You send in a B&O stylus or cartridge. It will be restored to perfect working order and sent back to you.
When completed the cartridge is like new, providing you chose the same spec as original, there are a range of specs available so you can upgrade or downgrade any cartridge as you see fit. This price includes the return postage via UK signed post (£50 insurance) and a 30-day satisfaction guarantee so if you are not completely satisfied with the audio quality you can return it for a full refund. All repairs are done on a rolling basis and you may receive a different cartridge/stylus this helps to reduce turnaround times, if requested the cartridge/stylus can be marked on arrival and you will receive the exact same unit back, This may increase the turnaround time, and will require permanent marking this will be done on the underside so it's not visible when in use.
Turnaround time on average is 10 days. All orders are done in order of arrival.
Make sure to include a note clearly stating who you are and what service you want. If this is not included there is large possibility I will not know it’s from you.
Trade in prices available on all B&O cartridges and styli no matter what condition.
A brief overview of stylus specifications
This is a basic stylus type and the most common, it will be the original stylus of many systems. The main drawback of this stylus type is its unable to accurately reproduce some of the higher frequencies, i.e. adds some distortions, particularly evident on classical music, none the less many people are perfectly happy with these styli. This specification is not usually offered because elliptical is a vast improvement.
Useful life: 1000 hours under ideal conditions.
This is a spherical diamond that has some of the front and back ground off, this allows the diamond to more accurately reproduce high frequencies The upgrade to elliptical is quite evident in sound quality in the vast majority of systems.
Useful life: 1000 hours under ideal conditions
This is one of the line contact designs it allows the diamond to more accurately reproduce high frequency’s, in comparison to the elliptical design, it has more contact area, and is able to track with slightly less force. This represents a further upgrade in sound quality over the Elliptical. In addition it lasts longer.
Useful life: 2000 hours under ideal conditions
Micro Ridge is an advancement of the contact line design, it lasts about 2x longer than contact line styli such as the MMC1. While sapphire has previously been a popular cantilever material of choice for high-end listening, it is more than matched in performance terms by boron. Boron is better than sapphire for audio quality due to being harder. It measures 9.5 Mohs with diamond at 10 Mohs and sapphire at 9 Mohs. Since it is harder than sapphire it is also much less likely to break in the event of an accident. This specification surpasses all original Bang and Olufsen designs.
Useful life: 4000 hours under ideal conditions
Take a look below to find the original specification for your cartridge;
SP14 bonded spherical
SP10 nude spherical
SP12 nude elliptical
MMC20S bonded spherical
MMC20E bonded elliptical
MMC10E bonded elliptical
MMC20EN nude elliptical
MMC20CL nude line contact sapphire cantilever
MMC3000 bonded spherical
MMC4000 nude elliptical
MMC5000 bonded contact line, titanium cantilever

MMC1 nude contact line, sapphire tube cantilever
A nude stylus is one solid gemstone, usually diamond. This gives the best audio quality. A bonded stylus has a small diamond bonded to a shank.
It is a small rod that holds the diamond, some people call it the needle. It is usually well protected with plastic coverings/guards above it.

If your coils are broken it is often not possible to repair the cartridge, and if repairs are possible they cost an extra £25, therefore, you may want to test your coils before you place an order.
Every stereo phono cartridge has two coils one for each channel. The best way to test that these coils are functioning as intended is to use an ohm meter to test the resistance. Each coil should measure about the same as the other. If both are the same or similar resistance then the coils are fine.
For B&O styli and cartridges this method can be applied for the MMC1-5 cartridge, the resistance should be approximately 700-800 ohms for this series. The two opposing pins are one coil and the other two opposing pins are the other coil. If both coils measure about the same resistance then it's fine.
For other cartridges the resistance varies but this method can be applied to any stereo phono cartridge. Or if you are able to play a record and audio comes from both channels as long as your system is all working correctly and mono is not engaged then both coils are fine.,
For the MMC20xx and MMCx000, these are difficult to test as the contacts are hard to get to. The easiest method is to use one of the ¼ inch adapters to make the contacts easier to test. If you do not have one of these then you can use thin probes to test inside. For this series the two furthest to the right are one coil, and the two furthest to the left are the other coil. The resistance should be approximately 700-800 ohms for each coil.
