Stylus/cantilever stiff and noisy--WARNING!


If you can hear the music from the needle (at the needle/cart) when volume is minimized, cue the tonearm up as soon as possible.

The suspension elastomer on the stylus has stiffened up and will not only sound poorer but can damage the grooves because of lack of compliance.

I've had this happen a few times and it seems to happen very quickly. Literally, a week or two after last playback.

This usually happens with older styli or new-old-stock styli or carts.

I was able to get a an ADC (1977) stylus working after a wd40 treatment (this is common "cure" for the issue). But the problem came back very quickly.

A "feel" test (fingers on stylus) might  also help get the "feeling" for good compliance vs. bad.

I had this happen again on some new-old-stock Shure replacement styli.

I'm not certain if there is some sort of test or "rule of thumb" that us vinylphiles can use to:

(a) ascertain it is indeed elastomer/suspension related

(b) gauge the ORIGINAL mechanical compliance of the stylus.

Maybe comments related to following might be useful :

Shure , Stanton or Pickering stylus are stiffer than other manufs.

DJ cantilevers are stiff.

Mass of tonearm vs stylus compliance.

Thx!

btw,

This discussion makes a strong case for playing with the dust cover either raised, or removed, as the vibrations you hear can be reflected onto the surface of the LP by the dust cover if lowered/closed/on. 

My dust cover lifts off, it’s big and heavy, I have a designated place in front of the Reel to Reel player for it, and put felt squares on it to protect it and prevent any vibration from the speakers/floor 

Notice the Plants. I promised Donna the top of the rack for plants when we bought it. Then I had to get clever. I made two large trays, painted black, glued thick felt bottoms, and one stays put, the other one moves, either on top of the TT Dust Cover, or temporarily on top of the Tape Deck when playing LP’s.

IF you leave the cover on, raised during play, then make sure the TT remains level when the cover is up, as the weight shifts more to the rear feet. If needed, re-level, and re-calibrate the arm/cartridge after that.

 

A lot of rubber parts are sensitive to ozone exposure.  You would have to seal your cartridge in an air tight container to reduce exposure to this pollutant. There are cartridges that seem to be relatively immune to the suspension going bad from sitting around.  Koetsu cartridges, for example, can be quite old and still work perfectly.

It's amazing that phono works so well (or, by comparison, maybe digital is so much inferior from the get go ????) ... anyone have to adjust their VTF because they are above 7,000 ft seal levels? Etc.

Suspension rubber getting hard with age IS an issue, but, I have not experienced nor heard of this problem being manifested by increased needle chatter.  It is usually heard in the signal itself--mis-tracking, buzzing, etc.  

I think most audiophiles --like the Audiogon community that are not really into budget gear, thrift or ebay cheapies, or DIY -- change gear or upgrade components way before stuff like  cantilever  suspension or dried out electro caps are noticeable issues.

That said, some of that late 70's stuff is quite desirable. Much of it was designed in the lab AND voiced by ear ... all very deliberately and with passion, and in the listening rooms of Sony, Pioneer, Marantz, Shure, Empire, Radio Shack, etc. Yeah, when it works like new, it holds its own.

Hollowman, The cartridge is microphonic BECAUSE it is a transducer.  I did not use that particular word, it's true.  So what?

If there is significant ozone in your regular listening environment, you ought to be protecting more than just your cartridge.
