Jolida 502B


Need some advice please.
Left channel has "busss" noise even the volume knob is at zero position. Input selector get noise when it is switched from time to time. Anyone has the same problem ?? I suspect dirty knob contact ?? Solution ???
Thanks

I have a Jolida Sj 502a and it has the same ploblem. I change the out put tubes without success. I thing is bad quality of some parts of amp.
