Hi,
I am looking for a schematic of Nova DXP1400 SMPS Power Amplifier.
I have one to repair it.
The issue is, that of power off, the loudspeaker output siwtch a flowting voltange to it about 3-5 sec. which is switch between positive and negativ amplitude.
Any sources for it. Nova stops producing/repairing it, so no support at all.
Thank you
Sascha

Üdvözlet Mindenkinek!
A jelzett készüléket szeretném bevizsgálni,de a tulajtól kapott kódra nem reagál.Kérem, aki tud, segítsen. A készülék gyári száma:VWZ4Z4B0003124
Szevasztok!
A fenti erősitő előzménye, hogy a kimenetét 4db hangfallal jól leterhelték.
Ezt követően a hangerő poti kb. 1/5 álásánál elkezd torzitani és erőtlenné vállik minha nem kapna tápot.
A tápfeszültségek mindenhol rendben vannak. A torzitás kezdetekor a végfok IC lábán 2volt feszültségesés volt mérhető.
A végfok elótti nagyjelü meghajtónál is ez a torz hang van jelen.
Ha volt már ilyennel dolgotok vagy tapasztalat ötlet, kérném osszátok meg velem.
Köszönettel: Kitimi51
