    Hello. Some history: 1. Change capacitor in supply circuit. 2. Working great for some months. 3. 3 weeks ago begining some problems: when I switch on, no voice in speakers. All buttons working, scale, led, all visually working, but without voice. During switch off - I listen some crash in speakers (the same, like normally switch off) When I several switch on/switch off - starting, and working great. 4. Every morning, I switch on/off several times, but from 3 times to begin, for many...many in th…

    Dear Reinhard, Impossible is my second name name. Do You prefer any producer, or I can use anyone? Needed 40V, can I use 50CV or 63V? allegro.pl/kondensator-10000uf…-sinecon-i6679826098.html or orginal: elektrodump.nl/en/elco-low-vol…voltage-10000uf-40v-.html

    Hi Reinhard, I chec kD2216, C2216 and 2,2 resistor. No deffects. But I check 10 000uf caps, and one was broken (no charging, and resistance was zero). I find the same from my "old chasis", change, and SABA now it's working. I woud like to change both caps to be sure, but could You tell me, can I change for anyone, for example: allegro.pl/kondensator-10000uf…sonic-hc-i6672272802.html or I need to find another?

    Dear Reinhard, Thanks. After disconnect St26 - fse burn again. I check D2247 (no 2211) - exist D2248 - working good. I have no tool to check 10 000uf, but observed, during checking resistance by multimeter: - one cap is in first is charging (from multimeter), and resistance is rising. After that voltage in cap is some mV - second cap have zero resistance, and no any mV in output after miltimeter resistance test I think second is defective, but I need to change both to be sure a capacity and to b…

    Dear all, My 9241 worked normally for a few days. In one day - I connect deck. Worked normally a few hours, normally switch to FM, and for deck without any problems. Some day during deck working, I increase volume (to 3...4 led) - saba shut down. Normally can on/off in main switch (stand-by led is working), but fuse 1,25A Si652 is burning always when want switch on receiver. Relay RS653 is working (I hear). Transformer 651 - I hear-is working. PS: maybe this problem is described in this forum, b…

    Hi Reinhard, You have a moore understanding and patience, tahnk You. I swapped working Right amplifier module from 9240 to 9141 tc. Via new cables (existing are to short). Not remove modules (transistors screws from 9141 and 9240 not removed), only dissolved cables in main board, and connected. Of course compatible colours: green to green, blue to blue, etc. After swap not hear sound at both channel 9141. After come back before (9141 with orginals, 9240 with orginals), 9240 are working right, 91…

    Reinhard, I check it. I connect only right worked channel from 9240. Of course disconnected old, and connected the same cable colours. After that, I can hear any sounds in both channels. I come back with connections, and 9240 worked right (uffff ), but 9141 right channel working like before (with discharged sound), but left channel not working. I must check it in headphones, bu I'm affraid, left channel is broken. Volume is only max 3 leds level tested, not more, and some 30 seconds time.

    Ok Reinhard, of course, thanks. I was clear all connectors, switches, relais, pins etc. All solder points are checked, some are resoldered. This is first step for any jobs from me. Could You tell me: power amplifier modules swap: do You mean module with amplifier transistors (voltage supply I was checked early)? When Yes, I must desoldering cables, and remove screws od transistors? Or can I connec via additional cables between 9141 and 9240 (of course disconnect all cables before)? I see some di…

    All solder joints on the main Board was checked - there's my first step. Cleaning all connectors, switches, points, etc..., but red Contact 60, I need to buy blue...theres for mainetance, not only to clear...you are right. 9141 have no much switches, there's fully electronic... But, step by step will be doit as You say. Many thanks for Your help, Reinchard.

    Hi Richard, Best wishes in New Year! Many thanks for Your help. Unfortunatelly swap modules did not any effects. I tested all possibilities, but effect are the same. Sound from speakers/headphones is low, and is deformed. Radio working, station seraching, all buttons are working without problems.

    Richard, In 9141 no these numbers, but I will try! 88339479e874.jpg 03b32730728c.jpg

    Richard, These modules are not indentical. From 9141 7501107300 I see in above relais - diode (not inside 9240), and rerlais is AZ2531-10-106 (in 9240 is AZ1531-10-1) From 9141 7501109500 R-channel I see empty R1131 place, in 9240- filled by resistor. For left channel I forgot check... Rest elements are the same (in first look). I have a photos, and when I will be acces to my computer reader - I send this place photo for compare.

    Hi Richard, Speakers are working with other amplituner. In headphones is the same, I checked other speakers, without change. I have manual, could you confirm to swap: relais module 7501107300 und driver module 7501109500? Right numbers?

    Hi Reinhard, Thanks for Your answer, and sorry for my pause and my mistake. In Green cable I have 1.6mV. My mistake, sorry. Now I measured again, results: -0.9...-3.0mV. In L1 ca 0.3mV in L3 ca 1.4...2.5 mV, but sometimes are others. .. I think my multimetr have some falses in this voltage range. I can search radio stations,but Sound its deform and very low. When I turn volume to 6, I can hear normal level music. Indicator worked, stereo lighted. With cd Player its the same. Now I was buy 9240, …

    Hello odiefan I speake English. I have 9141 tc. Amplituner started, all functions ale ok, but have some problems with sound in speaker and headphones. Sound is deform. After visit in service-they diagnose -damaged supply controller part no 593 490 219. I cannot się this no in Service Manual and inside amplituner. In forum elektroda.pl the same opinion. Service said -have other manual, other numbers, and part price ca 280pln (ca 80 eur). I have some Electronic experience, and maybe can repair wit…

    Ich habe eine 9141 tC startet, aber die Lautsprecher den Klang verzerrt, und wahrscheinlich ein wenig leiser zu hören. Die Kopfhörer als auch. Radiosender gewinnen, alle Funktionen zu betreiben. Der Service war ich fehlerhafte Spannungssteuerschaltung gegebenen 593 490 219, aber in der BDA fand ihn nicht und im Inneren des Verstärkers als auch. Was kann die Ursache sein, und wie man es beheben? Natürlich habe ich Pläne und elektronische Funktionen. Verzeihen Sie mir die Worte, aber nicht Deutsch…
