This was originally purchased from an Audiogon member. Upon receipt one of the channels was not working. The fuse on the PCB was open. All other channels were operating properly. I replaced the open fuse with the exact replacement and the channel operated properly. Sometime later this channel developed an intermittent static noise. I am selling this unit with full disclosure in order to let any prospective buyer be aware of its condition. I am sure this is a minor issue on this PCB but I do not have the time to continue to its resolution. I have discounted this amplifier to reflect its condition.
