This freshly serviced Linn AV5105 ready to rock your system for another 20 years.

This amp was originally part of a $27,000 Linn system circa 2000, that with inflation would be nearly $50k today.

It features a dual-mono design for "maximum separation and performance" that's completely isolated on one chassis.

You won't find this on another amp anywhere near this price today.

Plus this is 230V compatible with the flick of a rear switch and fuse swap.

From a 1999 Stereophile review written by the one and only Michael Fremer:
The 5105 stereo power amp is a wideband (2 Hz—50 kHz) dual-mono design: two separate amplifiers sharing the same chassis but isolated from each other and from ground.

The circuit is direct-coupled and servo-controlled, meaning there are no potentially sound-degrading coupling capacitors in the signal path. A signal-sensing circuit automatically powers the amplifier from Standby mode.

SkyFi Service Notes:
• Replaced main filters, all SMD caps, and a number of other caps.
• Most importantly we performed the official Linn service bulletin on this model related to a nearly 20-year old recall.
• We contacted Linn for exact specifics on this service bulletin, and then changed the two 63V 10000uF capacitors to 80V 6800uF as directed.
• Tests with perfect channel balance up to 100W per channel into 8 ohms.
• Sounds excellent on listening tests.

*Please note the Linn speaker adapters/connectors are *not* included with this listing. "BFA (British Federation of Audio) safety compliant connector was developed for use on certain high quality audio amplifiers from Arcam, Linn, and Cyrus."

We don't have any in the shop to include right now, but you can easily find them from several sources online. Search for  BFA Speaker Connectors. Or if you're like most of our Linn fans you probably already have speaker cables terminated with the proper Linn adapters!

More from Linn:
The new Linn AV 5105 Stereo Power Amplifier is a compact, high quality stereo 400 Watt power amplifier. It is engineered to complement all the other components in an AV 51 System and is constructed to match the AV 5103 System Controller in style and performance.

The AV 5105 Stereo Power Amplifier combines high output power, ruggedness and ease of use with the accuracy that results from Linn’s passion for sound quality, and draws on many years of experience in the design and manufacture of high quality audio power amplifiers.

Power, precision and high signal handling quality mean that the AV 5105 can perfectly reproduce the most dramatic, subtle and complex sound effects simultaneously. It is a versatile, stackable design that can also accommodate active modules internally for optimised loudspeaker control.

The AV 5105’s low operating temperature and sophisticated protection circuitry helps make it flexible. To permit remote location of the amplifier it also has auto turn-on and switch-off signal sensing circuitry, which automatically brings the amplifier out of standby. A fully regulated and integrated power supply makes the AV 5105 immune to mains voltage fluctuation or noise to ensure the accuracy and consistent performance required for the most intensely involving film and music sound experience.

The SkyFi Testing Process for Solid State Amplifiers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale signs of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
