ProJect Phono MM: Causing Hum??

Hey everyone,
I'm noticing a hum when using this phono box.
It's usually unnoticeable when the record is playing but
i can hear the hum pretty clearly at 30 percent volume. (Which seems like low volume)

I understand that there will always be a hum but this is
obviously more than need be

Will adapting one of these help the hum on the phono box ?

 

I had a hum with my phono as well, which used a 2 prong earth the TT wall wart PSU. I finally got off my butt on the weekend and connected the T earth to a spare input on the amp. Hum is now completely gone in my case.

Perhaps this will work for you as well

 

Unfortunately im not following.

 

Instead of connecting your earth lead from your TT to the phono earth proing, clip it onto an Amplifier input instead, which will be earthed properly.
