Electrical problems?

It sounds like somewhere (probably associated with the tonearm mechanism) there is a loose or intermittent ground connection. Does it sound sort of like the popping you get when you plug interconnects into your preamp while the volume level is up and the amp is on? (Well, we were all young and stooopid once!) You'll have to check your tonearm out carefully. Does this happen in one or both speakers (I'm wondering if it's the tonearm internal wiring or perhaps a cartridge lead or clip)

I have checked the cartridge clips and their connection appear to be allright. As far as the internal wire of the tonearm I haven't ventured to dissasemble it. I could try and use another arm wand and discard the wiring in the arm wand as the one causing the problem. Then I would have to open the pivot - the ET2 is a linear tracking arm. The disturbing sound that the speakers make can be similar to the change of interconnects when the sistem is on and set to the component being affected but then I am willing to state that at least there are two different types of sound. The other one that I have detected seems to have a pure electrical nature in that it is not a tap sound per se but instead has some variation in its development. Something interesting happened, that I tried to connect another amplifier and a second pair of speakers in another room but the power amplifier showed a current overload signal in theright channel and then the right channel got shut off, probably a fuse broke. I had a similar experience with this second amp but with another preamp but in that occassion the event involved cd playback therefore this second amp may have something wrong going in its right channel. What's interesting about this is that after its right channel got shut off I switched the preamp to monophonic operation and a continuos burst of sound started to come out of the speakers that wouldn't stop until I set up the preamp to stereo operation. Therefore there could be something wrong in the right channel some where in the L.P. system.

Alanpiga,

I don't know if it's relevant to your noise, but how did you ground the Teres motor pod at the motor end? Grounding the case does not ground the motor.

There was a discussion of this recently on the Teres discussion forum. Chris Brady chimed in to offer an effective method. I'm afraid I don't remember the details, so I'd urge you to join that forum if you haven't already. The discussion would be in the archives, no more than two weeks ago.

I spoke to Chris at Teres and his suggestion is to connect the wire from the screw at the bottom of the table which I believes connects the bearing to the power adapters ground.
But he suggested that it may not be possible to eliminate the static building up from the platter altogether. He also suggested me to use silk thread instead of the rubber band that I am using. I am getting some in a few days and I will see if it has any effect in the static build up. The most upsetting situation would be if this static build up has an effecr in the second amp that I want to install and then I won't be able to install it, due to current overload of right channel as the amp signaled and then got shut off, as I metioned in the former post.
