Sounds surprisingly nice with properly adjusted AT95e cart tracked at 1.9 gram (19 mN ).

 

 

This is a photo promised quite a while ago; first read about this/similar in The Absolutre Sound of the day, in review of Sumiko Analog Survival Kit - where something similr was included:

 

Here the close-ups of the "knots" that hold the stretched foam rubber string in place; NO glue whatsoever

 

 

 

 

Here the material "string" has been cut from with normal scissors  -  the usual foam rubber profile for stopping leaks in doors/windows:

 

 

Please note that whatever "glue/threads/etc" on the flat surface that is otherwise self adhesive mounted to door/window frame, must be removed for our purpose prior to mounting to the arm tube.

 

The purpose of this "string wrap"  is to damp the resonances in the arm tube usually made from metal and sounding, you guessed it, quite metallic.  Although it makes biggest sonical benefits with lower priced vintage gear, its use is by no means limited to those only. Some high mega zoot price designs also showed marked improvement(s). Without going too much into specifics, it will sound quieter in the groove than normal - and that alone is worth a lot.L3000.gif

 

It is very light, adding approx 0.6 gram change upon rebalancing the arm - do not forget to rebalance the arm and  set the VTF you normally use.  The string is wound under as high reasonable tension you can achieve/are still comfortable with. If arm has removable headshell,it is advisable to remove it. If the cartridge has GOOD STURDY stylus guard (not flip guard or anything possible to remove with light force ), you can use this. If you intend to try "string wrap" on some arm sporting unprotected nude naked cartridge  named after bird with a hefty price tag - REMOVE IT FAR AWAY and remount only after your string is securely in place on the arm tube... Goes for ANY cartridge you mind demaging.

 

If your arm has sensitive bearings, it is necessary to remove tha arm from the table, apply the "string wrap", and then remount everything back together.

 

Please note that I do not assume any responsibiluty for your equipment - this is only general suggestion and you are on your own regarding implementation.

 

How can it sound? biggrin.gifgs1000.gifwink_face.gifetc

With the standard Baerwald alignment, nearly every cartridge I've installed on my Tech 1200 has been virtually to the tip of the headshell. When you search for alignment tips, many Tech 1200 owners recommend starting at the farthest position and working backwards. Seems counterintuitive, but it works.

All turntables I adjust get measured with test records and an oscilloscope - any misalignment has absolutely no chance to hide.  They perform as they should.

 

Needless to say, it sounds good.

 

If anyone starts now with various alignments, I will say then get a linear tracking arm. It can be topic for debate, but only if and when you have actually (had ) your cartridge measured for deviations from perfection. Actual styli errors far outstrip differences among alignments and only small percentage of actual styli of any given model at ANY price earn from me suffix T - which means Tangential and is perfectly aligned in each and every plane. For this reason, deviations from perfect adjustments have to be used in real world to compensate for stylus error - without test records and at least an oscilloscope, Mission Impossible.

 

And some perfectly made actual adjustment of real cartridges actually do look horribly wrong - particularly those for azimuth. Picture yourself how skewed a 3 degree error in cartridge looks like on the mirrored surface  ...and it is not that rare in practice at all. The goal is to get playback stylus positioned as close to the position cutting stylus made the groove - it is all that matters.

 

Should I try to move the cartridge back some? This is the only cartridge I've used on this turntable actually, although I am probably going to upgrade to a Denon or Grado (or something else, I don't know yet) cartridge sometime soon. When I installed it first it seemed to fit most naturally that far up. It sounds pretty good, so I don't think it would really make a difference sonically.

You will see all that will be needed will be slight angling the cart towards inside to the main TT bearing . This tool is the best bang for the buck - there are better and more precise that without any knowledge, just by observing instructions do the trick - at approx 10 times the price. Look at the Turntable setup thread, there are all the references needed to correctly set up the geometry for the pivoted arm.

As far as aligning a Technics cartridge goes I've gone by the old manual for my SL-B2 as well as other sources for Technics stuff and gone with the 52mm from stylus tip to rubber washer on the back of the headshell method. I bought an overhang gauge from needle doctor (KAB USA sells them too, for cheaper actually) and use it as a baseline, though with mixed results.

That's for the information, I'll try the 52 mm rule and buy that tool as well.

My Denon DL110 cart sticks out on my sl1200mkII as well, it's about where you want it according to Baerwald method.  I just set up two different cartridges on mine this weekend, I used the alignment chart from Vinyl Engine, you can print these out, you have to make an account is the only draw back, but it is free, so that's cheap enough.

 

http://www.vinylengine.com/cartridge-alignment-protractors.shtml

 

They have one specifically for 12/13/14/15/16xx series tables with an s shaped arm, it's what I used, and I feel I've had decent success with it, maybe when I get a few more bucks in my pocket I'll order some fancy gauge or what not, until then paper copy will do.

That sounds interesting, I might have to try that on my SL1200 knock-off table (the arm geometry should be the same). Technics used Stevenson which is what the 52mm alignment method comes out to. I've never tried Baerwald but I'm happy enough right now. Only minimal amounts of IGR at best at the end of records I've bought brand new. And before you say anything about the knock off (it's a Gemini) it out-performs my SL-B2 in tracking.

Only thing I'd say about the knock off is maybe not use the sl1200 specific gauge, and use a generic version (also on that page), just in case the arm isn't exactly the same.

That's a good idea. I've downloaded the turntable's manual and it says absolutely nothing about how to install the cartridge properly (helpful, right?). The arm, while most likely inferior to an SL1200's has the same measurements and the head shell's are virtually interchangeable. Until I decide to try something different like Baerwald I'm actually pretty confident that the Technics Overhang gage is getting me as close as possible to Stevenson. I'm a digital guy so my patience for this stuff is a bit low but I do have enough records to justify keeping the capability around.

A bit off topic, but this seems like a decent thread to ask in.

 

I have the chance to buy 2 Numark TT1625 turntables and a DM950 dj mixer for around $150.  I'd be strictly using them for djing, not scratching and all that, just playing records at local bars.  I have no familiarity with Numark, and the reviews I've read seem to be coming from people using them for scratching and beat making, most of them seem to call them beginner decks for that sort of thing.

 

Has anyone used them for just playing records?  If so what did you think?  Obviously they're not "audiophile" by any means, but they don't need to be, and if I can use them to generate some cash, then I can sell them and buy two more SL1200's.  I just don't want to buy a pile of headache.

Gemini PT2000. S-arm. Direct Drive. Quartz Lock. Pitch Adjustment. Cue Light. DJ lamp. Grado Green cartridge. I hate how it tracks and really want to try the AT95E. ART USB Phono Pre preamp. I added a bulls-eye level. No dust cover. Need to make a maple base to further isolate it from any vibrations. The overhang gauge I got from Needle Doctor is over in the corner with the Technics SL-B2 head shell in it and an AT3600. Just cleaned a Leonard Cohen record and it doesn't sound as bad as a lot of old records I've come across do. Will probably add this to the Good Records Milk Crate. Alphabetized and all.

I have the ART usb preamp, its actually really nice! I have yet to use it to transfer files but I'm happy knowing it can.
