandas podría ser el amplificador de audio. ¿Cuál es su dirección de correo electrónico. Puedo
enviarte algo de información.
Hola, emprincipio pense en un limpiador de contacto que biene muy bien, la radio no esta desmontada, pero me da que soplaria el altavoz y no es el caso creo.Tiene pinta de ser el amplificador de audio. Mi correo elminivatico@gmail.com el vidio que propocionastes es genial, le he visto 4 ó 5 veces me fascina el trabajo de los tecnicos profesionales en las Radios antiguas. Me imagino qué si no son iguales son muy parecidos el Zenith Transoceanic Royal D7000Y y é Zenith Transoceanic Royal 7000-1 Cordial Saludo
Man how are you doing ? I hope you are doing well. I got a question for you. I am in the same, and with 0 knowledge, plus the one I am acquiring with your video. The power supply with 3 pins is it for the battery power supply ? And the 120 volts, were do I take the wire, I mean, were doest it go solding ? I am lost, no manual, no diagram. Could you help me, please ?
QUESTION:
How did you clean the band Switch ❓
With light squirts of a good quality tuner spray such as deoxit. Just on the contacts. manipulate the switch several times. sometimes it helps to repeat the process the following day. Thanks for watching !
SurvivalComms
Thank you.
((If successful, eventually you will see my radio showcased on
“Tom’s Radio Room Show “ UA-cam channel,
As eventually all my radios have been/ will be.
📻🙂
@@jeffking291 I look forward to seeing that !
SurvivalComms
Yeah, so does TOM🤣❗️
SurvivalComms
Well, I sprayed the DeoxIT as you said.
I was VERY careful to cover up the plastic roll, but somehow some got on it, and made what looks like a cigarette burn.🙁. At least it’s not in a place or way that affects anything ( just looks bad).
The BFO seems to be working better, but there wasn’t anything on in the short time I tried it.
Still no VHF/ Weather Band. Sounds like putting a seashell to your ear- nothing more..
But I have other radios for Weather. Eventually it will have to be gone through, but it seems to be working sufficiently for the moment.
(Can that barrel be replaced - and are they available ❓
📻🙂
Muy bueno pero me gustaría en español
I have one in the boxs working
Very cool ! Thanks for watching !
Would like to learn how to do that.
Once you start and get a rhythm established your house will fill up quick :) Thanks for watching !
Would you be able to help me with my Zenith TO radio? Thanks, Rob
I wanna ask the same thing I just adquire one and is super dirty and the reception is sketchy and some of the frequencies are not working. Thanks for sharing the video!
Maybe..you should have checked the transistors first? They plug into sockets, yes? In these radios the transistors do go open.
It was cheap enough to replace all of them than try to piecemeal it. Thanks for watching !
@@survivalcomms Don't get me wrong...I think you did a great job, Especially when the radio was in such great condition. At least Zenith went to silicon instead of germanium, which increased reliability. I realize that you really did need to do a chassis removal because of needing to do an alignment, cleaning the band switch and controls. Overall good Job. I rebuild guitar amps and synths and will check around first to see for curiosity what went wrong. But then,if you want to do it right get rid of the Bumblebee's,wax caps and any other hi-failure components. Zenith did some very good builds in their Tv's and radios. That one you were working on is a keeper. I would have most probably have done exactly the same. If you ever do an older tube amp ,you probably already know this but just in case. Get rid of the death capacitor on the A.C. Line. If that cap shorts the chassis can go full line voltage hot. I've seen some nasty shocks delivered by this problem *Cheers* It's a shame I still prefer ECG transistors over NTE but..we can only work with what we can get now.
@@larryfried7742 Thank you ! I was fortunate to live close to an electronic surplus dealer when I lived in town and it was great for small items like those transistors. Having to mail order is a buy in bulk endeavour as you know. I haven't messed with any tube stuff in awhile. I have a few here but my solid state collection has filled the radio room and has prolapsed into the library..... Thank you for the tips and thank you for stopping by !
I just picked up one of these, can you tell me what is the receiver sensitivity you measured on the SW bands and the weather bands? The manual says 2-3 microvolts but its more like 10-15. What do you usually get them down to? Thanks
5 or less is pretty good. IIRC its 3-4uv in SW and 3uv for WX. Have you done a full alignment ? and is it all the different SW bands? It's easy to miss the peaks and valleys when aligning the radio. Thanks for watching !
