Expert Stylus Company
STYLUS REPLACEMENT SERVICE FOR ALL TYPES OF CARTRIDGE
This is a very specialised service and one which was started by our company over 25 years ago. As manufacturers of the largest range of diamond and sapphire styli we can offer clients a very technically sound service.
HOW IT WORKS
With the very high cost of replacement styli for the more expensive range of magnetic and moving coil cartridges considerable savings can be made by replacing worn diamonds with diamonds of a similar profile and mass. Where damage has been caused to cantilevers, providing the suspension and coils are undamaged, new ones can be fitted. It is necessary in the first instance to carry out a very careful examination of the cantilever system and all other components in order to assess whether the eventual work carried out will prove satisfactory. Once this has been done, you will receive a detailed quotation together wSth our recommendations.
All work carried out is guaranteed and any client not satisfied will have their payment refunded. It is true to say such occurrences are rare as we have a well equipped listening studio with the very latest technology.
It will be appreciated with so many different makes of cartridge, it is impossible to give a quotation without knowing the model you are using. We are however, familiar with most makes, and if you would care to write or telephone, we shall be able to give costs.
When forwarding cartridges or styli please ensure they are packed either in the original packing or in a suitable manner so that no damage can come about during transit. Moving coil cartridges are very easily damaged if inadequately packed.
Apart from stressing the importance of good packaging, it is also essential when forwarding goods to complete the Customs Declaration correctly otherwise delays and unnecessary import duty can be incurred which would have to be charged to the client. Be sure to state the goods are "FOR REPAIR & RETURN".
LATERAL CUT 78 R.P.M.
Our experience in manufacturing styli to play early acoustical and electrical recordings is extensive. During the last 20 years we have been producing diamonds and sapphires with varying radii and profiles in an effort to find the optimum to reduce surface noise. We have received considerable assistance in our research from record companies, record archives, broadcast companies, private collectors, musicians and universities.
Our recommendations for records made within the following perlods are as follows:
.0040" (90 microns)
.0040 x .0012"
1920 - 1939
.0035" (80 microns)
.0035 x .0012"
1939 - 1966
0028" (650 microns)
.0028 x .0009"
It will be noted we supply other sizes of diamond of a smaller radius. These sizes are at times most useful where records have not been subjected to continuous playing with steel needles. The reduced contact area results in a quieter background.
We manufacture replacement diamond and sapphire styli for most makes of phonograph including Edison, Pathe, and Columbia. The styli can be supplied mounted in bars or, alternatively, we can re-furbish clients own which we feel is so much better as it ensures the machine retains an original part. Pathe sapphires are supplied mounted in brass shanks. Columbia sapphires can either be supplied loosely or mounted in aluminium domes ready for cementing to diaphragms.
ELECTRICAL REPRODUCTION: LATERAL AND VERTICAL
Those clients wishing to play records, discs and cylinders electrically can do so by using a cartridge fitted with the correct stylus. It is important the cartridge will allow tracking weights up to 5 or even 6 grams. For normal lateral cut records a tracking weight of 3 grams will be adequate. For centre start Pathe discs and records in poor condition extra weight will be necessary. It will also be necessary to wire the cartridge for vertical response only otherwise noise from the lateral channel will be experienced. This we carry out for clients.
DECIDING WHETHER TO USE CONICAL OR RI.LIPTICAL TRUNCATED DIAMONDS
The condition of records will dictate whether to use conical or elliptical truncated diamonds. Records in good condition will reproduce with greater analysis and reduced surface noise if played with elliptical truncated diamonds. Records that are visually poor in condition are better suited to conical truncated diamonds.
The quality control within our laboratories ensures a finished product of the highest order. Over the years we have seen dreadful examples of workmanship which can only result in the destruction of precious cylinders and records. Do bear in mind, diamond and sapphire components cannot be manufactured cheaply and it really is false economy to use inferior materials.
