Sziasztok!
Adott egy kínai végfok, amiben a ventillátorok audio zajt keltenek a kimeneten teljesen letekert hangerőnél is. Ha lehúzom őket a tápról, akkor a zaj megszűnik. Mit lehetne ezzel kezdeni? Hurkoljam át párszor a vezetékeiket egy ferritgyűrűn, vagy mi lenne erre a jó megoldás?

Hi
I'm looking for a schematic diagram for this equipment:
Professional Power Amplifier XA-1000
The main fuse was blown and according the owner it blowns again after replacement.
He used a 40 amp fuse. The original fuse is not around anymore and there is nothing written outside on the label. So it's somewhat a lottery about the correct fuse rating.
Anyway, I would like to repair this equipment but without a diagram it would be a pain and nearly impossible.
Tryed to find a diagramwith Google search - negative. Also the manufacurer ist unknown this days.
Maybe a reader has more information aboutb this.
Thanks a lot

Sziasztok!
Hozzám került egy Marantz 5220 deck készülék javításra, amin semmi sem működik az audio részen. Hiába írnám le, hogy pl. már a fejhallgató kimenet sem egyforma, ez csak egy része a hibáknak. Tehát, mivel úgy tudom, a rajza nem nyilvános, ha tudna valaki segíteni magánban, azt megköszönném.
Üdvözlettel: Attila
Sziasztok
A címben szereplő aktív hangláda került javításra hozzám.
A PROTECT CIRCUIT hiányos, vagyis hiányzik az IC lábkiosztás alapján uPC1237 -re gondolok. Hiányzik a kimeneti relé X meghúzófeszültségű, ami méréssel kideríthető. A gond az, hogy egyéb ellenállások kondenzátorok IS ki lettek termelve a szakszerűtlen javítás alkalmával.(nincs bekapcsolási koppanás védelem, meg DC védelem sem!! a hangszóróra menő hangkimeneten.
A végfok Power tranzisztorok: 2SC 3519, és 2SA1386A 2-2db komplementer párok.
Sajnos az egész elektronika "szendvicsszerűen" lett összeállítva forrtüskék tartanak/villanyt vezetnek.
Bármilyen építő ötelelet szívesen fogadok. Az IC adatlapjából tudnék elindulni, de hátha valaki javított ilyet.
Köszi
Üdv
Szabi
