Üdv!
Egy újabb beteg került hozzám.
Pioneer A-110 erősítő ami látszólag teljesen jól működik de ahogy elkezdem rátekerni a hangerőt kb. 1/3-nál elkezdi kapcsolgatni a kimenetet. Relé kattog, hang akadozik.
Ha lehalkítom akkor újra minden jónak tűnik.
A kapcsolási rajzot mellékeltem.
Előre is köszönöm a segítséget

Üdv Mindenki!
Van egy (ráadásul) saját végfokom.
Bekapcsoláskor kiül pozitív dupla tápfeszre (mivel H osztályú) utána beáll 0V a kimenet, de ez idő alatt a védelem megfogja és megáll. Az összes FET (IRF) illetve tranzisztor (MJ) jó benne.
Ha kiveszem a kapcsoló FET-eket akkor is megcsinálja ugyan ezt (!).
Ha a védelmet leakasztom indításra, majd vissza akkor utána tökéletesen "muzsikál".
Valakinek valami tipp?
A rajz itt is fent van.
üdv.
