More valuable info that might support the claim that the hum comes from the TT:
When I disconnect the small connectors of the cartridge, the hum is gone.
I verified continuity of all 4 wires:
1. Red to + right
2. Green to - right
3. White to + left
4. Blue to - left
All are ~ 1 ohm.
Why is the cartridge producing this hum then ?
