TESTIMONIALS

MMC stands for 'Moving Micro-Cross'; the patented moving-iron principle
upon which all B&O cartridges were based. This unique system
employed a cross-shaped armature which, among other advantages,
guaranteed exceptional stereo separation since each channel moves on a
separate axis.
The job of any pickup cartridge is to transform the record's physical
profile (groove modulation) into corresponding electrical signals
(which are then amplified or enlarged by the amplifier and turned into
audible sound waves by the loudspeaker.
A cartridge must perform three separate and exacting tasks if it is
to do this job successfully. It must function mechanically (the
movements of the stylus in the groove); it must function magnetically
(using the physical movements to create changes in a magnetic field);
and it must function electrically (using the changes in magnetic flux to
generate an electrical current). At each stage, one type of energy is
transferred into another, quite different, type. And the transfer must
be perfect, with no energy lost and none added from extraneous sources.
No cartridge will ever reach this ideal unless the Laws of Physics
can be repealed. However, by understanding the relationships between the
three transfer stages and continually applying refined engineering
techniques, B&O's belief was that each stage of cartridge
improvement would bring each successive cartridge closer to the ideal.
Record wear and the cartridge
If you take music seriously the value of your record collection is
likely to be high. Many of your records are likely to be irreplaceable.
You will also know that the signals pressed into your vinyl discs are
very fragile indeed. The pickup cartridge can be the disc's worse enemy
since an ill-suited cartridge can mark a record for life in a single
play.
While B&O is aware that cartridge specifications are
inter-related, their research shows consistently that Effective Tip Mass
(ETM) is one of the major factors affecting record wear. ETM is the
equivalent of the amount of inertia the groove 'sees' in moving or
accelerating the stylus tip. Consequently, the higher the ETM value, the
higher the force required for a given constant acceleration. Obviously,
more force results in more wear.
Three elements contribute to ETM. The stylus tip (diamond)
contributes with its entire weight and mass. The armature contributes
between 5 - 20% of its weight and mass; the cantilever around 30%.
B&O has been able to reduce ETM substantially by refining these
elements and building them into an integrated unit. The result is a
system which not only reduces damage to the groove walls dramatically,
but also provides exceptional performance at all frequencies.

carriage may cost more OR LESS!! than the listing states (I have to
enter an estimated figure) and will be charged in full as per the
service chosen and destination country. Eg, air, surface, express,

Postage/Carriage charges:
You
may have noticed that these has risen lately. Insurance has almost
doubled and many carriers will not accept turntables, speakers or
amplifiers, meaning I have to find a specialist. I'm sorry that these
have to be passed onto you. Qualitronics aims to recycle packaging as
much as possible but it will always be top quality and usually it's
double-box where appropriate too.
DELIVERY TO CHINA, ISRAEL, AUSTRALASIA, INDIA, RUSSIAN FEDERATION AND SOUTH AMERICA WILL BE ROUGHLY DOUBLE THE QUOTED INTERNATIONAL PRICE. TO BID IS TO ACCEPT THIS EXTRA PAYMENT. THANKS!
About Qualitronics!
I'm
running this business part-time whilst I raise my children. My daughter
Issy is 5 years old, the apple of my eye, my teacher and the
beneficiary of your purchases. (She says THANK YOU VERY MUCH!) Tommy is
5-months old and his dimples charm the world. I endeavour to source the
HIGHEST quality electronics, mostly B&O HiFi and will have owned
most of the models in question at some time in my life. This gives me a
real experience of the merits to share with you. I'm a time-served Sound
Engineer and use my trained ear to check each audio item. It's not just
sonics though, look out for the weird and wonderful... as long as it's
well made
PRE-SALE ENQUIRIES:
I'm more than happy to answer any questions, offer advice and make suggestions over the phone and many customers have already found this useful.
Please call the customer service line accessed by clicking the "ask a question" feature or opening the "full information" link in the business information section below. The full number is not always displayed. Often the first zero is missing. This is ebay's procedure and not mine.
PRODUCTION DESIGNERS AND PROPERTIES BUYERS
A
number of my items have now featured in TV ads, theatre and film
productions and professional photography having been bought by
production designers, location agents and properties buyers. These
include a Beocenter 2200, Beocenter 7007 and Beovox S45 speakers among
others. I recognise the tight deadlines that you have to work to and the
immediacy you often have to work under. For the speediest solution I
can offer, including same or next day delivery, suitability of product
or advice on matching items to an era (or decade), please use the customer service line accessed by clicking the "ask a question" feature or opening the "full information" link in the business information section below.
COLLECT IN PERSON:
This is actively encouraged! This way, no clumsy or disgruntled delivery person can break it! Do check in advance the location of the item you're interested in. A quick call will be all that's needed to confirm the whereabouts.
Whilst the business is registered in London, I also have stock stored near Maidstone, Manchester and the Midlands.
I can only accept cash on collection as the payment method if visiting the premises due to the PayPal charge back scam.
INSTALLATION:
I am increasingly being commissioned to complete installations of the products that I sell.
Depending upon your location and items purchased this can be achieved for little more than the usual shipping and insurance costs of the selected units.
You receive the assurance of a properly connected system, including optimum placement design and the benefit of a full demonstration, highlighting the tips and techniques garnered from decades of experience and expertise.
Recent installations have ranged from a single Beocenter being connected to the existing speakers and unit for an 89-years young-lady for a few hundred pounds to a multi-room, Beocenter, Beogram, Beovox and B&O dedicated cabinet and stands combination, with remote control, for a few thousand pounds.
Please use the "ask a question" feature to access the pre-sales telephone number to discuss your requirements.
SOURCING SERVICE:
Can't find that B&O product that you've yearned for since you were a kid? Need a rare or discontinued part to repair your unit? If I don't have it in stock, then I can normally source one very quickly.
I have a wide network of fellow enthusiasts, collectors, dealerships and retired B&O Engineers whom I can call upon to fulfill your needs.
FEEDBACK:
Your positive feedback is vital to all good sellers. It let's us know that you are happy, if not delirious, about your purchase.
On very rare occasions, there may be an issue with your order, such as courier damage or simply leaving transit screws engaged. (Quite common). I can remedy any such issues to your complete satisfaction most quickly via the telephone or eBay message (without the need to open a case). Please use the contact number shown when you select the "ask a question" button.
I realise that you are very, very busy, only one in three of my clients has found the time to leave feedback that also informs their peers of their positive experience. Indeed all of Qualitronics' feedback is from buyers and not inflated by that of other sellers. Your contribution will be greatly appreciated.
INTERNATIONAL PURCHASES:
Please note that Qualitronics is not responsible for any additional import tariffs or customs charges levied at source or upon delivery. It is the buyer's responsibility to check before purchasing for their own country's charges.
VOLTAGE:
All electrical items are UK voltage (240v) and B&O UK "type xxxx" unless otherwise stated.
