Service/Upgrade of a Linn Kairn Pre-amplifier

Servicing of a Linn Kairn Pre-amplifier. There was a suspicion that there was a noise problem with this amp but it turned out that its just got a bit higher gain than your average pre-amp. A modification was made to the amp to give a lower level output that will be better suited to power amplifiers with more gain than a Linn.

There is a backup battery that needs replaced in these units and the front flap usually has some failure.

We also explore the 'Brilliant' supply and do some re-capping there.

Serial Number of this unit: 008148

Excellent modification for sound quality! It appeared there was a layout for a linear supply and I was hoping you were going all out and toss the SMPS:)

Great Video! Can you please add a list of all the electrolytic caps that need replacing in the slimline SMPS? I have a much loved Kairn with slimline SMPS that is beginning to show signs of wear in the psu and would love to restore it before it gets worse.
