Audio Research LS17 Tube Preamplifier

For your consideration, we have a beautiful example of an Audio Research LS17 Line Stage Tube Preamplifier. The preamp has been lightly used, and is in excellent condition, both inside and out. We took the unit in on a trade with a client of ours who upgraded to an Audio Research Reference 5SE. The preamp is in perfect working order, and sounds excellent. Like all units that come through our shop, the preamp was checked out on our bench and later in one of our house systems under normal listening conditions. 

Physically the LS17 is in excellent condition, with no visible flaws. The inside is just as clean as the outside. Please see the many pictures in the listing for further details. 

The tubes tested like new on our Amplitrex AT1000 tube tester. See results below.
