Jó estét Kollégák! A fent említett nagy magnó rajza kellene, de sajna a neten csak fizetőset találtam. :-( A hibái: rossz a végfok ic mind a két oldalon, tda 1011a. Próbára lett beletéve próbanyákon tba 810, de akkor a magas, a mély ás a surround szabályzás nem megy, csak loudness van. Rádiója fm részén : nincs sistergés/zaj/, adókat alig fog. Az antenna helyzetére nagyon érzékeny, és az adókat is igen halkan fogja. Ha lenne valami ötlet? üdv:atis
Mérőszalag
Magnófej beállításához keresek 4 sávos mérőszalagot. Megfelelne egy bizisten jól beállított (stúdió)magnóval házilag készített szalag is. köszi előre is
Stage Line STA 502 erősítő egyik oldal hibás. Kapcsolási rajzot keresek
Üdv mindenkinek,
az erősítőnek az egyik oldala elszállt és valaki orvosolta
a problémát kicserélt mindent ami szerinte rossz volt
viszont elkövetett egy súlyos hibát  A 2SA 1694 és
a 2SC 4467 helyett BD 29-250 használt.
Esősorban rajzot keresnék a készülékhez.
Ennek hiányában is meg tudom javítani de szeretném
látni a kapcsolást,már kerestem a neten de eddig sikertelenül
talán valakinek meg van ennek az erősítőnek a rajza.
Előre is köszönöm a segítségeteket.
 
KRK VXT4 studio monitor speaker - mains hum. Schematics required
Hi - I have a pair of KRK VXT4 studio monitor speakers. Very expensive! When I stored them, they were working fine. When I tried to use a few days ago, one of them simply hums loudly at 50Hz. I have tried replacing the two 12000uF PSU capacitors, as I found on Google that sometimes they can become depolarised but this has not solved the problem. I am trying to find a schematic for both the main board (which has the PSU and the PA stage) and the pre-amp board. - Thanks, Kevin
