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!
sony erősitő végfok ic pótlás
Üdv Egy régi készüléknek a végfokja adta meg magát. Sajnos a beszerezhetetlen Si1125HD ic van benne. Ennek helyettese az STK4133II szintén nem beszerezhető. Van e a fiókjában valakinek elfekvőben valamelyik vagy tudtok valami más megoldást? A készüléket átépiteni nem szeretném mert a végfok az alaplapon ül és meg kéne tartani az eredeti állapotot. A készülék Sony STR-313L Laci
