I got the warning this morning, but now I don't. Good job!
Doesn't sound like a ground loop issue. If you haven't done so, you really need to clean with Tuner cleaner or Deoxit. We're talking a good soaking and working ALL controls, not just slides. Don't focus on just the left, do all banks and switches and whatever other controls there are. You won't be able to to do anything about electric relays as they are usually sealed and don't need attention. Everything must operate smoothly and EASILY.Long time reader, first time poster.
I have a Technics 1200 MKII hooked into a
Sansui RZ9500av &
Techincs SH-50 GE
I finally got the graphics equalizer hooked up, but now I hear a crackling noise from the left speaker. I've read up on ground loops and tried some simple fixes to no avail. I tried a different speaker to make sure it wasn't blown, everything was fine there. The crackling noise is only present when the graphic equalizer is turned on. Anybody have any hints?
For $600 Tullman that thing better do more than get rid of a gound loop!!
Try this for $59. Hum-X Ground Loop Hum Stopper from Markertek.com...it worked for me. It appears to be more of a musician's unit, but it works great for tube amps.
Ground loops are really a major pain...you can search for hours with nothing solved.
I had the same problem with a ground loop between my house ground and the cable ground. I put a 3 to 2 prong adapter on my home-make amplifier and the hum was gone. The cable box is now the sole ground in the system (through the coax cable).
First: The outside electrical earthing rod has nothing to do with the system ground. It is an earthing conductor whose sole purpose in life is to protect you against a direct strike. It provides a path for a lightning bolt.By grounding your equipment with the signal cables connecting the pieces, would a ground loop occur if you were to connect the equipment also from ground post to ground post and then to a true electrical earth ground (a rod buried 6')outside?
Hum X is the real deal. I had a ground hum I could only get rid of by lifting the ground and I was not comfortable with that so I purchased one of those noted in the above message. $75 well spent in my opinion.

It could be radiation of an trafo in your power chain or maybe try to swap the power connector 180 degree. Sometimes this can do the job...
