I had this happen to me a while back and found that one of the conductors from the tonearm to the output terminal was failing, making that channel much quieter than the other. I installed a new wire and all was fine.
Turntable channel imbalance
Hi there!
I’ve noticed that the left channel is a bit louder than the right when I play vinyl. This is the only source that has this issue. I have 2 carts and both exhibit the issue. With some records it is more noticeable than others tho.
Is there anything I can adjust?
I have Technics SL-B20D P-mount. TIA
