What cartridge are you using? That arm has a super light mass of 3 grams!

Rumble question- Thorens/black widow
Hello, I've been a reader for a while but this is my first post. Thanks in advance for any help/advice!
my turntable makes a very soft rumble sound mostly audible between the tracks or in very soft passages of music. I know the noise floor will never be like a cd but I would like to address this as I don't hear it in my previous turntable which is a cheapie.
I have a thorens td125mkii w an infinity black widow tonearm. I suspect the sound is actually due to the tonearm. That's because it seems to be microphonic, because if I gently rub my finger on any part of it, you can hear the gentle rubbing sound get picked up. This is the first black widow- it doesn't have damping trough.
-do you think the rumble is from lack of damping or maybe not?
-can I diy damp the arm easily to test it?
-or what else might be the problem? It has original wiring but theres no hum or feedback at all.
Thanks and sorry if this post was long!

That Ortofon is a good match with that arm,here are the results from vinyl engine,a perfect resonance of 11 hz. The problem is not with the arm and cartrige compatibility! https://www.vinylengine.com/cartridge_resonance_evaluator.php?eff_mass=3&submit=Submit |
