Phono stage hum


Dipping my toe into Tubes for first time.

Have been using simaudio moon lp5.3 phone stage.

getting what sounds like ground loop hum with the chinook and my thorens 160 super... tried with a different turntable (cheap teac) and no hum....

any ideas?

Try using a cheater plug on the amp. This removes the ground connection and therefore the loop. 
Check all the ground wires inc the one on the chassis. Run a test wire from the Chinook ground lug to the chassis to see if it resolves it.
