My other Fergie TT sounds fine !
Off with the bottom and take the metal plate off from under the arm , that covers the larger RCA wire solder joints to the tonewire arm.
Putting the multimeter at 200 ohms on the red wire and out to the point of the RCA plug , and it never goes down to 0.35 , whereas the other 3 do,( two earths and the white) . In fact if you move the plug about it goes from 1 to 13.00 Bad connection
The RCA plug is a moulded one ,but in a minute its getting cut off and redoing it with a new one
I only ride 'em, I don't know what makes 'em work
