Nakamichi CA-7A Vintage Analog Preamplifier With MC/MM Phono - See Video

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

We love this piece and the matching Stasis PA-7AII amplifier so much that we did a full length video detailing its awesomeness.

Since the video shown below covers all the features I won't go into depth here.

This is the desirable later production "A" designation CA-7A. 

Capable of MC (Moving-Coil) - Or - MM (Moving-Magnet) Phono. On the front panel there's a single Phono source selection option. Then on the rear of the unit you'll see dedicated MC/MM input jacks plus a MC/MM selection switch.

Your purchase also includes the super rare remote control and original manual!

Condition is superb, likely the cleanest we've seen to date.

Tested, cleaned and fully tested in our lab and listening room.

Service note - Both left channel output jacks were professionally replaced and tested for full functionality.

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.
