Sziasztok . Van egy asztali erősítőm egy ideje azt csinálja, hogy terhelés nélkül vagy terheléssel, ha elkezdem emelni a hangerőt proterktbe megy. Kimeneti jelalak rendben van terhelésnél sem csúnya a jelalak.
Kérdésem az ,hogy a protekt jelző tranzisztor lenne a problémás ?
Elnéztem , végül szakadt volt a kicsatoló ellenállás. (2x0.22Ohm)
Sziasztok! Onkyo TX-7520 manuáljára lenne szükségem ha valakinek megvan köszönöm.
A két masina teljesen egyforma képek alapján.
A problémám a következő. kb 1 éve el csendesedett és az istenért sem találom a hiányzó alkatrészeket.
Sőt kapcsolási rajzot sem.
Az erősítő panel AR5500 felirat díszeleg. A bemeneti panelon pedig AR55xx v1.0.
két alkatrészre lennék kíváncsi ami nincs meg. U1 és az U2.
Ha valakinek van ilyen masinája vagy rajza. Meg köszönném.
A lényeg, hogy a két alkatrész számára lennék kíváncsi.
Sziasztok!
Tudnátok segíteni ebben? Valahol megvolt, de nem találom.
Köszi
