I guess that as the recommended tracking is 1.4 - 2g and mine rubs on the vinyl at that weight that means the suspension is indeed knackered

consensus here seems to be that it's worth 75 quid for a new stylus assembly (no consensus about whether it is actually replaceable though)

KBK, this isn't the right thread to discuss this, but I'd be interested in your thoughts on the trend for minimal power supply reservoirs? 100kuF sounds good to me...

Hi, I doubt you can replace the stylus as by all indications it is a moving coil cartridge so you may have to buy a whole new one, mebbe someone on this forum can recommend a good alternative ? cheers tomcat

The assembly is replaceable, it has the cantilever,
coils etc and a four point connector to the body.

Your unlikely to get a better cartridge for 75.

A very close / better competitor would be the Denon DL110 (80).
edit - note - high output MC
As would be the ortofon MC10 Super (84 exchange).
edit - note - normal output MC

But TBH is the arm ideally suited to MC's ? I think not.

Grado's MM's are great if you like a sound more like analogue
tape than a cd tonal balance ( could do you a very good
deal on a new Black with two spare stylii)

CD like sound my favourite MM's are the Ortofon 5X0 series.
(edit - the 510 is very good value, as is the 530 due to its
better quality and stylus tip life over the 520)

Checkout cartridges at mantra audio, or cheshire audio.

Just make sure you've set the tracking weight correctly,
though to me the feel of 2g is intuitive, getting it wrong
by a factor of 2 is not possible.

But as said, the rake angle is 20 degrees, what
tracking force gives you this, approximately ?

Decisions, decisions!

I'll be getting another mc cartridge, whether or not it's a repalcement stylus for the AT depends on whether I decide to accept the 10 year shelf life. I will as you suggest have a look round Mantra.

Might well be interested in your MM cartridge - mail me offlist at chris@toby-churchill.com

cheers!

I'm confused as to minimal PS buffering. Low Z throughout a large frequency range and dynamic or transient LCR characteristics is critical for timing cues, dynamic perspective and frequency extension. Therefore..wideband , high current, and high voltage transient current draw must be STABLE and as identical as possible across as wide a frequency bandwidth as possible to have a given circuit properly trace or amplify a given circuit's input signal.

Lower uf PS buffering fundamentally defeats this purpose. It essentially crushes dynamics and creates false, accentuated imaging cues via distortion characteristics. It's a fools game. don't buy it.

Same deal for bypass caps on PS rails. That is a VERY BIG MISTAKE. Transient distortion does not equal or become 'imaging cues'. What is needed is multiple, low-z paralell run identical caps, so the bandwidth of transient current draw is a wide as possible. Same problem with complexly wound audio cables. grungy crap. Single conductor design has the most even harmonic. it can be multiple conductors but of similar or identical design.

I've been down those roads before in amplifiers, aduio circuits, video circuits, and speaker crossovers. For example, in any of our crossover designs, there are no electrolytics in use. They tend to require bypass and they alway sound bad. We use single caps of film type for all of our correction circuits even. Anything else is deemed intolerable sounding. It makes for expensive crossovers, but if every other part of the speaker design exceeds the quality of that component, then it is time for that component to be removed and replaced with something better.

Audio circuits can't be analysed by lumped parameters and the bandwith of signal condtions in all possible permutations and methods of correct analysis make it too complex a loading situation for the PS to have any odd 'resonant' harmonic distortion components to be capable of rearing their ugly head, becauseof the use of bypass caps. This is because the problems that may be possible...... WILL rear their ugly head....as the conditions for their appearance are always met, due the aforementioned complex wideband loading conditions!

The given signal in question always has a more correct homogenous sound when there are no bypass caps in use. The same goes for any other associated impedance characteristics that may be involved. Of course, this model is not strictly limited to the electrical plane of analysis either.

Anyone interested in the Grado Black with two spare stylii
and in the UK contact me sreten@hotmail.com, and reply
to this post to get me to sift through hotmails garbage.

http://shopping.netsuite.com/s.nl/c....it.A/id.244/.f

For details. In a Linn LVX it sounded nice, but the extreme
treble didn't gel well and with the rest of the system lacked
some bite. Probably as much to with the arm as the cartridge.

sreten.

Default VTA

I have the same arm on my Systemdek IIX and it has a VTA adjustment. The locking screw, which is slotted for a flat head screwdriver sits at about 5 o'clock on the arm pillar, while viewing directly from the front of the deck.

With regard to setting up I found that the VTA is just about the last thing you should worry about.
The main idea is to get the cartridge tracking correctly, which needs a simple protractor that you can grab as a download from the web to print out. Do a Google on " turntable arm cartridge setup " or similar key words.
A test LP is the ideal solution, although this costs money it's well worth it.

The difference you will hear between a well set up cartridge and an incorrectly set up one is VERY dramatic ( not this 'audiophile' type " When I tweaked the bias weight by a tenth of a gramme the highs were higher and the lows were lower, Placido Domingo appeared from between the speakers and shook my hand " type of rubbish ) and can make the difference between Maria Callas sounding like she is singing on the stage of an opera house, or singing while driving a tractor over a ploughed field with heavy weights attached to her private parts

Sreten,

I've added to your pile of Hotmail rubbish.

May your 'delete' key never rust!

Yours,

Hi Bremen

you can download at1100 manual from vinylengine.com. the at1100 series includes at1120 signet tk35e and tk50e arms and is no cheapskate armby any means.
will have more info on at30e by friday I have it somewhere and there were several at moving coil carts with replaceable stylii.

alt give me your email address and I'll email it to you. it is in pdf format. ktigerb@yahoo.com
