Please help diagnose sudden turntable problem

Hi everyone,

I just encountered a very sudden problem with my turntable. I have a fairly new Marantz TT15s1 that was sounding great until yesterday afternoon. I noticed an unusual amount of static, but I chalked that up to the dry air from running the A/C for a couple of days. I used a zero stat gun, and that seemed to help a bit.

Today, however, the problem got significantly worse within the span of a couple of albums. Now, I have significant static and distortion, sometimes completely obscuring the music. It sounds like an amp being overdriven. I have tried two different phono amps and two different preamps, but in every case I get the same sound.

The Marantz has a captive tonearm cable, so I can even swap that out. It's a Clearaudio Virtuoso cartridge that looks to be in excellent shape. The stylus is not bent or damaged. All the leads are plugged in securely. I'm at a loss.

Any ideas would be welcomed. Thanks!
Scott

Mapman,

It seems like a damaged stylus is the only possibility left, no? Unfortunately, the cartridge costs almost as much as I paid for the table, so I'm not quite ready to spend that much shortly after purchasing it. I suppose I could buy a cheap cartridge to see if the static is still there and then get the more expensive one if it solves the problem.

I've been on a terrible run of bad luck with new gear my last five purchases - turntable, amp, integrated amp, phono amp, and stylus gauge - all were either defective out of the package or broke down within a week. I've spent a fair amount shipping brand new gear to be fixed. This turntable has lasted a couple of months, so that's progress...

just saying... possible interconnect issue. Have you tried alternating these or changing them out? Do you have any tube gear?

Gruv Glide will completely eliminate the static issues. There are some people who are vehemently against putting anything on a record, but many people use it with no problems. Just use as directed and your static issues will be over. Of course, it may be something else altogether.

My experience with Gruv Glide:

(1) In order to hear an improvement, you have to have a very revealing system
(2) This improvement isn't of a nature that over-rides the following negative aspects
(3) The application method (a fabric pad)+(this inherently is a source of static energy)
(4) If you can't find a way of putting but a few drops on the applicator pad, you will have put TOO much on your precious vinyl. Your stylus will pick this up and show it to you as a black blob on it's next visit to a Zerodust cleaner.
(5) The slight sonic benefit, to me, isn't worth the trouble or the cost.
(6) Bad investment... other more important issues await.
(7) I vehemently disagree with Chayro here!

Slaw - I've tried both tubed and SS gear, and I get the same problem. The only interconnect I haven't changes is the captive tonearm cable, and if that's the problem then I'll have to have the tonearm rewired.

The static seems somewhat less problematic when I use SS gear rather than tubes. Other than that, I don't notice any difference regardless of what I do.

I may have the chance to swap in an older cartridge later today, so I'll keep y'all posted.

Thanks, Scott
