LP12 owners: Is it about time you had your turntable serviced ? LP12's require some servicing every couple of years. Doing so ensures that you get the best sound quality as well as ensuring that long term damage is prevented. New springs, grommets and bolts will tighten-up the sound as well as ensuring the turntable stays set up longer. At the same time the bearing can be lubricated and we can provide a status report on things like the belt and the stylus. The last thing you want is a damaged stylus ruining your precious vinyl.

The good news is that a full service including all the new upgraded bits will only cost you £50.00 plus parts

It is also recommended that if you have a Valhalla power supply fitted that this is overhauled every 10 years. As this board is now no longer available it is definitely wise to have it checked out. We can also check and carry out upgrades and factory modifications to this board if required.

Cost is normally around £48.00 on earlier boards including return postage in the UK

Of course we can also take the opportunity to advise you of potential upgrades for your turntable or merely ensure that you get it back sounding as good as when you first bought it.

Although now no longer available from Linn we occasionally have used Valhalla power supplies in stock, this represents a huge upgrade if you have a basic power supply fitted. Call us now for prices and details.

Call 0114 2726466 to book in your turntable.

We can even offer a same day service if you arrange this in advance.

We also service Rega, Roksan, Dual and Technics 1210 turntables.

We can also supply drive belts, styli, cartridges and many other parts for most turntables, at very good prices. Please call or e-mail us with your requirements. See contact us page for details.

Linn LP-12 basic power supply

Basic Power Supply

Valhalla Power Supply

New, improved metal TRAMPOLIN base board

A new base board which uses aluminium in place of melamine (as used in the original TRAMPOLIN) for increased rigidity. The material is acoustically deadened to provide even better audio performance.

Features

Metal base board makes the TRAMPOLIN base more rigid and acoustically deadened.

Advantages

Deadening will reduce vibration and therefore will not be affected as much by interference from the surrounding environment.

Benefits

Improved audio performance.

Cost is £140.00

Please note, if you have the original hardboard base fitted it is highly recommended you fit a new base, this greatly increases rigidity of the plinth.

T Kable

Silver arm lead

The new T.Kable from Linn is an analogue armlead for use with the Ekos, Akito and Ittok tonearms. The T.Kable is made to the same high standards as the current Linn Silver Interconnect cables but has been modified physically by careful design of the insulation and outer sheathing to ensure that when fitted to the LP12 turntable the suspension operates in the correct manner.

This cable offers a significant upgrade over the standard cable supplied.

Cost is £280.00 for 1.1m or £330.00 for 1.7m

Cirkus Bearing Kit

The LP12 has had many upgrades through the years. The major ones were given exotic names, like Nirvana, Valhalla, Lingo, Trampolin reflecting the advances in accurate sound reproduction which they represented. There have also been many unnamed improvements like new feet, new baseboard, new armboard, new suspension springs and grommets and new plinth. The list is long and it means that an LP12 need never be out of date.

The Cirkus upgrade to the LP12 focuses on bearing performance and the connection of the bearing housing to the sub-chassis. The improved bearing and stronger sub-chassis arrangement provides the turntable with greater stability and ensures the bearing sits perfectly true to the chassis of the turntable. This in turn minimises the risk of turntable platter movement with respect to the sub-chassis and arm. Even the

slightest movement will introduce audible degradation to the reproduced

signal. Together the changes to the bearing and the sub-chassis make an enormous difference to the overall performance of the turntable. The specific changes are as follows:

1. The thickness of the bearing housing mounting flange has been substantially increased and undercuts eliminated to make it many times more rigid. This also allows the use of larger mounting bolts.

2. Increased distance between top and bottom liners in the bearing housing to make it as stable as possible eliminating even the smallest amount of rocking

3. An increase in the height of the bearing housing from the top of its inner liner to increase oil capacity, ensuring proper lubrication of the top bearing at all times.

4. Double thickness sub-chassis to improve rigidity, reducing flexing and improving control of the relationship between key components The attached kit of parts, which includes a new inner platter and spindle, is supplied to fit this upgrade. As always with Linn product improvements, new LP12 turntables will incorporate this upgrade as standard.

Cirkus bearing, sub chassis and inner platter

The full kit also includes;

A new arm board, springs and grommets, bearing oil and 2 new drive belts.

We can offer a same day fitting service if arranged in advance.

Cost is £410.00 Which includes fitting plus full service and alignment.
