A tápbol a vezérlő IC ami egyben a fet is intézi a táp hajtását.
Üdv mindenkinek.

Előre is köszi.

Dear Friends,
I am having a problem with the above mentioned amp. When I increase the volume from 0 to a quarter level the sound is OK. If I increase the level above quarter onwards , the sound becomes fuzzy and distorted. I have tried replacing the 2 filter capacitors(8200uf 50v) with 2 (15000uf 50v) caps but it is the same. Can someone give me a clue what can be causing this problem.
Thanks
Carlos Rajoo
