November 1990 copy of Hi Review which had the cover headline "LINN LP12 LINGO THE BIGGEST UPGRADE YOU WILL EVER MAKE".

On page 30 to 35 was the write up by Chris Frankland which contained the following technical content.

"Linn knew that the motor power supply was a vital part of the turntable's performance and that there were many areas where Valhalla was deficient. For a start there was the problem that one was supplying an accurate 50Hz from the crystal but that would beat against the less accurate 50Hz cycle from the mains itself and cause a very low frequency beat signal (0.5Hz say), which was quite measurable. Also using a capacitor to determine phase also meant that it could not react to fluctuations in motor drag and the mains itself. The capacitor also allowed a lot of high frequency rubbish to get through, which was undesirable."

Some discussion about a Valhalla replacement called Wakonda not transcribed.

"The real solution was to house the power supply in its own separate box, allowing the use of a mains transformer to be used for the active circuitry without this intefering with the signals from the cartridge.

Lingo uses two Class A amplifiers, one for each phase of the motor. Both phases are therefore driven actively, which eliminates the variables associated with passive drive and the series capacitor from Valhalla. Thus the motor is more immune to vagaries of the phase shifts caused by mains supply and motor load conditions. For this reason they have been able to dispense with the cup, spring and ball peviously used to put pressure on the motor drive spindle from underneath, as this, they now discover, was obviously helping to isolate it from loading by the suspension, belt drag and so on."

Some discussion about sourcing the crystal oscillator not transcribed.

"Significantly, the Lingo uses much more sophisticated filtering and now they have achieved a situation with both phases accurately driven, where this increased level of performance is completely independent of mains and load fluctuations. Indeed, Lingo has put the mains beat frequency problem down at less than -100 dB in level, whereas before they tell me it could easily be measured with an ordinary multimetre.

A trick they used to good effect in the Axis turntable has been borrowed for the Lingo.With Valhalla the drive voltage to the motor was about 85-95V. For the Axis to give it less motor noise during ordinary load conditions they built a circuit which applied a high voltage, 85V, to give it the necessary torque at start up, but once the motor was locked to speed, would drop the voltage to 65V. This meant that motor noise was a lot lower."
