About this manual

This manual is designed to help you as a Linn Retailer or Distributor to provide the best possible service for
your customer should a problem arise. The LK85 and LK140 share many design aspects and parts, so it
makes sense to cover both amplifiers in the one manual. Most faults, cures etc apply to both amps and if no
distinction is mentioned, it is safe to assume that it is applicable to both amps. They are not identical,
however and any differences will be mentioned as they arise throughout the manual.

Retailer & Distributor Obligations
Linn Specialist Retailers or Distributors are obliged to carry out the repairs in this manual under the terms of
the contract & warranty agreements. You should return a faulty product to Linn for repair, only if the fault is
not covered in this Service Manual. If a product, which is under warranty, is returned to Linn for repair and
the fault is covered in the service manual, Linn may levy a charge and this charge should not be passed to
the customer.

How to use this manual

The main body of this manual, the fault table, is designed to be as quick and simple as possible to use when
you are confronted with a faulty product and so it is arranged by fault symptom as the symptom is usually all
that you will know about the fault.
If you are unsure about the meaning of any words or phrases, look in the Glossary. (accessible via Linfo
Website - Product Information)
Before embarking on any Service work, you should read the Service Procedures section (accessible via
Linfo Website - Product Information), as there are certain procedures that must be followed in order to
ensure the problem is resolved quickly and permanently.
Table of contents & fault symptoms
Look firstly at the table of contents and find the category that you covers the symptom you are seeing, then
look down the list of faults in that section until you find the symptom or symptoms that best describe the
problem.
Circumstances
Then simply follow the table along – the table specifies circumstances surrounding the fault symptom – e.g.
whether the fault is likely to be intermittent or constant, if the fault only occurs within a range of serial
numbers etc.
Possible causes
The next column details possible causes – this is effectively the most important section, probably the main
reason you are looking at this manual at all. There may be several possible causes for the symptom you
have – it is worth checking out all of these (maybe there is more than one fault). For some faults, simple
checks are detailed that you can use to rule out the problem without replacing any parts, whereas for other
faults, the simplest way to rule out the problem is to replace the component(s) listed
Cure
Quite simply the action that you must take to cure the problem.
