I've have had this turntable since '73. It was not being used much and so recently I went through and replaced the 'hair' tonearm wires with the correct gauge and color...what a crummy job. Then I replaced the RCA cables with new. All of this improved the sound quite a bit. What I have now is hum. I can turn the gain all the way up on my receiver and there is almost no hum. But....turn on the platter and there is significant hum. I don't remember this ever being a problem before and I can't really blame the cart, because it's only when the turntable motor runs. I tried to ground the motor itself but that only increased the hum. The ground I have now comes from the two cart shielded grounds and goes to the grounding lug on the receiver. I'm wondering if it's the motor itself, something to lube or some cap gone bad related to the motor? Maybe somebody had had this same problem with this series turntable?
