Sony Cdp-590
Sziasztok Van egy Sony cd játszó aminek sajnos nem lelni a rajzát sehol és a 591-es abszolut más belvilágú. Sajnos nem forgatja a lemezt a motor meg jó. a lézer próbálkozik. a motort egy LA6520 ic hajtja. Tud valaki ajánlani egy másik típust amiben szintén ez az ic dolgozik, hogy megnézhessem a vezérlés módját. Az ic adatlapja már megvan. Köszönöm Laci
Sony TA-F410 vs. TA-F411 erősítők között mi a különbség?
Sziasztok,csak annyit szeretnék tudni hogy a Sony TA-F410 és 411 típusú erősítők között mi a különbség,mert ugyan nem böngésztem át a teljes kapcsolási rajzot,de semmilyen eltérést nem találtam a kettő között,a 410-1989 es a 411 pedig 1990 es gyártású,az előlapon a felirat elhehezkedése tér el még,de ennyi,de az is lehet,hogy csak ennyi a különbség.
Köszönöm.
repair sony amplifier str-de254
Want to share: Have downloaded the schematics from this forum to help repair the amplifier of a friend. Turned out that Sony decided to route the earth through the chassis, even the earth between the various supplies. When one takes the main board out of the chassis and switches the amp on, there are up to 20 volts difference between the eart (and hence reference) of the pre-amps and the main amps. Luckily the amp goes into protection but from a design point of view it is not nice to rely on screws and aluminum face plates to conduct up to 0.2 amps of current from one supply to another. What I did is solder wires to every eart point and connected them on the main board to make it stand alone and not rely on conducting current through the chassis anymore. Bad design, simple repair but took some digging in the schematics to find out what exactly was going on!
