I have one of these with a Concorde 30 cartridge, an Integrated type. Follows a Stephensen curve etc. usually sounded very good. But recently I was getting bad hum from left channel especially. So I took everything over to the bench and inspected. The RCA cables were frayed and damaged. So I took apart the turntable to get at the wiring and found that the ground was going essentially
to a metal screw into plastic. The RCA out cables went to a little circuit board
and to a connector which then went to the main 4 lines from the cartridge. So i replaced the entire RCA cable, got rid of the circuit board as it was not useful, just extra connections that can go bad. There is no ground, and I wouldn't know where to ground it anyway at the turntable. It works, no hum, and the cartridge does output OK. Anybody ever had these apart and have some input?
Now I have to put it back together.
