More turntable set up problems

I have an older Teres Audio turntable, purchased in 2005. It is a basically a model 160 with some upgrades, such as a birch plywood platter, a Teres VTA adapter and a hardwood reflex clamp. The tonearm is a Moerch DP-6 Precision red dot with a 12"armtube, and the cartridge is a Zyx R100-02H. I had everything set up in 2005 and everything was still working fine when I stopped listening to it a few years ago. Just this month I decided it was time to start listening to my two channel system again - I really do regret having neglected it for so long, but you can't change the past!

The turntable is level, the VTA appears to be correct, I have aligned the cartridge with the use of a Turntable Basics protractor( the only tool I have for this) and the tracking force is set within the range suggested by Zyx. With the rather crude measuring devices I have (rulers/straight edges) the overhang seems about right - it is supposed to be 13.3 mm, but I have nothing that will measure .3 of a millimeter. Anyway, I don't know how accurate my eyes are but I think I have things set up as close to where they should be given my tool and eyesight limitations. But.....

The sound coming out of my speakers is awful.....lots and lots of distortion, sounds like a transistor radio turned all the way up, if you know what I mean (if you are old enough to have been around transistor radios, lol,) hissy and garbled, really rough.

I have tried adjusting the anti-skating on the tonearm. The Moerch DP-6 has a lever for this, not a wheel, so I can't actually dial it in, but moving the lever made no discernable difference, the system still sounded like you-know-what. I also played with the VTA, just in case, but again, this made no difference.

I am probably going to start all over again and recheck every alignment, etc., but if anyone can give me some tips as to what area I should definitely focus upon - azimuth perhaps? - given the distortion problem my system is experiencing, I would much appreciate it.

By the way, I have a DAC and CD-player in my 2-channel system as well; CD's sound wonderful, so that SHOULD eliminate the possibilities that the DAC or tube power amp are causing the problems. Of course, there is a tube phono-stage/step up in the mix as well, but I really don't think that is the source of the problem - I really think I have done something wrong with the cartridge alignment....

You could have a bad tube(s) in your phono stage. If you haven't used the rig in a while, the cartridge might have dried out, (the rubber elasticizer that holds the cantilever in) which will impede the movement. Make sure you clean the stylus well.

I would also clean the spindle off and reinstall fresh oil to the bearing.

Good luck and let us know what you finally find out.

Oakiris...I live about an hour away (Northern Colorado) and happen to be a turntable (and tube) guru.

It would be my pleasure to drive down and help you get this fixed. I have all the tools (and a few drawers full of tubes) and some turntable bearing oil, so we should be able to get everything up and running for you.

Unfortunately, I probably wouldn't be able to get down there until after the holidays...sorry.

If you would like to take this offline, (well off of Audiogon anyway), please email me at mraudioguru@gmail.com and we can discuss it.

Holly...it was my pleasure to come down to Denver and help
out. Sorry we couldn't get you up and running in that
single trip.

To further update everyone, we swapped out all the cables,
(except the tone arm DIN to RCA cable, but we did remove and
reinstall it to make and break the connection a couple of
times). We also swapped out the phono stage with another
one. I tested all the tubes which were all at or above new
level. We trouble shot it all the way back to the
beginning, like you really need to do.

The weird sound just didn't sound anything like a set up
problem. So after all of the above, I pulled out my loupe
and sure enough the stylus, (diamond tip) was almost 180%
twisted. It was on top of the cantilever instead of the
bottom!

I first used the loupe to see the cartridge in action and
noticed very small shavings of vinyl coming off the record,
that's what made me take the arm wand off and look very
closely at the cartridge. I told Holly I hoped the LP
wasn't to damaged. We really only played it for a few
seconds each time.

She has a wonderful system with some really nice gear. I
told her we all should fine her for not using it for quite a
few years. She might lose her "Audiophile" club
card :-)

Overall a very pleasant adventure. I love talking audio and
music with fellow followers.
