Shindo Laboratory Monbrison Tube Preamp with Phono - RARE

$7,999

This is the original version of this rare hand built preamplifier with extremely low production quantities.

This example is serial number 28 and is not to be confused with the new model with does not have facilities for both MM (Moving Magnet) and MC (Moving-Coil) for phono. 

This is a collectible piece with a huge following and is sure to be a good investment over time. MSRP was in the $9-10k range when new. 

Great cosmetic condition with no noticeable scratches or dents. The front clear display window is a bit hazy, but shows great.

We serviced all of the switches and controls and tested all functionality carefully in our lab where it sounded great throughout.

Tubes include vintage Telefunken ECL94S and various SLC Special Selected Tubes.

The matching amplifier and power conditioner are also available as a complete set.

The SkyFi Testing Process for Preamplifiers:

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 sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline.

At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching.

Final testing involves putting actual music through the preamplifier We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage KEF speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
