So I thought the only problem of my Rega RP3 was a dirty needle. I cleaned the needle using the Magic Eraser and found that sound is only coming out of the left speaker. There is a barely discernible sound coming from the right speaker.
I tried to narrow down the culprit as follows:
1. Not a speaker problem because I played a CD and my Xiaomi Mi Box and sound came out the right speaker.
2. I interchanged the RCA cables and voila - the problem is now the left speaker and the right one sounds okay.
Is the needle still dirty? Or is this a cartridge thing? Can this problem arise out of non-use? Hahaha. I have barely played my turntable because the needle got dirty, and just when I thought I had a solution, this other problem came up. And when I say barely, I mean it may be a year since I last played a record.
