This is for all Technics TT with removable headshells.
I've discovered a resonance in the tone arm contacts to the headshell. The springs which tension the contact pins, holding it to the headshell contacts cause a lower mid peak. Its tiny, but I can hear it with some vocal recordings along with tapping the headshell with the back of your finger nail. I used some dielectric grease behind the pins and it greatly reduced it.
