Mit diesem Radio Saba Freiburg 11 wurden alle defekten Kondensatoren ersetzt , der Motor läuft gut in beide Richtungen, der UKW-Empfang ist in Ordnung, aber der Motor stoppt nicht bei starken Sendern, ratio-elco= 16v, neuer eabc80 und Ecl80: Wer kann mir weiterhelfen? Ich habe schon dutzende Stunden in diesem Forum gesucht, aber finde nicht wie ich weiter arbeiten soll ? Grüsse Koen Louage Bearbeiten

Hello Stefan, Sagnix and Peter, finally I got the boldness to try to re-align the UKW-tuner, just with the EM34 as indicator. It was hard, took many hours, and I lost my courage many times. But I reached what I wanted : without the automatic, I can receive 23 stations, magic eye 100% closing, even closing further ( if that is possible ) . Then I tried the same with the automatic, and the automatic stops on all the 23 stations. What a relief! The ratio-voltage varies between -11,2Vdc ( only on th…

Zitat von sagnix: „ Hello Koen, before you take further steps , you make the ratio voltage at 80 % deflection of the magic eye measure . If this is > 15V , is the shutdown of automatic beyond their tolerance. The switch-off is determined by the demodulated negatively directed IF voltage and a positive- adjustable back tension . For this the following SB -neck : Here all marked resistances should be checked . For forcibly increasing the switch-off level, a resistor may e.g. 220k are inserted befo…

Hello Stefan, I did the measurement with a 1.8Kohm and the other with a 12Kohm resistant parallel , I don't have other resistants coming closer to your advice . So V1 gives minus 1,06Vdc and V2 minus 1,3Vdc. Still different from the schematics, gives this to you a bether sight of what can be done ? Kindly regards, Koen

Hello Stefan, all the resitors are ok, they have been controlled many times. The voltage V1 measures minus 8,5Vdc and V2 gives minus 1,7Vdc, so higher than the schematic mentiones. So I hope you could give me additive advice ? Kindly regards. Koen

Hallo, after turning P5 at the left, I receive 14 stations ( EM34 100% closing) on which the automatic falls down, and some 9 stations who give only 80% closing of the EM34: these 9 stations don't be able to stop the motor. If I turn P5 slightly to the right, the motor doesn't stop at any station, even those with 100% closing of the magic eye. I have the impression that the UKW-tuner has to be re-aligned, but can I do this with only a multimeter?? Thanks for your help. Koen

Hallo, the radio works good on UKW, the automatic also, only he stops only on some 12 stations. When dialing without automatic, I find about some 10 stations extra, on which the automatic doesn't stop. I think it is a question of alignment, but I only have a digital multimeter. Is it possible to align with only a multimeter and of course the magnificent working magic eye EM34. Thanks for your concern. Koen Louage

Hallo, I hope someone can help me to get the automatic in good working condition : my freiburg 3ds works fine ( all bad capacitors have been replaced), I receive some 30 station ( manually, with automatic nly some 20stations) I'am a amateur with no technical education, I only posess a digittal multimeter. The ECL80 and EABC habe been replaced with NOS ex. ) My excuses for not writing in German, my knowledge is not so good. Thanks for helping me. Koen Louage
