McIntosh C28 All Analog Preamplifier - Super Clean

$0

This is one of the cleanest C28's to come to our shop. It's evident the previous owner took great care.

The C28 is the best preamp from this era in our opinion. It's easy to service, has a low noise floor, great vintage looks, and every feature we would want. The individual left and right tone controls are a nice plus.  

Cosmetically it's close to perfect - the glass is perfect and the paintwork and stenciling are super nice. It will be hard to find another in better condition. 

This has been fully tested in our our lab where it performed flawlessly.

We also have an official matching McIntosh wood cabinet available for an extra $400 which includes the shipping in a separate box. Just click the option at the bottom to add before checking out.

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.
