Linn Lingo II LP12 Power Supply and board

As new Lingo version 2 in full size LK box. Huge upgrade to anything less and a cost effective alternative to the new Radikal. In February 2001 at serial number 614522 Linn changed to the full size LK box for the Lingo. This unit is serial number 630013. From the Linn Forum: "Linn don't refer to the Lingos as the Lingo 1 and the Lingo 2 as they have made so many changes to the Lingo over the years. This was explained to me by my Linn factory tour guide in 2008." I toured the factory in 2005 and was told bascially the same. From Art Dudley in Stereophile: The technology behind the Linn Lingo is a great deal less obvious. As with its predecessor, the above-mentioned Linn Valhalla power supply, the Lingo is a motor-drive unit that synthesizes its own 50Hz reference signal, regardless of the country in which it's used. But removing that circuitry from the turntable proper and putting it in a separate box gave Linn's engineers an opportunity to do a bit more than just that—and they took full advantage of it. Like the Valhalla, the Linn Lingo uses a crystal oscillator to generate its reference signal, but the active filtering used to strip the resulting squarewave of all its harmonics is much more sophisticated in the Lingo. The Lingo also feeds that signal to two separate class-A amplifier circuits, one for each of the motor's two phases. Doing it that way allows the Lingo to maintain a very precise 90º between the two signal phases, which goes a long way toward eliminating motor vibration—much more, Linn says, than a comparatively imprecise passive phase-shift network. The Lingo has other tricks up its extruded sleeve. While designed to maintain a rock-steady output frequency, the Lingo actually varies its output voltage—and thus motor torque—in response to need. On startup, the Lingo's voltage is set for maximum, but once the platter gets to 33.3rpm, the voltage is reduced to produce only the amount of torque needed to maintain a steady speed. Also, pushing a single button can tease a 67.5Hz sinewave out of the Lingo—which is precisely what that 50Hz motor requires to spin the platter at 45rpm. Take that horrid old 45rpm pulley adapter and toss it in the dumpster. If you buy a Linn LP12 with a Lingo supply as standard . . . well, there you go. But if you buy a Lingo upgrade for an LP12 that's already in service, then you'll get more than just the outboard box itself: You'll get a new on/off switch, a new power-supply umbilical cord, and a new turntable circuit board, too.
