I've owned this Rev 5 for over 10 years, but it has not seen much use. I recently had it fully serviced, as the wet output was not audible, so my tech re built the power supply and re capped as needed. He also replaced a badly frayed power cable. I bought a remote from another seller so I could package it with this unit. I tested everything, and it all functions as it should, and sounds fantastic. Owner's manual is also included. Reasonable offers considered - please email any questions. Thanks for looking!
