Turntable hum??? Help


Just getting back into vinyl, and seem to be getting a hum that increases in volume as the passive preamp potentiometer is raised in volume. Played with ground wire from turntable to phono amp with no luck, and was trying to see if any of the tonearm wires were bad and can see nothing wrong or loose. Could it be the solid state phono stage and it's power supply? The table is a Well Tempered and the phono stage is the Gram Slee 2 SE. Any help would be appreciated!

Thanks!

Red2,

I also have a WTT.

Make sure that the ground wire from the ground screw on the rca bracket to the arm is intact.

If you have tried the above suggestions and still have the hum, connect a wire from the ground screw on the rca bracket and touch the motor.

I also have a WT which had a pad connection from the cartridge clip to tonearm wire. It looked OK, but poking all four wires behind the cartridge, found the one which was the culprit. Simple re-solder is all that was needed.

Good Luck
Jim

What phono cartridge are you using? Grado cartridges are well known for "humming".
