Nordmende Export Super 8030 Radio.

[John10b]

I have been asked to look at the above Radio, I cannot find the circuit diagram for it, can any one provide me with circuit or a link. Many thanks.

I should have attached pictures. John

That looks like a late '50s or VERY early '60s mono set, and with three speakers, a decent one.
Usually the chassis number is more use than a model. I don't know of any with number identification, but what info I have starts at 1960. You MAY find a label with a chassis number which would help.
If you list all the valve types, I MAY have a circuit which could help.
That row of tags on the back usually has an ID for each function, so for instance to look at the S curve, no need to remove chassis, tip up at some silly angle to find where to connect your scope, there it is.
With later Grundig TVs, they had a diagnostic plug on the chassis. If you had the diagnostic tool (I had one), just plug in, switch on, and you get the fault area instantly displayed. The NordMende TVs of similar era had a similar arrangement (FC25 = Full Check 25) I think there were 25 test points. I did not have their diagnostic, but like the Grundig, you could measure at the test points.
These old NordMende radios proceeded all that by perhaps 20 years.

No schematic but here's the radiomuseum entry:

Thank you Lawrence and Les. The valve line up is shown in attached picture.

So, surprisingly for a big German set of this era, no VHF. I presume the owner is aware of the consequences of this, i.e. not much to listen to these days, unless you add Bluetooth or whatever.

[John10b]

Yes Nick I was rather surprised not to see FM, the owner is aware of this, I have not discussed ways around it, but either what you suggested or possibly a small TX, it will be his decision.
Les I cannot see any labels or markings on the Chassis, the only indication of model number is on the front.

There was a Nordmende Isabella E with partly the same valves.
A export set also with 5x SW and MW.

Thank you Roffe I downloaded the circuit, it may be helpful.

[John10b]

Sorry I got the wrong model number, it should be Export Super 8030.
John

[John10b]

Set now working, and what a performer, Rich tone and plenty of volume, I’m very impressed. The front end had a problem, the set had been got at and connections around the aerial had been damaged. If you look at the picture you will see one obvious reason set didn’t work correctly. Still some work to do mainly trying to clean contacts on numerous switches etc, getting a good signal from the Isle of Man.

MotorbikeLes #3, did you find the manual? I still have a few queries that I’d like to sort out. Thanks.

Thread title updated.

John, when I saw the "41" in your listed valve types, I knew I did not have it.
I photocopied the dealer schedule for 1960-61, printed in July 1961. It has a range of transistorised portables, then a range of three mono valve types, plus three more "stereo" valve models. (Stereo audio, not decoders then, but they could be retrofitted from 1963. I had a Tanhauser with the 3/632 chassis which I retrofitted with a stereo decoder in the late '80s.
Furthermore, ALL the valve sets have FM, whilst half the transistor sets are AM only.
Of the lower end valved sets, one has a single L/S, the second has two, but the third, the 1/618 Carmen has three. The valve lineup of that set is as follows:-
ECC85 (VHF front end), followed by ECH81, EF89, EABC80, EL84 plus the EM84 magic eye.
If you think that would help you, I could scan it possibly tomorrow.
Just to whet a few appetites, whilst some of the IF bandfilters could cost up to 10Dm, their EL84s were only 0.50Dm.

Thank you Graham for correcting title and thank you Les for your comments.
My only remaining query is about the missing ferrite aerial, a piece of wire has been put in its place, it’s not a show stopper but I always try to keep to original build. Also I don’t know what the contact does when the aerial is rotated. I have attached a few pictures.

Hi John I suspect the contact is for switching from internal ferrite rod to external to the socket on the rear of the chassis ,what a pity someone removed the coils ,I guess it would be possible to try a ferrite rod with coils from a scrap valve set ,you would need a schematic diagram . Mick.

[John10b]

Hi Mick, thank you for your suggestion I think your probably correct, I’m going to investigate further. I did search on utube and came across a video of a similar set and it showed the ferrite rod in position, and it appeared to be motorised. I’m thinking possibly when you select one of the piano keys it rotates etc.
Cannot see any motor on the one I’m working on, and I don’t have any circuit. Further investigation to follow.
I should have added that the ferrite rod can be manually turned from knob on front panel, unfortunately the string has broken.
John

[vinrads]

Hi John I have a Grundig and a Telefunken with the same arrangement , I need to dig them out and check out the coil on the ferrite rod ,it looks like there are three wires to connect . Mick.

[John10b]

Thank you Mick. From what I can gather there were numerous versions of this “set” and I think the one I have is the non motorised version.
I have attached a few pictures which shows the chassis of one with no pulleys, for motorised operation, and the other one I have , with pulleys, for manual operation.

Further to my last post I sorted out some bad soldering and the set works really well, even the magic eye is well illuminated on some stations, however it’s a great pity that it’s been got at which also resulted in the tuning glass being cracked.
