@reubensm I understand there will be pops and click sounds when listening to a vinyl record. The crackle sound that bugged me is something abnormal.
Last night I have adjusted the counter weight and tone arm as per musiklava79 suggestions. Now the crackle sound has gone nearly 80%. New problem is continuous pop sound are coming. I'm suspecting that this is causing by fine dust on the records. Looks like I badly need to brush the record before playing.
How do we prevent this fine dust entering into the room.
This is one biggest problem in my home, I clean my PC and audio gear daily two times to get rid of the dust.
