How to keep your stylus needle at peak performance

new-stylus-tip-cleanMaintaining your stylus needle properly is important to prevent performance degradation and lengthen the life of your records.

A client recently sent us an £800 cartridge, requesting it to be checked for a manufacturing fault because it had suddenly ceased to perform it’s usual magic. We duly had the cartridge inspected by the importer, only to be told that it was in fact fine. The problem was due to a very small but tenacious lump of gunge which had attached itself to the stylus needle. Once removed everything behaved perfectly.

This story is an example of where performance degradation was dramatic. However the same thing can occur slowly over time with a stylus which is not maintained well. In which case it‘s not so easy to recognise the change in performance.

To understand the best methods of stylus cleaning without causing damage, you want to hear from a seasoned authority in the field. There should be a health warning attached to some of the stuff you read on the internet. Credit for the below information must go to John Burns who distributes Dynavector cartridges in the UK. John has seen and tested countless used cartridges for many years since his early days of working for Linn and then starting up on his own. He also has complete access to cartridge manufacturers and has developed an intimate knowledge of the subject. 

The following information is provided in good faith and we cannot take responsibility for any damage that may result - if you are in doubt about some of the more tricky aspects then it may be wisest to get the job done by a dealer you can trust.

Ensure records are truly clean

At risk of stating the obvious, it is essential to clean records properly.  The story above was almost certainly caused by a record purchased from a 2nd hand shop which had a small smudge of something tacky on the surface. Either way, only liquid cleaners like L’Art Du Son will remove this sort of contamination and even then unusual contamination may need specialist treatment.

Clean your stylus needle using appropriate methods

Clean your stylus tip regularly with a good stylus cleaning fluid and brush. How often, depends on how clean your records are. There are a number of proprietary fluids on the market but steer well clear of anything containing iso-propanol, as this can slowly dissolve the glue holding the stylus needle into the cantilever (depending on the brand of cartridge). Be careful to use a fairly flexible brush and always pull the brush along the stylus in the same direction the record travels. Also use fluid sparingly as it can degrade the rubber suspension inside the cartridge if applied too liberally ( fluid can flow up the cantilever by capillary action).

Inspect the needle visually

The tip of your stylus needle is so small that it can only be seen properly with a powerful magnifiying glass or microscope. I use a 20X magnification glass or 60X mini microscope if better inspection is needed. These items are relatively inexpensive and can readily be purchased on the internet.


When you examine the stylus, the side of the needle tip should be slightly convex in shape with a smooth glass like appearance. If the stylus shape is concave then the tip is worn and should be replaced. Any deposits (usually black) need to be removed. There are a number of tools in the arsenal that you can use to achieve removal. We will start with the mildest and move up with increasing severity.

Removing deposits.

Brush with Fluid

This has been covered previously.

 

green-stuff-stylus-cleanerGreen stuff paper

This paper is a very fine aluminium oxide abrasive paper that can be gently drawn under the stylus to remove embedded dirt. Diamond is so hard that it is not affected by this but it is amazingly effective at cleaning stylus tips. “Green stuff” used to be readily available in audio shops free of charge but is now hard to find. The only word of caution is that if your cartridge has a microline tip (usually only found in high end cartridges)  then it’s probably best not to use it - these are so fragile they might break. If you wish to order this, see link Green Stuff Paper

 

Cotton bud and degreaser

The gunge in the above story was removed using a cotton bud with a water soluble degreasing agent dissolved in distilled water. One needs a very steady hand to carry out this sort of operation. The idea here is to bathe the tip of the stylus in a liquid which will dissolve the offending gunge into solution which is then absorbed by the cotton bud. The cotton bud must be very gently dabbed vertically on to the stylus without causing the stylus any horizontal movement (i.e no movement from side to side or forwards and backwards) and virtually no vertical movement. L’Art du Son record cleaning fluid is good for this but there are many other alternatives such as "Last" or Lyra cleaning fluids.

It’s best to keep all fluids, especially alcohol based, away from the damper rubber or 'cartridge internals' as they will deteriorate quicker. Stylus fluid should be used sparingly. One of our staff illustrates this technique in a 2 minute video video here.

FURTHER REMARKS ON MAINTAINING YOUR CARTRIDGE STYLUS

Cleaning cartridges and Stylus tips is not just a quick read and away you go - it is important to understand all the issues to avoid incurring costly damage from common mistakes.

It's easy to hear the difference between a well pressed record and a worn record. No matter how good your system is, there is no recovery from a worn record. Because record deterioration takes place over a period of time, it's all too easy to miss the vital difference that cleaning will make to preserving long term sound quality.

There are a few misconceptions that surround this area. For example some think that it's just the stylus tip that causes damage. Others think that special tip profiles help protect records.

The lethal enemies that can slowly destroy the quality of your records

A well maintained Cartridge in good condition, can be the difference between great sound quality and appalling sound quality. It's the difference between fast deteriorating records and those that maintain their quality for 3000 plays.

A cartridge in good condition will cause very little wear on your records. Most damage is incurred through one or more of the following:

  • A dirty stylus needle
  • An aged cartridge suspension
  • A worn stylus
  • Dirt on the record
  • Poorly set up cartridge
  • Poor quality deck or tonearm

We want to shed more light on how to ensure that your cartridge performs as it should for much longer than normally expected.

A Poor quality tonearm – Tonearms that resonate badly or have bearing “chatter” will cause the cartridge to “bounce around” the grooves in ways that they are not supposed to, and cause slow degradation. The difference in surface noise of a record between different tonearms and cartridges is a big clue to how differently a stylus handles the grooves. It would be a mistake to equate low surface noise with high performance but it can be an indicator.

Incorrect tracking force – Some people in attempting to reduce record wear have minimised the specified tracking force for their cartridge. The truth is that this stops the stylus sitting securely in the grooves and actually increases record wear – It's always best to just stick with the manufacturers recommendations.

Cartridge life and care

Normal advice says that the life of a cartridge is between 2 to 3 years or 2000 to 3000 hours of use. The truth is that this figure can easily be doubled by applying little known techniques. If you are using a cartridge costing over £300 this represents a big saving over the years.

The life of a cartridge is dependent on 3 factors

  • Stylus wear – even diamonds wear down if records are contaminated

  • Suspension ageing

  • Proper care and cleaning of the stylus tip – an unwitting approach here will reduce the life of many cartridges.

Stylus Wear - The thing that causes wear, is dirt on records which acts like an abrasive. Cartridges that are taken care of and played on cleaned records can easily last 5 to 6 years with no detectable diamond wear.

Suspension Ageing - The stylus on a virtually unused cartridge can be perfect but if the cartridge is old, then the suspension can be useless and the performance has disappeared. Worse still, the suspension tends to stiffen up with age and cause damage to your records. I know this from personal experience of using an Aged (high end) cartridge which proceeded to wreck my record collection one play at a time till I realized what was happening. How much the suspension deteriorates over time, varies a great deal from one manufacturer to the next . The type of material used in the suspension determines performance and ageing. The better suspensions tend to deteriorate more rapidly and 6 years is really the maximum for many. If the wrong cleaning fluid is used or excessive amounts are allowed to get on the suspension the same problem can occure.

Only the Cartridge manufacturer can tell you how long the suspension is likely to last. You can predict that a Dynavector will last up to around 6 years . We cannot speak for others, as manufacturers change their designs and it is impossible to safely keep track on the hundreds of different models on the market.

If your cartridge is damaged or old

If your cartridge is really old then this article may have raised the question of cartridge change. Once a cartridge's usefull life has expired there are three main options

a) Order a different cartridge.

b) Order an exchange cartridge for your existing model – This is a safe method and saves you 20% on finances providing you are ordering the same brand.

c) Order a stylus replacement - this option is only available for budget moving magnet cartridges as a rule, and is only probably worth it on a relatively new cartridge if your cantilever is damaged (bent). On an old cartridge there can be a lot of debris that has been "sprayed up", as the stylus traverses the record. This debris remains in the motor mechanism of the cartridge even if you change the stylus with it's suspension. In our view this represents a false economy as an exchange cartridge is not a lot extra and well worth it..

d) Find a reconditioning service to re-tip the stylus and replace the cantilever suspension - Many people ask us where they can have their cartridge re-tipped or rebuilt with new suspension. This is a very tricky question as whoever you go to, will not be party to the exact material used in the original cartridge and hence the result of a rebuild can be vastly different from the original. Cartridge manufacturers do not offer rebuilds, they offer exchange. By using a 3rd party it may appear that you are saving money but there is no way of knowing the quality of what you are getting and we have widely varying reports on the results.
