Hello, teachers, One of my SABA MT201, the FM frequency drifts, and the radio changes after it is turned on. Ask the teacher where I can check?

Hello, Thank you very much for the teacher's explanation. I turned on the machine and first checked the tuning cable part, and found that the screws on the cable reel were loose, causing manual tuning to fail. Second, I followed your steps again, checked the tuning circuit and replaced a triode. The state of the machine is normal now, thank you very much, teacher. I love this saba forum.

Hello, saba 9140, ask for advice on a usage problem: The 8 buttons in the lower right corner, FM-1-2-3-4-5-6-7, 1-7 are storage stations, The text below the FM button is, sus afc ein, what does this mean? I do not understand, At present, I cannot manually tune after pressing the fm button. Is there something wrong with me? On my 9140, the 7 storage buttons are normal. Press the fm button, manual tuning does not work, and the pointer can move. O1CN01iG5YKD2C5mlkty9JA_!!1518423.jpg

Hello, I'm waiting, but I haven't seen the picture. Where can I find it?

your good friend, I need saba 9241 series relay. Thank you very much for your help and guidance, it is best to have real pictures and specific operation circuit diagrams, I just find and learn. Or you have a real thing, I will buy it, can it? Best wishes! For one receiver 9241 or 9260 you have to order in your home country: 2 relays, 12 V, 2 x form c contacts, 8 Ampere 2 inductors 2.2µH, 5 mm pinning 2 resistors 2.2 ohms, 1 watt 2 diodes 1N4001 or similar Best regards, Christian[/quote]

Hello , Can I buy relays for 9141 and 9240 series in Germany? I need it, thank you teachers. 'O1CN01DDPKvK2C5mhzmsFUu_!!1518423.jpg'>

Hello teachers, Let’s ask a question today. My saba CD360, under the guidance of the forum teachers some time ago, has replaced the triode, and it is currently playing and recording normally. In the process of using, I feel that the signal of the machine is not so big, and the output signal is too small, that is to say, you need to turn on the volume key to hear the loud sound. Compared with other decks, I feel that the signal is weak and the signal is small. I wonder if my phenomenon is correct…

Thank you very much Reinhard, wolfgang.h，friend, I like saba products. I have no maintenance experience. Since coming to this forum, I have gained a lot. With your help, every fault can be solved. The key is that I have learned a lot of knowledge. Thank you, thank you friends. I will come to consult next time, thank you.

Hello, teachers, let me report on the maintenance situation in the past few days: 1. For several days in a row, I insisted on looking for the fault according to the instructions of the teacher, and I never found the cause of the fault, and the fault still exists. At the same time, I turned on another 9141, compared the search, replaced it with the replacement method, but couldn't find the fault. I was desperate, and I had the idea of giving up.

Your analysis is completely correct, keep the power cord plugged in, and keep measuring K1, 12V without powering on, and keep changing and shrinking the value. 'O1CN01qTxRa02C5mhmWihcQ_!!1518423.jpg'> 'O1CN01WDKD122C5mhe8Vmyj_!!1518423.jpg'> 'O1CN01wcnhNq2C5mhpM7DmR_!!1518423.jpg'>

I checked according to your instructions: 1. The filter capacitors C2218 (3300 µF) and C2217 (1000 µF) are in normal state and there is no problem; O1CN01VON39U2C5mhpSXnr5_!!1518423.jpg' data-cke-saved-src=' 2. Insert the power cord into the 220v power supply, and then press the power button to make the LED light up and go out after one second. After the LED is off, measure the DC voltage against the chassis ground on the measuring "K1". The result is that the voltage measured at K1 is approxima…
