Here at West-Tech we carry a large assortment (1000's) of needles for both the older record players as well as the new. We have the ceramic, magnetic and crystal types. We examine all needles under a microscope prior to sending them out. They are also tested on our high tech console tester record player unit.
We also supply the "bent shank 3 mil" osmium, sapphire and diamond needles for the old 78 RPM thumbscrew crystal cartridges. We also have the "bent shank 1 mil" for the 45 RPM. (See photos below; click left photo to enlarge it).

ZENITH COBRAMATIC OSCILLATOR TYPE CARTRIDGE/NEEDLE
The Zenith needle/cartridge in red, green and red/green for the Zenith Cobramatic which utilize the oscillator tube to operate are almost extinct (See photo below under Power Points). In the event we cannot supply this special cartridge/needle, here at West-Tech we can install another ceramic cartridge with needle in your tonearm, bypass the oscillator section of the amp to bring it up to proper specifications. Email or call us about this service.
In case you don't know the correct needle for your cartridge, call or email the name of your unit and model number. In some cases you may have to send in your cartridge to have us install the proper needle. (Click on the Needle thumbnails below.)
Enjoy your tour of our needle page and let us know if we can be of assistance. Gib & Linda
Hints on Needle Life
How long will a phonograph needle last
and how will I know when it is worn out? Unfortunately, when you can hear that
the needle is worn (a hissing sound from the record) or see shavings on the
record, it is already too late - the damage has been done. An easy way to
determine needle wear is to keep track of approximate hours the needle has
been in use. When gauging the length of time a needle will last, many variable
must be taken into account. Things like the tone arm weight, record condition,
dust in the air, whether a monaural or stereo needle is being used and tip
material of the needle all contribute to needle life. If the above conditions
are controlled, you may expect the following hours of play from your needle:
WHY YOU MUST REPLACE YOUR PHONOGRAPH NEEDLE
Limit of Use of These Needle Materials:
DIAMOND - 400 to 600 hrs. SAPPHIRE - 40 to 60 hrs.
It's a fact - a quality stylus tip makes the music.
The most important part of the sound reproduction system is the stylus tip assembly. The four major causes of record wear by a phonograph stylus are: Stylus Force, Effective Tip Mass, Stylus Tip Shape and Stylus Tip Polish.
TIP POLISH: Better polish means less record wear, smoother music and longer tip life.
TIP MASS: Light weight materials employed at the tip and the cantilever results in reduced effective tip mass.
STYLUS FORCE: The greater the tracking force, the greater the record and needle wear.
TIP SHAPE: A Shibata style tip is best for stereo or quad reproduction as its expanded contact area reduces the force and friction at the record groove. This provides a double plus: longer tip life and longer record life. An elliptical or biradial tip follows the undulations and contours of the record groove extremely well and is slightly more expensive than spherical.
Spherical is the original tip developed to play back records and is still widely used today in less costlier sound systems.

Examples of West-Tech's cross reference guides to supply optimum needles for the best sound are shown below. Note on these pages reference to the cartridge number and needles to be used in each, variety of needle materials and tip sizes(mils). Some cartridges require two needles of the same number, just different point size (mil).

Often mistaken as stylus, these are actually cartridges with stylus. We do carry in stock a complete line of popular power point/plug in cartridges for older sets. These units are tested and guaranteed. If you have problems identifying your cartridge, you can double check by also comparing the plug-in socket diagram to the right of the cartridge diagram.
