Hum question

When I engage the start platter button and play an Lp...hum is minimal...however when I stop the platter...it becomes quite aggressive...not using a Grado cart...simple budget phono staged no adjustments...any thoughts?...stage too close to turntable?

ah, ok, Stringreen, now I undesrtand.
and I must say that I already made that attempt (exactly the way you describe it, except that it's eaasier with italian plugs, which have equal prongs), unfortunately without success.
thanks anyway, ciao.

OK Daniele...now what I would do is plug the phono into a high level input of the preamp which eliminates the phono circuit..testing it this way, make sure the volume is way down and slowly bring it up to see if the hum is present there.
