Sansui A-510 erősítő nem nagyon reagál a hangszínre.
Üdv!

Lenne ez a erősítő. A mélyre nem nagyon reagál, mindkét csatornán, a magasra úgy ahogy, igen.
Próbálom mozgatni a poti tengelyt, de semmi....
A balance, mély, magas potik egy fém hidra vannak erősítve, és úgy beforrasztva.
Mielőtt kibontom a hidat, lehet valami más bibi a hangszín körül?

Yamaha CDX-590 laser adjustments?
I have a Yamaha CDX-590 CD player and it skips on some CDs - original CDs, these CDs play without problems on my other CD players. I have changed the laser unit (KSS-210A) but this didn't solve the problem. When I turn the player upside down, it plays the problematic CDs without a problem. That's why I think the laser needs adjustment. I have only a service manual for the CDX-493/593 but they should be very similar to the CDX-590. It seems that the adjustments are done via "test mode" of the CDX-590, unfortunately there is not much information, how to exactly, in the service manual. Here is a picture of the PCB. http://www.volny.cz/hwtest/PCB.JPG Here are the "test mode" sections of the service manual. http://www.volny.cz/hwtest/TM1.GIF http://www.volny.cz/hwtest/TM2.GIF In "test mode" I have tried Auto adjustment mode 1, 2, 3, but I don't know if it should work fully automatic without any intervention or when the mode is fineshed and I can proceed to the next one. So I activated mode 1, waited a while, activated mode 2, waited a while, activated mode 3, then exited test mode. It didn't help. Mode 1 - only a short blink of two horizontal dashes on the display and thats it Mode 2 - started "play" without sound from a strange time 99:00 (the test CD is not so long), after a while it skips to another time, "plays" a while, then skips back and "plays" and so on, I left it about an hour and it was still going on Mode 3 - seems to be very short as mode 1 I think I'm missing something ... Maybe someone did this or even serviced Yamahas in an official service and can provide information how to adjust the laser? Or maybe the problem is not the laser?
Onkyo A-830 végfokhiba.
Sziasztok!
Abban kérném a segítségeteket, hogy egy Onkyo A830-as erősítőnek kellene a rajza. Pontosabban elég volna csak a végfokról. Föltettem az SM-keresőbe, de pont olyan nincs. A hasonlóak mind IC-s kivitelűek, ez pedig tranzisztoros, mégpedig jó sok tranz-al van felépítve Jó volna, ha valakinek volna a végforól rajza, mert a többi ákör, és a másik végfok működik.
Köszönettel:
Attila
Philips FW C380 mini hifi nincs jel a végfokok bemenetén, a fejhallgató működik.
Kérem sistvan ne szóljon a topichoz!


Hi! Tudnátok segíteni? Lenne ez a mini hifi
https://elektrotanya.com/philips_a01-155_fw-c380_service_info.pdf/download.html Van egy kapcsoló jack aljzatban (ami működik), ha bedugom a fejhallgatót lenémítja a végek bemeneteit. Ha nincs bedugva a füles a 3651 3652 megvan a jel, de a AMP_LEFT meg az AMP_ RIGHT már nincs. (12. oldal)
Az az igazság, hogy nem látom át, hogy ez a jack kapcsoló hogyan vezérli ezt a némító ÁK.-t Kösz
