Back in the day I had a RD80/Linn Basik and Cyrus amplifier. There was a ground wire from the deck that was bolts to the chassis of the amplifier. The amp itself was powered by 230V AC and hence earthed. So the tone arm was grounded to earth. No hum.
I'm looking to create a new rig for my kids to enjoy vinyl sounds but modern kit all appears to be a) plastic; and b) powered by low DC voltages. I sort of fail to see the point of grounding a tone arm to a plastic phono-stage with a 12V DC supply and no earth supply ... or am I missing something?
As an aside, Flexson's VinylPlay (a heavily modded RP1?) guide says "The arm earth (or ground) is automatically connected through the arm cable screening. No other earth should be necessary." ... yet some Amazon reviewers moan about "hum". So, how can an non-earthed device ever be grounded?
