About this manual
This manual deals effectively with three quite distinct amplifiers. The amps have enough in common to justify
this approach and this avoids the confusion that might come with separate manuals. Any differences
between the types will be dealt with in the “Circumstances” column – e.g. Applies to LK280 only.
This manual is designed to help you, as a Linn Retailer or Distributor, to repair as many LK2 faults at your
repair centre as is practical and so provide the best possible service for your customer should a problem
arise.

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.
Spare Parts Availability and LK2 repair
Please note that the LK2 has been discontinued for some considerable time now and as such, we cannot
guarantee the supply of spare parts – many are simply no longer available and some others are no longer in
stock. Some part numbers are listed throughout this manual, but these are provided for information only and
this does not imply that these parts will be available should you request them.
Linn guarantee that we will support a product until 5 years after the final build. We take this obligation very
seriously and also go much further. Beyond this date, we will repair any Linn product that we possibly can,
where it is within our power to do so. However, due to the difficulty with the availability of spare parts, as
explained above, it is occasionally not possible to repair a product or supply parts for repair, if the necessary
parts are not available.
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.
Also read the “
LK2 fault finding – Hints & Tips
” section below as the information contained there may save
you a lot of time.
If you are unsure about the meaning of any words or phrases, look in the
Glossary.

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 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 (and bear in mind that there may be more than one fault). For
