Linn Klout Solid State Amplifier - LINN'S BEST AMPLIFIER EVER

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
Highly reviewed and regarded amplifier from Linn, employing a single pair of transistors for each channel providing the most natural amplification you'll ever hear. 

Especially when paired with Linn speakers like some of these on our store (Click Here).

All made in the UK.

We have a total of two of these amplifiers currently available for purchase, which is perfect for bi-amplification.

Fully tested in our lab and driven to full power without issue.

Cosmetic Notes:
The top cover has light wear. There seem to be two faceplate versions of this amplifier. The face on this unit has a smooth gloss finish.

LINN KLOUT - Stereo Power Amplifier
Provides the uncompromising power, stability and performance required to drive any loudspeaker to the highest standard of musical accuracy.

- Two separate amplifiers in one box each with its own fully regulated and isolated power supply for the ultimate loudspeaker control and stability
- Protection circuitry which does not limit output current. (protected against: transistor overload, instantaneous over-current, short circuit, over-temperature, over and under voltage, DC input, power supply in-rush current)
- Advanced circuitry to maximise loudspeaker control and protect the amplifier and loudspeakers from overload
- Three sets of speaker outputs for optimised bi-and tri-wiring upgrades or driving auxiliary loudspeakers
- Parallel line-in/line-out connectors for ‘daisy-chained’ multi-amplifier installations
- Remote switch-on facility to enable freedom of location and system configuration
- Front facia bi-coloured LEDs to indicate product status
- Massive heatsink extrusion for cool, stable performance
- Fully screened transformer to allow hum-free stacking
- Linn active crossover modules accommodated internally for improved playback
- performance and simple active system installation
- Surface-mount electronics to improve heat dissipation and reliability, and provide
- optimum signal handling
- Ultra-short signal path, which preserves music signal integrity, in a very compact package

Testing Process:

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.

If the amplifier passes visual inspection, we move on to a controlled power on sequence using a Sencore safety analyzer to monitor current draw in real time. Once the amplifier is determined to be safe to operate, we connect it to full AC mains for function and power testing. We connect the speaker outputs of the amplifier to a Sencore PA81 Power Analyzer which acts as a dummy load, DC offset monitor, and oscilloscope interface. We start with a low level 1 KHz test signal at the amplifier's input and slowly increase its amplitude while monitoring the output on an oscilloscope for signs of noise, clipping, distortion, or improper channel balance. We continue increasing the signal level until the amplifier reaches clipping.

At this point we take an output power measurement and compare it to the spec sheet of the amplifier to verify proper performance. If the device under test has both balanced and single ended inputs they are both tested at this time.

We finish off the bench evaluation with a 1 KHz square wave check and a 20 Hz to 20 KHz sine sweep to assess the amplifier's frequency response characteristics.

This battery of tests will usually reveal if the amplifier has any issues that need further attention.

Before the device leaves the bench, we perform a listening test with actual music using a variety of preferred test tracks. Our benches are outfitted with familiar monitor speakers which help us identify inconsistencies that will not always show up on our test gear. The main things that we are listening for are hum or noise with no signal present, proper center image, clicks, pops, or any other obvious undesirable audio characteristics.

If the unit passes all of these tests it is moved to our long term testing rig where we simulate real word operating conditions for 6-8 hours minimum. This allows us to monitor the unit for signs of thermal runaway or intermittent issues that only crop up when the unit has fully come up to temperature.
