start a process of elimination.
reverse TT's l/r rca cable into preamp. problem moves to right? that means it is definitely happening at the TT.
check/clean/redo/replace the jumper wires from cartridge to headshell/tonearm.
if removable headshell, remove, clean contacts on arm and headshell, tighten firmly (double check the azimuth at final tightening).
put l and r back to l and r.
still no sound except buzz one side? verify correct, then purposely switch the 4 left and right cartridge wires to send l to r, r to l. problem move to other side? if so, it's the cartridge itself.

problem doesn't move, problem somewhere else. Sometimes, we move a cable/connection when installing other equipment. unplug everything except the TT. still noise?
