Dieses "billige Plastikradio" wäre beinahe im Hausmüll gelandet.
Ich bekam es in einem Korb voll mit mehr oder weniger kaputten elektronischen Geräten.
This "cheap plastic radio" would nearly have gone to the garbage.
I got it in a basket filled with more or less broken electronic devices.

Es ist eine wahre Trouvaille.

Organisiert wurde die Entwicklung dieses Gerätes damals von Texas Instruments, die - neben Anderen - von Bell die Lizenz hatten, die ersten Germanium Transistoren zu produzieren und die zeigen wollten, was man damit machen kann.
The development of this device had been organised by Texas Instruments who - amongst others - held licence from Bell to produce the first Germanium Transistors and who wanted to show what could be done with these new devices.

Dieses Mittelwellenradio kam mit 4 (in Worten: VIER) Transistoren aus.
This medium wave radio needed 4 (in words: FOUR) Transistors.

Drei dieser revolutionären neuen Bauteile sind im folgenden Bild mit gelben Pfeilen markiert. Der vierte Transistor müsste an der Stelle sitzen, die mit einem roten Pfeil gekennzeichnet ist. Er müsste so aussehen wie die Anderen, allerdings mit einem grünen Deckel.
Er wurde offenbar durch einen neueren Transistor ersetzt. Hoffentlich sind die anderen drei noch heil - diese Germanium Transistoren konnte man leicht zerstören.
Three of these revolutionary devices are marked with yellow arrows in the next picture. The fourth Transistor should be in the place marked by the red arrow. He should look like the others except from a green coloured top.
It obviously was replaced with a newer Transistor. I hope that the other three are sound - these Germanium Transistors could be destroyed easily.

Auch sonst ist in diesem Exemplar nicht mehr alles, wie es sein sollte:
Generally in this specimen some things are not as they should be:

Die beiden blauen Kondensatoren gehören nicht hinein, und sie haben auch die falschen Werte.
The two blue capacitors don't belong to this era and they have wrong nominal values.

Der mit einem blauen Pfeil gekennzeichnete Lautsprecher ist ebenfalls nicht original.
Er passt zwar elektrisch, aber Form und Grösse stimmen nicht. Da dürfte Originalersatz schwierig zu beschaffen sein. Ich denke aber, dass ich einen mechanischen Adapter bauen kann, damit der vorhandene Lautsprecher zumindest sicher sitzt.
The speaker, marked with a blue arrow, is not original. Although he fits electrically, form and size don't fit.
In this case, original replacement might be difficult to get.
But, I think, at least I could build a mechanical adapter so that it fits snugly in place.

Ausserdem fehlte die Ferritantenne (grüner Pfeil). Einen Ferritstab passender Grösse hatte ich zufällig im Fundus. Nun muss darauf noch die Antennenwicklung für Mittelwelle angebracht werden. Das sollte aber auch machbar sein.
Also the ferrite antenna (green arrow) was missing. However I happended to have a ferrite core of almost the same size in my drawer. So now only the antenna coil has to be wound around it. That should be no problem.

Ausserdem hat jemand auf der Rückseite der Platine recht unprofessionell Änderungen vorgenommen, möglicherweise um die Schaltung an den neuen Transistor anzupassen. Ich muss daher die Schaltung einmal komplett überprüfen.
Besides, someone made rather unprofessional changes on the backside of the printed circiut board - maybe to adapt the circuit for the new Transistor. So I will have to check the whole circuit.
