A friend of mine bought the following car radio at a parts store, and it doesn't work. I found two so-called snowmen. The cause?
A friend of mine bought the following car radio at a parts store, which, contrary to the seller's claims, unfortunately doesn't play. Upon opening it, I noticed two capacitors (so-called snowmen) that are considered problem capacitors. They say 100/10 at the top, a production number below that I don't know, and 5/65 below that. That must be the year of production. The numbers at the top are probably 100uF and 10V. I need to know if replacing these two capacitors (one in the power supply and one in the radio) will make it play again. My friend paid €125.00 for it. The light is on, and there's a slight humming noise. Unfortunately, despite the antenna being connected, there's no FM reception. It's set to 12V. I hope for some helpful answers. Thanks! 🙂

Press the switch buttons for the bands K/M/L/U (before) All U for FM reception), because due to moisture (long non-use) corrosion forms at the mechanical band switches.
A power supply is available on this radio not, because it is already supplied with DC voltage. A greasy ELKO can only be installed for the audio output stage.
The brooding (50Hz) what you hear is perhaps your own power supply, because it does not provide a clean “battery voltage”, power supplies often supply unsurpassed voltages. In other words, Brummen is disturbing the music enjoyment, but in the car there is no 50Hz Brummen.
No one can tell you what’s broken.
PS:
It might be that someone (Möchtegern-Elektroniker) has “determined” the entire radio reception part, that you will not get back without the manufacturer’s matching instructions.
Good luck!
There are still Glättelkos in there even if it is already supplied with 12vdc from the battery. And they’ll all be over by age. The selector switches and all other mechanical contacts.
No, you never have to smooth.
The ELKO are intended only for decoupling the NF signal.
In the field of HF levels + ZF levels, large ELKOS nix have lost!
The questioner hears nix or has no reception on UKW.
It speaks of power supply and my possibly the audio output stage (it is a second device), this output stage will be connected to the radio.
I guess the radio is ver-bastelt (so HF/ZF reception part is detuned), thus scrap.
Here are information about car radio, it consists of 2 devices

Hello Transistor3055!
I have the radio on Friday 12.05. get back to play. There were 2 old condensers (so-called snowmen) that I changed against new ones with the same values (100uF 10V-). I didn’t do it exactly because the owner didn’t want it. It was enough to play it again. Unfortunately, we have not yet been able to incorporate it, since the opening was unfortunately enlarged. Probably the owner of the car had installed a Westradio, which was much larger.
The DC voltage in the KFZ is not stable enough and has many disturbing factors. Therefore, the voltage is smoothed in the terminal. Always.
you will not receive more
Hello, Ginpanse!
These aren’t so great prospects. On eBay classifieds I found it as well. That’s what the seller says. That’s what he said on the part market. This is already an expensive scrap (for 125,00€), and very annoying. UKW’s on it. It is a star transit of RFT Bj.: ca.1965-68 or 1969.
I’m sorry. If that has not been prepared, it will not run well if at all. Such old devices should only be bought if you have the necessary know-how to put them back in motion, especially at the price, the risk is simply too high.
Please justify this assertion, because FM in the UKW sector is still being broadcast and heard today.
Why should the car radio nix receive more?
because the contacts of the selector switches will be so severely damaged that it is only a case for the ton. If this is now an antique tube radio worth a few thousand euros, you would make the effort and solder new contacts that you have to make yourself. It’s not worth it here. That’s why the noise is coming.
Hello, Ginpanse!
The GDR Autoradio Stern Transit is now playing again at UKW after on Friday 12.05. 2 old capacitors with 100uF and 10V (so-called snowmen) have exchanged for new ones with the same values. The old snowmen are just scrap.
I’m glad! Then you made a deal
Hello, Ginpanse!
Yes, I am also happy for my friend who bought this car radio. It would otherwise have been quite expensive E-Schrott.
What glass ball? I have years of experience in repairing old devices.
Do you have a better glass ball? I see in my glass ball nix.
Hello, Ginpanse!
On eBay classifieds and eBay this device is often offered, and in some cases even more expensive. They’re supposed to play, and they’ve been sold. On eBay classifieds I found an already sold where there is still a cable that is missing from ours. I think it should be the connection for the antenna. The connection from the power supply to the radio with a plug is connected, and also the one for the loudspeaker with a luster terminal (3 poles). There is also a red cable.
