McIntosh C2500 Tube Preamp

McIntosh C2500 tube pre-amplifier in excellent cosmetic and operating condition.  Includes all original accessories and packaging materials (power cord, remote, owners manual, box).  Approximately 3 years old, bought new from an authorized dealer.  Read excellent reviews online.  Includes digital inputs with DAC and built-in MM and MC phono preamp. 

Only one small issue:  One of the trigger control outlets doesn't work because the male end of a 3.5mm control cable broke off inside the jack.  The preamp has two other power control trigger outlets, so you can still use the preamp to power other McIntosh units on and off.  Otherwise, the unit operates perfectly.
