The Technics Turntable Fan Club - Questions, Advice, Discussion

quick update....moved amp and turntable (both) to another room...with all hooked up no hum.....but....the technics still had that slight crackly hum with the head shell off. Technics finally said that it could be an internal issue. Sending it back for another and we will see.

of note...the AT table did the same thing, but to a much lesser degree. if this was a $350.00 table i could live with that, but it is not.

so will now attack the rack when i have some time...bought a new Furman power strip to replace an old one i was using.

Just curious…. Why would one ever have a turntable powered on without a headshell attached?
 
good question...actually it was powered off but amp was powered on...if i am not mistaken, it should be a closed circuit without a head-shell on if all is grounded...which in the test, it was. So, it should not hum...no?

The signal down the tonearm would come regardless of power because the power is powering the motor rather than the tonearm which is getting its signal from the cartridge generator. So once the phono stage is on you’d get that regardless of the turntable being powered on I’d imagine because the ground the the amp is grounding the tonearm tube itself?
