Excellent phono pre-amp from Audio Research's current Foundation Series.

I bought this new just a few weeks ago and finances dictate I need to move some equipment.

The preamp has only about 120 hours on the tubes. It is in "new" condition.

Buyer pays shipping and Paypal fees of 3%.

Here is Audio Reseach's description of this great pre-amp:

The PH9 phono preamplifier is a great pairing with most cartridge and turntable combinations. A trio of 6H30 vacuum tubes are at the core of a simple and clear signal path to provide the most transparent preamplification possible. Five different impedance settings allow for cartridge loading, which can be changed on the fly with the included metal remote. Cartridge impedance, tube hours, auto shutdown, and other features are included in the menu system.
