For sale is an ARC SP-16 preamplifier with phono outputs. The unit is in excellent condition. It was sent to Audio Research in Nov 2011 to have the tubes replaced, and has a new (under 15 hours) set of 6 matched and balanced JJ Tesla Gold 12AX7 tubes. Since being returned from the factory the unit was barely used and has been in the box for the past 4 months. I am selling because I no longer need a phono pre. Factory double box, remote and manual are all included. The asking price is firm. Shipping charge is actual cost via FedEx ground to the continental US. Paypal is accepted, but seller pays the 3% fee.
