You fixed the problem! Is the headshell metal?
Some installations may require the cartridge shield to be elec�trically isolated from the"RG" terminal. This can be achieved by removal of the ground tab.
Moving magnet hum
I have just installed an AT150 MLX cartridge after years of moving coils (thanks to the long thread). I like the sound a lot, but I have some low level hum which I have never had while using LOMCs. Could it be due to a ground loop caused by the ground strap on the green cartirdge pin? If so, please advise if it is a risk to remove and if it can be reinstalled.

@lewm The OP said his AT has a ground tab. All of the Shures that I have owned had a ground tab. Hence I quoted that from Shure. BTW, I have never seen a ground tab on any older Grados that I have owned! |
