Im not sure if its the right section but can anybody please help me regarding my issue i really dont wanna deal
with the 50hz tone playing when i want silence
Ok if i short buzzing signal to the ground it gets a little bit qmore quiet but than the silent channel starts to buzz if i short both channels together the silent shannel pops and remain silent. If i desolider the input wire both channels are quiet if i touch the input it react like normal and start to buzz 50hz as long as i touch either of the channel. It wasnt a case until i replaced the chip last one died when i touched back of the pcb.
If it started when the chip went bad, check all the solder joints, then the tantalum/electrolytic capacitors.
Thanks for the reply. How do i check the caps? I only have a value digital multimiter
with out capacitance check option. Further more at the time i bought those caps
i didnt know the leaguer caps are the worst quality brand
I reccon you know more than me in electronics im looking forward to learn more about analog electronics in general.
Can you tell me what c8 do is it some kind of filtering maybe this could be the issue? But if it is it should affect all channels so there is only film caps left witch could affect one of the channels right?
